WHAT?!?!?!?!?!?

 

I have a feeling that this thread has sidetracked, but you would most likely want to remap with a different pipe, whether it is from a 1 liter, or from it just being a freer flowing pipe. I doubt any of them would lean out the mix enough to burn valves, but why not compliment the pipe with a correct tune?

 

GP makes an ehaust but I think its primarily for the Yamis

 

I kinda like the arrow dual system. I wouldn't have it unless I had 5 cylinders though....

 

I was more referring to gains over a single pipe full system, but that is still a definate improvement.

 

well if you have a pipe that is not made for you bike, for the right back pressure or whatever it can burn your valves.... just like taking off your pipe to begin with right? i mean you have to have the right back pressure... someone back me up cuz now im doubting myself

 

With good reason

 

crazyness, first thread of mine that people got interested in... thanks for all the info , and if anyone has anymore info let me know

 

Having some backpressure is important, but it would most likey not solely cause you to burn valves.A freer flowing exhaust causes a leaner mix, and a leaner mix makes the exhaust temps higher. Exhaust temps that are too high can burn thevalves and ruin them.

 

well shoot idc much anymore haha. if im wrong then someone put a 1k pipe on a 6.. then tell us if it continues to run right. ill keep my yoshi pipe tho
