Has anyone installed a set of the clamp on muffler that are the bullet style. Just wondering if you lost any power and do they do a good job in quieting the motor down?

Do anyone know how much they dampen with very little water flow? I have a very small water dump at the end of my pipes - maybe 1/3" x 1/10"

Looking for 4.5" clamp ons.

Since I'm Hi-jacking this thread - in my case a supercharged 509 with 850HP.

With that power,You will see a small drop in RPM but any muffler that actually works is going to have some type of performance loss.

The Gibsons Clamp On's will take the bark out your 540's with minimal loss of performance. We have great pricing on all Gibson products!
