zrothauser Posted January 6, 2010 Report Share Posted January 6, 2010 I have a 1995 3100 GP coupe. It has dual exhaust and currently the mufflers are rotted out. Someone suggested that I could put a single long narrow muffler behind the cat, and straight pipe the original muffler locations. Has anyone done this? Thoughts or opinions?

I'm sure it can be done, but it will probably be a bit louder. Not that a 3100 sounds bad with louder exhaust though. Quote Link to comment Share on other sites More sharing options...
MonteCarloChick Posted January 6, 2010 Report Share Posted January 6, 2010 Do you need a cat there where you live? If not, get rid of it and run it straight Quote Link to comment Share on other sites More sharing options...

sloick Posted January 19, 2010 Report Share Posted January 19, 2010 if you cut your cat off you will kill the poor people driving behind you. but your car will run alot better. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted January 19, 2010 Report Share Posted January 19, 2010 cut it and if the noise bothers you, run more resonators... VERY low flow restriction. Quote Link to comment Share on other sites More sharing options...
