I put a Diamond Eye 4 inch SS turbo back exhaust on my truck and really like it. Exhaust is fairly quiet untill you romp on the pedal. Even at 120KPH at just over 2000rpm on the highway, there is no annoying drone.
:U:

The smarty doesn't give bad mileage at all. Not sure where you heard that? WELL, except that ALL, yes all programmers of any kind will result in a loss of economy if you put your foot in them.

I get 550 miles per tank around town with my big tires and the smarty set on 2.

thats good to hear. how many gallons does your tank hold?

Its a long box so I think if I convert it correct it is either 32 or 35 gallons I can't remember - it's 135L if that helps.

my aem intake sounds Awesom. The turbo is really loud and the intake pipe looks good also

dalton do you have a pic of your aem?

what do you guys think? cat back or turbo back? cbrahs told me to get turbo back, but why? is there a reason?

turbo back, you will kick yourself later if you dont

but whats the difference?

about a 5-6 hp difference, turbo response and egt

alright. does it make the turbo any louder? as mentioned befor i want as much whistle as posible without going twins
