So i've heard Long tube headers add a good amount of HP plus torque, is this true? is it worth it?
I wanna get the long tube headers, x-pipe with highflow cats and a cat-back exhaust, so the whole thing..

I currently have a JLT intake with a SCT tuner, i have delete plates coming in the mail now.

on a N/A car you'll get 20ish whp from a set up like that IMHO, better to go catless for a added bump, IMHO not really worth the cost

If you are going to stay with cats, go with shorties and reuse your factory catted mid-pipe. IMO the biggest gain going with long tubes is getting an o/r mid-pipe deleting the cats.

Whats an o/r pipe? I can't do catless, cause the car would need smogged and I wouldn't pass. So long tube headers with high flow cats on x pipe and catback exhast is no good really. Or not worth it, I would think so cause it's not stock and it's higher flow

O/R stands for Off-Road aka no Cats.

For LT's w/ high flow cats it really depends where you live, for instance I live in GA and our emissions consist of if there is a check engine light on or not (practically). I am not sure about Cali, hopefully some will chime in and help you with that.

Good luck.

if ur in cali stay away from changing the cats unless u know someone that can just pass u.

That should be a great combo.

thats what i was thinking..I might go catless now, atleast for the year, the pypes offroad xpipe is adjustable i think, so it can allow cats or not, so in a year if i have a problem smogging it (which, if there is no check engine light being thrown, it should be fine) then i'll buy some cats and install them..

I also know someone that does smogs so he should be able to hook me up if i slip him a couple bucks.

If you dump the cats, get a fresh tune from Bama, Brenspeed, VMP or whomever and have them shut off the O2 sensors. That'll keep you from throwing a CEL.

oh i'll deffinitly get a tune because i'll be getting the full exhaust system..

If i get the O2 sensors turned off then wont they know at the smog..and doesn't the pypes off-road x pipe have slots for the O2 sensors..

I'm thinking about doing shortys now, cause they are alot cheaper and would provide a little more HP then the long tubes providing more torque.
