Is it an LB7 or LLY? That is important to advising you.

First thing I did was straight pipe it.the EGT's will be cooler,and the sound and MPG is slightly better.Getting that 3.5 inch opened up will hold you for a mid level tuner..I run a PPE and the 3.5 does fine,I ain't saying I couldn't benefit from 4inch,but hell I am tight and old fashioned...sometimes.:drink

Like mentioned above let us know if it is a LB7 or LLY. That makes a huge difference in what products will benefit you.

Sorry its a lb7. When you say straight pipe it just cut the muffler out and throw a pipe in it that all there is to it. Sorry to ask stupid questions but like i said new to diesel. Thanks
