Open longtubes cause damage? I've heard from a few people that running open longtube hookers is bad. Is it? Would I be better off waiting for a ORY/3in exhaust? Just stuck on what to do...I have the stock manifolds/ypipe/exhaust on now, and just bought used longtubes.

How long are you planning on running it open? If it's only a short distance, I had no problems driving my car with open headers to the exhaust shop.

I said 20" should be safe. I know I've used some that were about 18-22" and it worked fine. I haven't tested to see what would be the abosolute shortest that you could use but I'm sure that would vary depending on O2 sensor placement and engine design (CI and camshaft could effect this somewhat.)
