straight piped
hello. There is a young man where I live that has an 05 4x4 crew cab 6.0. I have started talking with him about his truck. He is running some kind of chip.Not sure of the brand. Any way He just put on a 5inch turbo back exhaust system. Comes out just in front of the rear tire. Man this thing sounds cool. I was surprized when he said he wasn't loosing performance because of the lack of backpressure. I'd love to here your thoughts on this one. Thanks in advance.

How does he know he is not loosing performance, did he dyno the truck before and after or is he using the "I spent money on truck, therefore there is no way it could not be faster" method of testing ....I know it works for me...the more money I spend the more I am convinced it is faster 
Did he buy it form MotorHaven ...wait is he a member of FTE...if not start your recruiting....

Well the ignition claims up to 10 percent, the cam is good for 7-10 more horses, the pipes should give 3-5 more, and the air breather should give it 2-4. On a bike that was already making 75 hp. that would equate to 98.5 hp.
To bad it doesn't work that way

EBP sensor is in the left manifold all the way up front before the turbo. Low restriction exhaust doesn't seem to hurt it. I'm not saying it won't shorten the life of the turbo I'm just saying that the truck performs better with lower restricted exhaust. Just my opinion I guess
