Flowmaster 50 Series Big Block 3" Dual In 2.5" Dual Out Chambered HD Muffler. The Super 40® features Flowmaster's Delta Flow® technology. It's larger case profile provides the best of both worlds of performance and sound.
If your putting this on a 22r it’s quiet... I really wish I would have gone with a super 44. On the positive side it has a wonderful deep tone. Definitely makes that little 4banger sound better.
