The Strömung 3" stainless dual-tip catback has no resonator but does suffer from the same necked-down flange to mate to the stock turboback. This can also benefit from a true 3" flange welded in its place. I'm happy with this catback although fitment is tight at the rear diff to maintain good ground clearance. Kartboy (or similar) hangers are highly recommended with the Strömung 3" catback.

If I were in the market for another performance catback, I would look for mandrel bends, stainless construction, and minimal bends in the tubing for a straight shot out of the muffler can. Look at the improvements made to many late model OEM exhausts over earlier versions - simple design changes to try to straighten exhaust tubing for flow improvement.

The hush is a quiet system, the rough neck design can be fixed easily by calling MPJ Performance and ordering one of their adapters (and yes it does bolt up to the stock downpipe).

The hush won't start getting loud until you remove the downpipe and resonator, other than that it is a very quiet system that gets a bad wrap sometimes for the catback-mid joint and the flow, those can be fixed too but it sounds like you want to have a sleeper exhaust
