What would be the best Header and Exhaust I could get to better the performance of my motor, I am looking for bottom end torgue primarily.

I like what I read about Downey 4 to 1 header. What else is out there and cost?? I'll pay for decent quality/performace but I won't throw good money away buying the "Best" out there unnecessarily.

thx

forgot about exhaust, i heard that you can up to 2.25" exhaust pipe to gain more free flow (good for usage between 2000-4000rpm) something to do with needed back pressure (not too sure) but if exhaust pipe too big is ment for engine running over 5000rpm (red lineling, not a happy place) i ran 2 1/4 exhauist with free flow muffler and no cat. seemed to gain a bit of power

I have 2.25" with a Flowmaster side pipe (just in front of the rear tire). Had to put the cat back in for AirScare and decided it didn't make enough of a difference to take it back out. It sure sounds a whole hell of a lot sweeter when it's out though.


For more torque might I recommend an aftermarket cam or lower gears?
