it probably is difficult to get it to sound like a cup car without changing the cams and the intake. i'm still working on that. my point was the sound improved with the cheap headers, and forget the dyno tests, +/- 5hp is not going to make you 1 minute late to work. i believe the problem with the cheap headers is diameter on each tube may be a bit smaller than needed hence the motorcycle type sound.

These are the only headers known to lose power over stock. They have an obvious flaw. Look at the tubing coming off the heads. Notice how they cone down at the ports. This is an immediate restriction. The reason why they do this it the tubing is too small, smaller than the stock headers. The collectors are also junk. They are just 3 tubes welded together. They are poorly designed and poorly built. The first guy to dyno these headers lost HP over stock. No matter the price (even free), these are a waste of money.

what can you say about the aero kit? did you buy it yourself/install/cost? $5000 is too much for me, but if i could get a deal.......
