Evening all! I'm in the market for a new exhaust and like many other posts I have come across, I am a bit confused on which route I should take. I have an 83 QV with a *twin* or *dual* cat setup and cannot find an IPB anywhere that reflects how the system is put together. I have an incredibly vague memory and only remember that it looks to be a pieced together Euro style header-to-muffler with some intermediate piping to fit the cats in that small space. I am wondering... to those who are much more knowledgeable in the system, would it be feasible to just get rid of that extra piping and just get a Euro style muffler? or do I have to stick with one that's proprietary?
