[HWYSTR455]

I've run both, the Xcelerators and the Super Turbos, and the Super Turbos are a notch quieter, especially at WOT. Run the largest case you can, the shorter ones are louder.

Can't remember if it's the 20"s or the 23s that are on the 442, but it's pretty dang quiet. Perfect for that car. No drone at any RPM. The Xcelerators have no drone either. (I run X pipes on all cars)

I prefer the goerich's, the crackle they have is something I really like. Very unique sound, haven't heard another muffler that sounds like them.
