you’re on the right track with what you want. stainless will last you a LONG TIME and while it may not make your car any faster, a deep (and more audible than stock) exhaust can actually help you drive, since your ears will become finely tuned and you’ll have no need to look at the tac.
look for something that doesn’t have a CANISTER style muffler. Borla might make something you can use. Look for something with a resonator too…
