I'm goin to be deploying to the desert next month. i want to know which is the best exhaust system in terms of loudness and HP.

I personally think GMMG Chambered Exhaust System that was put on the 2002 Camaro ZL1 Phase 3 w/Stainless Tips
Includes optional stainless dual oval tips
2 1/2" Tailpipes, straight back, angle cut.
It fits 1982 and up Fbody
the price is around $800.00
Have a look at GMMG's web page down the side it will give you more info and if you want you can listen to the Chambered Exhaust System on GMMG's web page.

how much HP does that system add?

CCCustoms

I’m not sure how much HP it kicks out it must be one of the highest hp exhaust systems because it runs through true dual transverse chambered sections (like cherrybombs) instead of a muffler like the factory Z28's and SS models that have a rather restrictive cat back exhaust systems.

Go with an over the axle true dual exhaust system. The best of all exhaust systems.

Longtube headers and 2.5" duals with an xpipe. The rest of the variables are up to you. For a massively loud system dumping it at the axle with a couple Dynomax bullets works well. Some people say it's too open though on LS1s with the bullets and just sounds like BLAAAAAAAAHHHHHHHHH. Really personal oppinion.
