Hello all, I have been searching on here for a while now, and I hate to come in swinging but I needed to reach out for help. I am having a terrible rattle after installing 1 3/4 stainless works long tubes, and is pulling timing about 6 degrees according to Jay. I’ve wedged header wrap between the primaries/collectors, wrapped the trans lines and cinched them up, upgraded the exhaust clamps and had some connections welded while leaving access to trans pan for service, and retorqued everything about 5 times after heat cycling. It’s driving me crazy after such an expensive system. Dip stick tube is bent out the way and also wrapped just in case it contacts anything. The exhaust shop I bring it to says it’s resonance from so much flow going through the mufflex 24” single in causing the rattling sound? I’m looking into the j pipe just to try, I’m out of options. Help is much appreciated and sorry for the long post.
