Alright. Besides the gm ex. manifold that is posted here with 4hp gain. Has anbydoy tried the pacesetter header? Or the Cobalt addictions manifold (looks homemade tho). I've had the pacesetter on both my cavalier motors, 2.2l, 2.4l, and had good results with both.

But the CA is nice b/c it bolts up to downpipe, and can build/buy the mid pipe. etc.

Any input, dynos/1/4mile times would be great!
