Ordered this AFE tube to replace the stock pipe. The stock pipe boot at the turbo blew off on my way back from a camping trip and I wanted to replace the boots.To my surprize this replacement pipe did what they clamed it would. It made my truck run better,faster spool and to top it off I saw a two mile per gallon improvement on the highway.

I read a lot of intresting ideas about this product and a lot of people don't belive this product will do anything for the motor, But don't belive that people just don't know or are ignorant. As soon as I installed the new pipe from AFE there was a huge difference less bends thicker and the coating was amazing started the motor I could here a little more whistle and throttle response was quicker less time to spool up and the motor just was smoother. I think anyone trying to upgrade parts on their motor should invest can tell the immediate difference
Well worth it!

I installed this on my LMM along with the Bladerunner and Stage 2 Intake from AFE and let me tell you somethin, DAMN! I cant vouch for the dyno number they claim (16 hp, 49 ft lbs) but I do believe it. Money well spent! Thanks again XDP.

Good clean pipe. Install wasn't bad. The pipe is quite a bit bigger than stock. Nice clean powered coated finish!

I upgraded my total exhuast system prior to deploying to Iraq. I noticed that my engine had a slight surge while at idle afterwards. After researching the problem I discovered that replacement of the stock Intercooler Tube was a must. I purchased this product while deployed, XDP thanks, and along with a new exhuast manifold for the driver's side two things happen. One...the engine surge went away. Two the truck has more throttle responsive and more power either at towing or daily drive. Installment took 1 1/2 hours. Great product here offered by a great company. Thanks XDP.
