The "Monster" from Flowmaster
1 of 1 found this helpful Haven't driven yet to see if they are going to produce interior drone, but absolutely love the crisp, deep note these mufflers make. I'm a little old school and didn't want the chambered sound for my car, so I chose this absorption model. Very happy with decision so far because they truly live up to their "monster" name.

Awesome heads
Heads are beautiful... ports and combustion chambers nice right out of box.. Quality product.
