a question, if i change a exhaust (magnaflow), i got a better performance or i need to change all the cat back



any suggestions are welcome

I would buy the whole cat back kit. The pipe size will be larger.Probably sound better. There will be a little performance gain. Especially with the V8 on single exhaust system.
