hey guys i have a 305 tbi and i have TES headers, gutted cat, 3 inch pipe and a 80 series flowmaster muffler. at idle u can barley hear my car. it idles around 550-600. does any1 know of anything to make it a bit louder? and keep it legal cause i don't wunt open headerrs

 

get a 2-chamber flowmaster muffler (I think they call it 2 series).
I have a 1989 2.8 v-6 engine and it's pretty loud, even at idle.
That's the only upgrade I have in my car.

I agree,...go with the 2 chamber....it sounds really nice. I love the way people turn their heads when you let it open up full tilt.

 

I like the Hooker Aero Chamber, not the loudest at idle, but soon as you give it some gas it sounds great. Sound clip is in the signature.
