  • i have 1985 w a new 1993 7.3. 5star auto c.6. d.60 w 3.5 strait pipe it will pull w the new stuff.

  • @Xx69roadrunnerxX Tuned strait pipes, regulare ones don't have enough backflow, I/E less hp, fuel milage, and tourque. But your right, no muffler means more of everything :) Tuned strait pipes actually give it more of a rumble sound too >:)

  • Hypermax sounds better for sure man.

  • i think he means 1100 ft lbs of torque after it goes through the transmission and you multiply it out in low gear and then multiply it through your differential

  • Sounds great!

  • It would prolly take more than 1100 ft lbs to beat a fucking gt500 dude, my 99 cummins is over 500 hp and 1200 ft lbs, I wouldnt try a gt500

  • @kawirider206 yes it is, I saw it on the dyno, and it beat a gt500 on the track

  • @wignigeater  Fuck man, I bet its nowhere near 1100 ft lbs

  • @northeasteg6 I'm getting a 1984 ATS turbo 6.9 making 1100 FT LBS of torque to the wheels...it's 4x4...decked out all the way with only 90,000 miles for 2500, it's faster than most cars and has stacks, can't out beast stacks, lol

  • @IHDiesel436 i just got a 87 6.9, quadcab, duallie with 192k for $900
