this chop shop stole my secondary cats/resonators and i want to replace them. you may ask why? they did such a bad job, on start up there is a nasty rattle sound, a cheap sound. so im looking to buy the cat system for the drivers side and then maybe a cat back system or maybe a muffler delete. or if you guys know of a cheaper better alt. than replacing the system let me know. the weld they did is so tacky!
