making exhaust

Here is what I am wondering, I have a 08 gsxr 600. Now I have been looking at some slips on for my bike and I was just wondering can I make my own exhaust. The throttle valve is on the cat and all the back pressure i need the cat can take care of right(or wrong). So basically I am just wonder if my bike just uses the cat for the back pressure will it run ok, and make my own tip. thks mg

I wouldn't do it. You risk fukin up your exhaust and/or engine. Just throw down a few hundred and get something that has some R&D behind it.

I have seen many others alter their stock exhaust, or even after market systems

I don't understand why you would want to though, probably won't hurt but probably not going to help any either.......


except for just getting that badass gsxr sound

so can anyone explain why a bike engine NEEDS back pressure, but say a 1.6 liter car engine that revs to 10k wants to avoid back pressure at all costs?

and as far as fabricating an exhaust, just work with anyone that can weld up mandrel bends and is skilled enough to make soe nice clean welds. it is not as if there are many complex bends that needs to be worked out...

I made one for my '06, but ultimately, I wasn't happy with it and abandoned the project.

Chances are that it will not have ill affect by doing the mod, but it won't likely make anything better either. If you make a pipe and remove the entire muffler system like I did, you'll be served well to have the bike re-mapped and dyno-tuned (there is one or two good places to get this done).

The exhaust removal is easy, making the pipes fit so that it can be secured well is a challenge.

"Romeo36" did the same thing to another '06 and he is happy with the results.

Here's a couple of pics from when I was fabbing and fitting:

newGSXR029

newGSXR030

newGSXR031

I couldn't find any of the band clamp style exhaust clamps locally and decided that I'm just going to get a slip-on from M4.
