full delkevic exhaust

[outback_imp]

Is the pcv and or auto tune needed with a full open exhaust with no cat ??? All Stock on the intake side. 2014 standard. What would you guys recommend i do?? Is just running the pcv with the supplied map?? or the one for yoshi slip on going to be ok??

Delkevic claims no retune needed with their Full Systems on their website.

The one I installed definitely needed at the very least a PCV to see the power gains the exhaust is intended to give. The bike may *work* fine without the PCV or retune, but you won't see near the benefits without that. It's also important to mention that if you open up the exhaust, you need to open up the other end too. Open up your air intake . More air, more fuel, faster flow, better go.

for example, when i installed my decat headers and can, i also removed the air snorkel, widened the intake bells, and installed a PCV to adjust the fueling (with a map specifically designed to accomodate the changes i'd made). The results were significant, but you can tell that I could get more out of the bike with the right equipment. a PCV is kind of an "approximate" solution. my fueling is maybe 90% as perfect as it could be for my setup. If i also used the dynojet O2 sensor autotune system, i'd be even better off.

However, if all you want is gnarly noise, no you don't need a tune or a PCV.

If delkevic made an all black system instead I would be on the same wagon as you.

I still have stock headers but a shorty Moto gp exhaust tip.

It ran fine without the PCV but once I put the PCV on to compensate for an issue I had with the ECU flash it ran even better.

I have reached out to power commander many times to have them add a few more maps to the list of supplied maps since they didn't give us any options aside from a stock system with a slip on but they have never answered me back.

I changed the map from the all stock to the yoshi map recently and my brother said the front end is coming up easier than before hand.

So there may be a bigger difference between the 2 maps listed for the PCV than I thought.

Thanks for the info and help, I did plan on installing the tsr funnel in the side of the airbox to give it a little more air to go with the exhaust. bought one on ebay but never got it and finally got a refund.

The TSR intake funnel is not the same as the TSR airbox funnels. They are commonly confused on this forum.

The intake funnels before the air filter doesn't do much if at all.

What was referenced above was widening the intake funnels that sit on the throttle body( after the air filter) There is nearly a 10mm difference (if I remember correctly) between the funnels and the throttle body. So for some reason they restricted the flow and we think it was to meet emissions standards.

PowerDubs discovered you can just take the stock ones out and bore/hone them out and reinstall instead of spending the 500$ or so on the TSR kit.

I myself did this and just haven't installed the bored out funnels yet.

2014 CB1100, 1981 KZ440 LTD, 1993 Yamaha XJ600 Seca, 1994 Yamaha XJ600 Seca Thanks, yes i realize theres also the tb funnels that can be opened up. And if that airbox funnel doesnt do much than i wont bother with it. Im really just looking for a more knarly sound and really dont want to go through all the time and work of tearing it all apart to open up the tb,s and all that. The bike seems to run just fine and plenty quick and fast for my old butt to begin with. with that being said.
And with just a full open exhaust and no other mods is there anything i should or you would recommend i do?? What should i do with the stock 02 sensor?? I have a delete plug that plugs into the wire harness? And although no big power gain with just an open exhaust and running the pcv would it still be beneficial to run it?? better fueling ? maybe run a little cooler? I also have the auto tune but dont have a laptop to use it yet. Was thinking of having my buddy weld in the bung for it ,so if i decide to run it someday i wont have to pull it back apart. Thanks again for all your help!

This is correct, that's exactly what i did as well.....it was a lot of sanding a polishing and sanding and polishing and sanding and polishing to remove the material and get the plastic all nice and smooth in there.

keep them if at all possible, especially if you don't plan to modify the fueling and air in any other way. A lot of aftermarket exhausts for our bike still have the O2 Sensor bung in them and all you have to do is plug it back in. This will help your bike compensate for the changes. I'd strongly reccomend you check on this with regards to the headers you plan to buy and make sure you buy a set that has the O2 sensor bung.

as far as deleting it goes, when you install a PCV it comes with a blockoff cap for the connector that leads to the O2 sensor. so you plug in the cap in the connector where the o2 sensor used to wire up and just remove the sensor altogether, letting the PCV do the work. However, if you're planning on just removing it and leaving it disconnected with no other modification, that is probably not something i would go for.

