Moroso Mufflers???
Just wondering how much of a difference moroso spiral flow mufflers would have on approx 6.0L tpi car? How much deeper would it sound? About what kind of hp gains for the tpi? Thought I'd ask since a few guys with 4th gens are running these mufflers and they love them.

i'm running them and they work for classes that require mufflers, and flow very well but don't really muffle anything more than a bullet type muffler.

I'd definately get one if they made 4", but they do not. I've heard them in a true dual system ALONG with Race Magnums and the car sounds great/not too loud. That car was a 355 w/ 13:1 compression, big hyd. roller cam, etc. Luckily they only cost $40-50 so you won't take a big hit if you don't like it. Goodluck!

they're not bad at idle, but when you open up the engine they get really loud.
