Any interest in an actual performance 4-1 exhaust for GS1100E?

Here ya go. http://www.coneeng.com/ When I check out the parts that are available here, there is a striking resemblance to a Basanni. By the time your done, you might as well have bought one. The MotoGp pipes are sweet. Webike out of Japan has some nice pipes also, but are $$$. Pipes on old bikes dont make much more power than stock? Want to run for titles? Full systems on new bikes work better but are spendy, slip on mufflers are what I call fuel converters. They convert fuel to noise.

I took the Yoshi-like pipe off my '83 and replaced it with a nice stock exhaust, was about 6 tenths slower in the 1/4. Granted there was no jetting change but it ran well, no pods. My point is that there won't be nearly that much difference between a bad 4-1 and a good 4-1.

What was the trap speed difference? That's where horsepower shows up the most.

Not performance ones, unless you can convince MotoGPWerks to crank out systems again. Systems currently available are far from optimal in terms of performance, this one is designed for performance first.




I agree with all you say, they are just some of the choices that have to be made. I don't really want to get into manufacturing exhaust systems, all I really want is one for myself and doing a small batch might make that feasible. The welding is so I don't have to worry about fitment on someone else's bike and mild steel is easy to work on in your garage. Welding stainless means TIG and most guys don't have that option available to them.

I'm just checking on interest before I go to the trouble to model an exhaust system in solidworks to get quotes on the CNC bending. If no one else cares (which is very possible) then I likely won't invest the time to build the model.

I bought my stainless system from Ripple Rock Racers in Toronto. The full system cost me $550cdn and is made by Hindle. I am almost ready to start putting my resto mod 100 Katana together and this system will go on it.

If you are wanting to make a performance header good luck. There has been a lot of improvement over the years with regards to collectors and the length of the collector. Also the length of the megaphone is important. I have made exhaust for Pro Stock motorcycles before and it is an art that is usually left to someone that has been doing it for years. I am not saying you cant make a nice header, but to say it will be a performance header with equal length primary's, it takes a lot more than that. Good luck and looking forward to see what you come up with.
