Thread: exhaust leak source, repair difficulty?

dorman should have a catted down pipe direct fit. the flex is not a mesh flex, its like sliding metal parts.

I need to replace the piece with the cat in it to fix this? Uh-oh, I'm in California. It isn't always the case that a replacement cat is California-legal, even if it isn't "high flow". They have to meet OEM specs.

you could buy a off road pipe and have a shop weld back in the stock cat.

Thanks for the link. Did you look at the Dorman downpipe I posted previously?
