another exhaust thread-wyvern - sonnyb_imp - 07-02-2018

I got 2017 EX I absolutely love that 4-4 exhaust. Does anybody put some mileage on it?Would chrome discolor with age and use?Would I need a power commander?

Thanks

It's actually a 4 into 2 exhaust, and I agree--I think it looks amazing. I try not to think about what it weighs. I have only just bought my 2017 EX recently and I only have about 300 miles on it, but I already know it is in a very mild state of tune. Great low-end torque for an in-line 4, but really not much muscle. The fueling at lower rpms is okay--not great, but I have not had any actual low end stumbles like some here have reported on earlier bikes. I'm not sure that a Power Commander would do much unless you're willing to scrap the exhaust and maybe do work on the intake side. Plus, I am not sure what is available to fit our bikes and if there is any off the shelf tune for it.

It is true 4 into 4 and mine have over 7K on them with no discoloration because the headers are double wall with Chrome , mufflers are Stainless Steel . they hold up great

I get no popping just a great sound. pipes 2 and 3 do have a crossover for the O2 sensor [ look close and you can see the crossover ] the SS is slightly Golden from factory but has not darkened. mine runs perfect in every way - sound is amazing . posted a pic so you can see the crossover - O2 sensor is on top of that in the middle

Thanks guys,I’m not looking to to increase power or make it a racer,just love it how it sounds and looks.
use2b,so there is no need for any ECU tuning or any fuel delivery modifications,just install it and enjoy beauty of it,right?

RE: another exhaust thread-wyvern - misterprofessionality - 07-03-2018

i'm going to ask a question that i hope is appropriate for this thread: how would any of you compare the pipemasters 4-4 to the Moriwaki RC4? advantages? disadvantages?

I’d bet use2b has his pair system blocked off somewhere and just isn’t aware of it.

Removing the cat generally makes a lot of decel pops otherwise.

you are probably right as i did not do any of the work and the outcome is perfection by the guy who did all of this. unfortunately he died of a heart attack and the bike was bought along with his other toys and auctioned.

Wow- that’s a bummer.

I hope his soul is glad you are enjoying it and posting pics here for everyone to see!
