So I need to have my Rear Cat, the Pipe after it, and the Muffler replaced. The Muffler is being replaced to ensure that the problem does not come back.
What I wanna know is is it a bad idea to go with non OEM Parts? Especially for the Cat? Cats are made to government regulated specifications, but I have hear a lot about them not lasting...also should I just tell them no on the Muffler or is it worthwhile to swap out?
Any help would be great, or other questions about what I am asking please let me know.
