Alright my car has the 306 cam, pacesetter longtubes, 3 inch x-pipe duals, no cats and now I need mufflers. I was looking at getting dynomax 3 inch race bullet mufflers model number wlk-24222 or 24219 from summit racing. These don't have any material in them, correct? Will these at least reduce the noise somewhat? I don't want to buy them and them not do a thing to reduce the noise. I want to at least be able to notice SOME noise reduction from what I have now. Also if there is no material in them how does it reduce noise? Thanks for any help.

 

I have 2 18" bullets on my car with the factory heads and cam and it is still loud. They do have some muffling material in them, but they are still freakin loud at WOT. they would probably quiet your car down some, but i heard spintech and magnaflow make some good mufflers that might help your application.

 

I'de get spiral flows or flo-pro tristers. I love how my spiral flow's sound.

 

any straight-thru muffler wont muffle as good as a non-ST but youll sacrifice a little bit of flow for less noise

 

Ya they will be loud...but they wont kill anypower like a reg muffler would. Glasspacks quiet a car down quite abit but im not sure if you would like the sound...could always try it though they're only like 20 bucks a pop.

 

magnaflow 4x9" straight through mufflers, makes a huge improvement on sound.

they're stainless, not too $$ and are as thick as a bullet muffler is
