Could this be the end of the dry vs dry to the tip tailpipe debate? Always liked step tube headers to kill back pulses, they work well, but never gave this possibility a thought. A nice gain in torque is also right up our alley.

No, not totally, but in same subject, i have helped a few members here by getting their ‘collector/tailpipe’ lengths correct. Do a search. Primary tubing is one thing, but collector/tailpipes can be a whole nother.

Btw: Vizard articles are usually a good read, but not always correct. He sure enjoys creating hp or etc ‘break thru’s.’
