Has anyone done a dyno on Long Tubes back to back with the same mods etc??? And what mods were you running??? How much HP/TQ???

 

Here's my before and after complete exhaust dyno (longtubes, high-flow cats, x-pipe, high-flow twin mufflers, tips):

So could be good for 30HP/30TQ?? I have the Bassani which shows around 7HP/10TQ on the dyno so i would assume i could gain 20/20 with the headers/cats.... Hmmmm, not bad for the dollar spent, even though that is a pretty penny!!!!!

Which Long Tubes were they?

 

Is thepawn the only one with Long Tubes and dyno numbers on them??

 

Beefcake has a dyno of his LT's on his truck, but he already had a cat-back pack, and has no x-pipe...he showed minimal gains.

I got the JDM kit just because it was all in one (end to end) and he could install it for me right there. (I don't have time/skills/tools to do it myself)

Beefcake,

If you're out there, can you tell us what gains you saw from Long Tubes??
