I just thought id take a moment to comment on some mods ive recently done. I think did things in the wrong order but live and learn. First thing I did was get the PPE. I was cheap and got the economy, but I can run level 3 which is max for tranny health. This mod is a well worth while mod. When the turbo gets going my truck really took off. One problem was turbo lag. Secondly I bought an 4" MBRP CB exhaust. Performance gains were minimal, sound was a bit disappointing. Its pretty much the same as stock just a slight bit throatier. Lastly I put on the AFE Bladerunner mouthpiece, this really brought the whole package together.

Hindsight; I should have started with the MP mod. Turbo spools quicker and whistles louder. I should have bought the ppe standard or efi live because I could have grown into them. As far as exhaust I think the 5" would have looked and sounded better, but 4" is fine for now. All in all I am happy with where im at but I kinda feel like performance mods are over for me until I upgrade the tranny, which isnt happening anytime soon bc of $

If You Get Rid Of Your Cat. And Do A True 4" Exhaust You Wont Regret It, It Will Wake The Truck Up And Flow Much Better.

I think you have talked me into it. Ive debated it bc of emission laws/check engine light, but I think I can clear any possible codes with my tuner and I also believe that I may be exempt from standard emissions testing. I was talking with worker from dept. motor veh and he stated that diesel pickups registered over 8500 lbs and less then 10000 are not subject to emission tests, but a cat is still required if it came stock on the truck. So maybe I will take my chances

Every truck is different with the CEL, but most of the time it's not a problem, and it's a soft code so it won't affect how the truck runs at all. You can just clear it when you feel like it. I can get you the MBRP front pipe if you're looking for one, so just let me know if I can help!

I just put on a 4" mbrp cat back with a cat delete pipe and afe bladerunner today. The sound in night and day compared to stock. I think the front pipe is what did it. Not to bad to install, just have to fight the cat a bit. I took the mount for the cat off the trans, a bolt and a stud, then proceeded to muscle it out between torion bar and the frame. I would highly recomend a front pipe, money well spent. No cel either.
