[argumosa3]

Thinking about doing longtubes in my 99 cobra. Anybody have any before and after dynos or know of anyone that did this? GT or cobra

LTs are more than worth it. Adrenln gaing like 14RWHP from his LTs alone. I added BBK LTs, electric WP, pullys, and a windage trey....went from 274RWHP to 292RWHP. Your 4V should do even better

Longtubes are pieces of *****. Get shorties if you get anything. Cobra's don't benefit at all from headers period bc they don't make hardly any power.













Just kidding...

yep, hotmustang is absolutly right. they are awsome. i already had a mid pipe so the gains i got were ONLY from the long tubes. gained 14rwhp peak and the down low rwtq was even more amazing. at 3200 rpm i gained 26rwtq, but peak tq only went up 3 tq.

l/t = best mod besides the heads and cams.
