i just bought a set of bbk long tube header w/matching off road h pipe for $200
i currently have a set of mac unequal shorty headers with matching off road h pipe.
i just wanted to know how much of a improvment
these long tubes make over shortys.hp and torque changes?
i using these on my stock short block w/gt40 iron heads and intake. stock cam.
i think i'll gain 2 tenths and like 3 mph in the 1/8 mile .

I doubt youll gain that much. With a mild combo, long tubes will rob power and torque. If you had n2o or a blower, i'd say +3mph is easily attainable with the addition of long tubes.

Cool. High flowing/revving combo's benefit greatly from free flowing exhaust.

![[patriot]](graemlins/patriot.gif) ....With a mild setup, Id bet that the difference in headers is minimal even on a 125 shot. not quite sure how great the drop off will be on the street. ![[burnout]](graemlins/burnout.gif)

Its not the best combo and you MIGHT lose a little power, but its still a step in the right direction. The cam, head work, n2o, etc. will compliment the long tubes nicely. Good buy.

I picked up almost exactly 1 mph or 8-10 HP from stock headers + off-road pipe to longtubes + offroad pipe, no other changes.
