Downsides to custom midpipe : Suzuki GSX-R Motorcycle Forums: Gixxer.com

I am looking into getting the new Italia Leo Vince exhaust canister and making a mid pipe so I can mount it off the passenger pegs.

I have all the recourses to bend, stretch, tig the mid pipe just unsure of the downsides of doing this.

I have a pcv with auto tune so I can get my afr where I want it. Do I need to be concerned with anything else like bad pressure and what not?

Hard to say as each bike is different. We know guys that have made their own midpipes and such and the bike ran fine. With the PCV and At you should be good to go, one would think.

I have seen some pretty wild stuff and the bikes seemed to run fine but I never asked any questions because I had never planned on doing this.

The main thing that worries me is the back pressure thing. Is back pressure affected by your afr only or does it also have to do with length of pipe and what not
