It's making some noise, seems to be coming from the rear cylinder area maybe although I did T-Bone a car in April and that pushed the front tire into the right front pipe enough to leave a mark on the pipe.
Are there copper crush washers that the pipes get snugged up to or what sort of a seal do the pipes have? I could have deformed the seal in the front pipe in the accident.
At around 30K miles, where are the first spots that tend to perforate? It looks like a pain to remove the collector and maybe expensive too since I'll probably have to replace several special looking clamps and seals.
What sort of seals are there where the rear manifold extenders come together with the "joint" and the joint to the collector? Are there any substitute parts for those?
Are there any tips that can be offered to help me sort out how to find and fix the leak? I have taken a good look at all that can be seen without some disassembly.
It sounds kind of hardcore but I'd like to quiet it down.
