How much do you gain with longtubes & offroad midpipe?

Thats a pretty nice gain over yours... I know I dropped 3/10's off my ET with my LT's and O/R h pipe so the LT's and O/R pipe might be worth it

i know when i put my lt's and o/r hpipe from shorties and o/r hpipe there was a noticable gain. i think it was worth it just for the sound but there is a bit more grunt in it and i know once the exhaust leak goes away (yeah right) ill be able to get some of that stupid power back

I could not say about the off road pipe as I've never had one. I have seen some say that loosing the cats gave them between 1 to 2 tenths in the 1/4 mile.

LT's really help the torque starting at the mid range rpms on street cars cause the longer tubes pull the spent gas away better than shortys.

I would say that your stock exhaust exhaust manifolds are hurting you more than having the cats.

Of cource, it you go to lt's your nice cat pipe won't work unless you have it modified.

I have a pipe like yours and it really is a quality part.
