In my opinion the best combination is long tube headers, mid pipes (with race cats or not - your choice) and a x-pipe bolting directly to the resonator. It will still be loud but not totally off the charts. You can still drive it and it will sound stock but slightly louder below 2500 rpm. After that it will get louder fast and above 3000 rpm it will be quite loud.

The most respected types here are MBH Motorsports and Modern Horsepower (MHP) (American Racing Headers). Both are quality headers. The MBH have 2" primaries and are a Tri-y design. These are great with a supercharger and good for NA as well. The MHP have 1 7/8" primaries and have 4 into 1 - 3" collectors. These have yielded slightly better results in the 1/4 mile NA.

Benzworks is the best!!! They have the highest results too from what I've read/heard.. I dont know why more people don't buy them...pretty sure they were one of the 1st header makers and the other guys just pretty much jacked up their design/changed it a bit
