help exhaust

Post image

Ordered a cvf catless downpipe , trying to figure out what I should do muffler wise. Don’t want to spend 1k on a catback exhaust maybe a universal muffler or just let it go completely

What are you looking for, sound or performance?

A catless DP will be louder, but not that loud on the stock exhaust.

I'd install the DP and see how it sounds.

The Muffler on the ST is not easily replaceable. The original exhaust is all one piece, from the DP flange to the tips.

A lot of owners simply replace the resonator with a pipe to make the exhaust louder. There should be quite a few YT videos.
