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.

anyone

What size engine are we talking about?

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.

it is a 502 that is bored and stroked to a 540 running roughly 700 hp

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!

I've got a whippled 509 in my Ultimate Warlock 25sxt with
the gibsons and they work great! can still hear the stereo
at 95+

I am trying to get it below 88Db as the DNR like to pull me over and give a ticket for $175
