bweeks do some reading bud.
diamond eye or mbrp 4 inch straight pipe.
if you have a cat and live where you need to smog your truck obviously get cat back.
if you dont have a cat, do 4 inch turbo back. i have to smog my truck every 2 years and i pass every time with 4 inch turbo back. my truck obviously did not come with a cat.
my dad runs the 6637 intake and it flows great and filters extremely well.
i have the s&b intake.
if you have to smog your truck get the s&b, its smog legal. if not save yourself some money and just get the 6637 kit from riffraff.
and do not, i repeat do not get a programmer.
they are lame, seriously who wants 3 crappy generic tunes that take forever to switch between.
get a 6 pos chip from php, gearhead, no limit tuning, tony wildman.
or the hydra from php.
you will get way more power, and your truck will run smoother and cooler (egts) compared to a crappy generic programmer (edge, superchips, hypertech are generic programmers)
and gauges too, isspro or autometer.
or if you want fancy edge cts monitor