My PCV5 never came with a sensor delete but I've seen it referenced many times. Did that come with the PCV3 possibly?


If you are just looking better sound negating the gigantic stock muffler will do. So you replacing the entire system will also do.

I like a loud bike and the stock headers and shorty moto gp exhaust gave me what the bike should have sounded like from the factory. It grumbles when you get on it but isn't ridiculous when you're cruising. You will like it when you put the new system on.


Also i below all delkevic come with the bung to install the factory o2 sensor but check with them.

The results were significant, but you can tell that I could get more out of the bike with the right equipment. a PCV is kind of an "approximate" solution. my fueling is maybe 90% as perfect as it could be for my setup. If i also used the dynojet O2 sensor autotune system, i'd be even better off.

However, if all you want is gnarly noise, no you don't need a tune or a PCV.

Thanks for the info and help, I did plan on installing the tsr funnel in the side of the airbox to give it a little more air to go with the exhaust. bought one on ebay but never got it and finally got a refund.

The TSR intake funnel is not the same as the TSR airbox funnels. They are commonly confused on this forum.

The intake funnels before the air filter doesn't do much if at all.

What was referenced above was widening the intake funnels that sit on the throttle body( after the air filter) There is nearly a 10mm difference (if I remember correctly) between the funnels and the throttle body. So for some reason they restricted the flow and we think it was to meet emissions standards.

PowerDubs discovered you can just take the stock ones out and bore/hone them out and reinstall instead of spending the 500$ or so on the TSR kit.

I myself did this and just haven't installed the bored out funnels yet.

This is correct, that's exactly what i did as well.....it was a lot of sanding a polishing and sanding and polishing and sanding and polishing to remove the material and get the plastic all nice and smooth in there.

The one I installed definitely needed at the very least a PCV to see the power gains the exhaust is intended to give. The bike may *work* fine without the PCV or retune, but you won't see near the benefits without that.

2014 CB1100, 1981 KZ440 LTD, 1993 Yamaha XJ600 Seca, 1994 Yamaha XJ600 Seca Thanks, yes i realize theres also the tb funnels that can be opened up. And if that airbox funnel doesnt do much than i wont bother with it. Im really just looking for a more knarly sound and really dont want to go through all the time and work of tearing it all apart to open up the tb,s and all that. The bike seems to run just fine and plenty quick and fast for my old butt to begin with. with that being said.
And with just a full open exhaust and no other mods is there anything i should or you would recommend i do?? What should i do with the stock 02 sensor?? I have a delete plug that plugs into the wire harness? And although no big power gain with just an open exhaust and running the pcv would it still be beneficial to run it?? better fueling ? maybe run a little cooler? I also have the auto tune but dont have a laptop to use it yet. Was thinking of having my buddy weld in the bung for it ,so if i decide to run it someday i wont have to pull it back apart. Thanks again for all your help!

keep them if at all possible, especially if you don't plan to modify the fueling and air in any other way. A lot of aftermarket exhausts for our bike still have the O2 Sensor bung in them and all you have to do is plug it back in. This will help your bike compensate for the changes. I'd strongly reccomend you check on this with regards to the headers you plan to buy and make sure you buy a set that has the O2 sensor bung.

as far as deleting it goes, when you install a PCV it comes with a blockoff cap for the connector that leads to the O2 sensor. so you plug in the cap in the connector where the o2 sensor used to wire up and just remove the sensor altogether, letting the PCV do the work. However, if you're planning on just removing it and leaving it disconnected with no other modification, that is probably not something i would go for.

