kinda dumb question:
My sister did something to fuck up my exhaust, now its loud as hell. anyone know of any good mufflers that will yield at least some performance gains but will still be relatively quiet? this'll be going onto an acura vigor

 

A muffler will do little for you, do a cat back or nothing imo.

 

why would you want to make your car loud? Arent they more luxury then anything?

 

Vigor? Luxury?? hehee....

Acura no lnoger makes the buzzy little 5cyl anymore. Pretty sad is Honda makes an engine and discontinues it.

But back to the point. Dynomax ultraflow stainless will be your best flowing quietest muffler. HOWEVER, on a small displacement engine even a hole catback will only net you 3-5 hp IF that....
