I have a Corsa Touring series and the in cab noise is all but absent in town. It is a straight through flowing unit with a patented porting process that cancels the resonance. It really has a great sound when you romp it. Dead Silent in the cab at highway speeds. You are getting quiet on the inside, and great sound on the outside with all the flow you need. If you shop hard you can get one for $650.00 delivered. Just make sure you go to Corsa's site and get the correct p/n.

The FloPro model you want is the 2503. That's a dual in and single 3" out.

They offer another one that's louder called the 2504. That's dual in and dual out.

FloPro Big Oval

Hope that helps you.

Mr. Sandog

Are Flo-Pro mufflers a straight-through design, or are there baffles of some sort?

i Had the same problem. the first time i put a magnaflow duel in and out 3" muffler and the cab resonance was really bad. so the second time i put a big SUV magnaflow single in and out 3" muffler and it took almost all the cab resonance away.
