New 4 inch exhaust
I guess there not the best pics but here it is.
My exhaust
hooker shorties
true 3 inch y pipe to 4 inch single.
I am running a spin tec muffler in the back and a dynomax muffler where the cat would be. I dont have pics with the second muffler in. The pics just show my cut out.

Sooooo, cool?!?! I've heard of people with a single 4" system.
But 2 mufflers?? More back pressure, or for emissions?? How does it run? Did you notice a huge difference? I bet it sounds awesome.

Havent started it up yet. I ran two mufflers because I know the spin tech one is loud. The dynomax muffler is nothing more then a glorified glass pack. Its there 40 dollar "race muffler" So back pressure should not be an issue. I want to keep my car as quiet as I can seeing that I am going for a sleeper look. Hence exhaust tips will be hidden like a stock car would.
