Okay, I recently replace my cat an the increase in power was amazing so I could imagine what it would be without the cat an resonator, I went to almost every muffler and exhaust shop i could find and the all said they wouldnt touch it, its like people are afraid of working on mercedes, like they have some disease or something. Then i remembered this guy on my has a nova that he finish rebuilding and his son told me that he did the exhaust all by his self, today i asked and he said no problem just get him the pipes and he will weld it on...so me question is when i remove them is there anything that I have to be concerned about? will it cause my car to run rich? or do anything weird that I would have to adjust? or should I be fine??