If you are just looking better sound negating the gigantic stock muffler will do. So you replacing the entire system will also do.

I like a loud bike and the stock headers and shorty moto gp exhaust gave me what the bike should have sounded like from the factory. It grumbles when you get on it but isn't ridiculous when you're cruising. You will like it when you put the new system on.


Also i below all delkevic come with the bung to install the factory o2 sensor but check with them.

Thanks guys, My pcv didnt come with a sensor delete either. The delkevic header pipe did come with a bung for the 02 sensor. looks like its just in a different spot, its in the short pipe that connects to the collector pipe.
so it looks like i will just have to make up my mind to either just plug the 02 sensor back in the new header and run it OR hook up and run the pcv. HMMMMM decisions decisions

 

[misterprofessionality]

Fwiw, using the stock o2 sensor will yield the best and most reliable results. You won't get real power gains without digging into the airbox and all that good stuff, so using the PCV is only going to cause you to burn more gas unnecessarily. If you can get the gnarly noise and keep your fuel range intact, that's a win.

Thats good to know. It seems to use enough gas as it is. I guess i was under the impression that if you install a full exhaust on one of these new fi cb1100 bikes you had to run the pcv to keep it from running too lean. Hopefully delkevic did thier homework and put the bung where the stock 02 sensor cable will reach.

Thanks again for all your help, These new fi bikes is all new to me. Yea you definitely don't need it for just an exhaust. The stock ECU should be able to compensate.

A ton of us have our ECUs flashed by Guhls but they stopped the service earlier this year so you unfortunately missed the train on that one

Hopefully someone else will pick up the ability soon since Guhls will no longer jailbreak our ECUs

I imagine with these bikes popping up on the used market and getting newer/younger owners in the coming years there will be more people interested in the tuning/aftermarket side. I think these bikes will be sought out for the future Cafe builders and such in another decade or 2.

so i guess this is how these delkevic exhaust fit ! Not very good! It looks like the whole thing should have had a little more bend in it and about an inch or so longer to allow the collector pipe to tuck up in place and line up to the mounting hole and still have the head pipes fit flush with the doughnut gaskets. I guess all i can do is snug the nuts down a little bit and see where it lies, then force it up a just a little bit and make a litle pc to connect them together. Kind of disappointed they couldnt have made these things fit better.

Photos? Exhausts can be a pain to install sometimes. After a little massaging and jiggling they may fit better

Also sounds silly but make sure one of the original exhaust gaskets at the headers isn't in there still and then you're trying to push the new gasket on the new headers against it. That could be messing with your inch of length if the headers arnt all flush in the manifold.

Outback - I had the same issues with fitment. It was not great. I actually didn't even bolt up the mid pipe because the pipe was too short to connect to the collector with the bolt in. I think another member fab'd up a bracket to get it to work.

Basically, these are your options:
1. Bolt everything up how it's designed and risk an exhaust leak between the mid pipe and the collector because the pipes are too short.
2. Install everything without the mid pipe bolted up (You will see the mid pipe bracket about an inch in front of the CB bracket)
3. Fab up a custom bracket to get the mid pipe to bolt up with all the pipes in their proper places.

This is just what we have to deal with when we buy the cheapest exhaust.

Screw that id call delkevic and tell them it doesn't fit.

Is it possible its for a different model year or trim?

Oof. I went through this, and I had to do it twice! First I installed my delkevic end can on my stock headers, which took a very long time. Lots of "massaging and wiggling" as others have said. Then I had to take it off and do it again when I got my titanium headers. That was actually easier believe it or not. I did, however have a big problem with the clamp loosening and the muffler spinning on the pipe which caused me to go through two sets of carbon crush gaskets before Ordering one size smaller from delkevic and MASSIVELY torquing the clamp on with a hex head bolt and socket. After that everything was peachy but it was definitely an ordeal.

Tldr: you're not alone.
