Hello all,
This is in regards to a 1992 k100 (motronic system, NOT L-Jetronic). My pipes keep cracking at the weld where the meet and go in to the muffler. The last time I took them off to re-weld them, they had almost fallen apart completely and were really only being held in place by the mounting system for the exhaust. I have an idea as to why this is happening: I believe it's due to the missing rubber mount support for the catalytic converter. I had attempted to create a brace, but that brace just broke in half from the vibration down there.
So the question: Would taking the catalytic converter out of the exhaust system make a huge difference in running? Good or bad? As far as I can tell, there is nothing there feeding the computer or anything. I would think it'd just get rid of a little back pressure, make it freer flowing, and thus make it run a little better. I'd like to get a different exhaust system altogether. I really like the stock square muffler from the older k100s. Would that be a viable option? What are some good aftermarket pipes / mufflers that would work with this bike?
Thanks in advance!
