just remember if you get long-tube headers, you'll need to get an h-pipe or x-pipe to go with them. the stock manifolds are a "shorty" style, so if you go with long-tubes, your stock h-pipe (i'm assuming you still have a stock h-pipe) will be too long. you can have a muffler shop cut them down to fit, but i'd just go with an off-road mid-pipe.

ok I'm going to look into some headers and a x pipe on american muscle thanks guys

the only long tubes that american muscle has that will fit on an auto are the SLP and those are really expensive

here are a few places that have better prices that will fit an auto

i would suggest getting ceramic coated or stainless steel unless you want rusty headers

i had Mac ceramic coated headers on my auto GT...i picked up around 20 horse from them. Install was a pain in the ***, if you are not mechanically inclined, i would pay to have them done.

LT headers just happen to be one of the most PITA jobs on our cars. At the minimum you have to unbolt the motor mounts and jack up the engine a little. A lot of people just end up dropping the K-member all together to get enough space. Lets put it this way, its not uncommon for the average guy who decides to tackle this in the driveway to have his/her car up on stands for a week.
