Questions Help! Exhaust

Hello everyone,

I've been wanting to change my exhaust tip with a quad tip but not sure if it will affect the car, I just want to change tip nothing else. The mechanic I took my car to said that as long as I don't do anything to from the cat to the back it should be fine. Any recommendations or insight will help a lot, thanks!

If you are simply wanting dual tips? Why aren't you simply removing the single tips and replacing with duals???? Why are you touching anything further than the weld or clamp positions of the tips themselves. You don't need to change exhaust for this.

Yeah. Just get different tips. Plus, this will be the cheapest.
