my 04 gixxer 600 has a gutted yosh exhaust with a straight piece of pipe welded inside. Will this damage my newly found friend???

Most likely to damage your ears! :lol:

i can deal with broken ears but not a broken bike!!!!!!!!!!!! U KNOW WHAT I MEAN???!!!

Well, it will lean out the fuel mixture, which could possibly damage the engine. However, if the bike has a power commander and has been re-mapped for proper air/fuel ratio, then that pipe won't hurt anything. I would suggest you get it to a dyno and take a look at the A/F ratio throughout the power curve. If it's too lean, you have two choices: spend the money on a power commander and a custom map, or spend the money on a new pipe. Personally, if the pipe sounds good, I'd just get the power commander and custom map. Heck, even a normal slip-on will lean out the A/F ratio a bit and you'd be smart to have a power commander there as well.

WHY? It just doesn't make sense! :gary: if you ask me! That would be ruining a perfectly good exhaust!

if ur gonna do that u may as well just cut the pip off right wehre it comes out the bottom fender and runa straight pipe. same thing. plus it will make ppl ask, "wow where is the exhaust"


but im with GAS MAN on this one

 

[jeeps84]
