the gains between brand names will be almost the same +/- 1-2 hp. the difference is the material and fitment. i know someone w/ bassani and fitment was good, idk what kind of steel they use tho.

What headers are best for auto? REmind that im going for the deep rumble sound

all LT's will give a louder sound, idk if can distinguish between diff brands of LT's, but for a deep rumble the midpipe should be o/r h pipe or prochamber. its easier to tell the diff between midpipe and axle back but more difficult to tell the diff between LT's.

the LT's will make it loud (and increase hp), midpipe will set the tone: h, prochamber, or x pipe, and axle back will give the distinguishing note. if you want the deep rumble i would stay away from the x pipe.

If I've already removed my cats and gone o/r... how many MORE ponies can I expect by adding mid-length 5/8" longtubes?

I bought the Mac longtube/o/r-prochamber combo from brenspeed and love it. The prochamber is stainless steel and the headers are ceramic.
