Where can I get a bolt on exhaust . I want to get one from the headers back. I don't want to pay the $500 I've been quoted for welded exhausts at mufler shops. Both sides need to be replaced. I have 76 truck with a 350 and dual exhaust. My pipes need replacining. My mufflers are only two years old so they don't have to come with a kit but if they do it is o.k. I've seen the Kit in the LMC Truck catalog. Is there anywhere else I could look? Do those exhaust resonators work or do they make it sound too loud and anoying?
