Exhausting Decison

[the Ferret]

Three times I put aftermarket exhausts on motorcycles. Regretted it all 3 times. They all sounded great when" getting on it", but the droning noise at highway speeds drove me crazy. I know you takes lots of trips ES. Something to consider.

I didn't vote, but at this point in my life I would always vote stock. If stock was not an option, I would choose Staintune.

Funny how we look at polls with our own bias. I see it as 1/3 for stock and 2/3 for aftermarket. My bias also has me thinking that, of those who voted "stock", the majority of them would have picked the Yosh if stock was not an option. Sooooo....I feel like it will either be stock or the full Yosh exhaust. Then again, I could always change my mind. LOL

You sound as though you used to be indecisive, but now you're not so sure.

Ferret, good point.

Cheers

Let me mull that over for a bit.

Even though I didn't vote I'll add this:

Much like buying a motorcycle — when it comes to purchasing an exhaust, the decision is typically driven largely by passion. If you're not drawn strongly enough to any one particular option to make a clear cut decision, then go with the path of least resistance and keep it stock. There is certainly no harm in that.

BTW ES ..how is the boy doing? Playing soccer again yet?

He's fine, thanks, Mickey. He had a jazz concert last weekend and a classical concert this weekend. Having a bum ankle for a few weeks doesn't hurt you too bad when you're a horn player. It was a little hard for him to get around campus with a trombone on crutches, but that was only for a week. He's home for winter break in a couple of weeks and I can't wait to see him...same for our daughter.

ES,

I'll confuse you a bit more and go against the BRASS

Its pretty split between stock and modified, after market cans are modified and will give you a different sound (edit:: BACK PRESSURE) and DB.

The after market Can was not even considered when I made a decision to modify do to it looking original, no performance benefit, retaining the Cat made no sense to me at the price point.

A full Yoshi will give you full inch larger downpipes, no cat and with the pair mod no farting on decel. You will notice nice gains in performance without any piggyback controllers, with perfect A/F ratio as noted by one of our members charts. Those richer A/f ratio will make the motor run much cooler than stock with the added fuel delivery.

As far as noise on the highway, I notice nothing abnormal than stock ( i do wear ear protection) but I'm sure i would notice some sort of hum,drone if it was there.

Now the thing is appearance, i personally like the look of the beefy exhaust against the black motor and the rear wheel showing off its appearance.

I will be honest with my opinions, I had a ZRX1200 a few years ago that came with a aftermarket can and drilled airbox. I closed the airbox and bought a stock can from a member and returned it to stock. The bike farted like crazy on decel. I caught a lot of crap on the site telling people stock was better, but its not the case here.

Thanks for your input, CIP. So, if I'm reading it correctly, you're saying that I need to modify my fuel controller in order to avoid popping on decel? How much does that cost?

The only thing you need to do to avoid popping on decel is the pair mod, which is the cost of a bolt (10 cents) and 3 minutes of your time. Its a very simple mod

No need for a fuel controller, the bikes ECU will correct A/F ratio unlike bikes with carbs.

Look at Rick's Numbers with no PCV, perfect 13.0 a/f running much richer than stock running the full Yoshi. He is running a bit rich on top like my bike which a fuel controller can correct but not necessary. You will add 8% HP which you will feel in the seat of your pants.

I piggyback controller can be added for additional fine tuning, Fuzzy's chart shows 92HP with a PCV and tune which is about 5hp more(no A/F ratio chart was shown) not sure if it was a happy dyno or not but his results are up there. Again the PCV is not needed for spot on throttle response.

"Coming into the final turn it's Keepitstock by a length with Staintune gaining ground in the run to the finish. Yosh and The Other look as though they were given a green apple and will still be running tomorrow ........."

ClassicVW, I would keep away from the drilling the stock. A friend did that, not to a CB but similar can. He listened to it for a week. It did not sound good. He then went for a replacement aftermarket. You could try it though. You might just get lucky.

Cheers

Hey, I didn't say "I" was brave enough to try it!
