Thanks it looks like I'll probably go with the MBRP. Is there a big difference between the T409 and the T304 stainless. Also what cold air intake would you recomend?
The T304 is a higher grade of Stainless Steel. Most folks who get the T304 are in areas that have lots of snow/ice/salt. It is least resistant to rust.
T-409 is a lower grade of SS, but is perfect for guys like us in the west coast.
Aluminized will work well and is cheapest too.
Both T-409 and T-304 will most likely outlast the life of your truck!
AIR intakes..... www.afefilters.com John carries them on www.dieselperformanceshops.com

Airfilters: AFE
and yours will be the Stage II Pro-Guard 7
