What does it mean when.....? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

One of my exhaust pipes has a lot more air blowing through it than the other side? My truck has felt like it was lacking power a little before I tore it apart. I'm in the middle of re-doing the chassis, I cut the mufflers out about a month ago, the bed is off it, and it is up on jackstands while I finish my step-notches out back. Today I started it up just to keep the engine lubed and I put my hand behind each pipe. Noticed that the passenger side has a lot more exhaust coming thru than the driver side. Why would this happen?

About 2 months before I started tearing it down I did a compression test and everything was within 10psi so I'm totally baffled.

do u have a crossover (x or h pipe)??

67Fleet · 03-10-2007, 05:11 PM

nope, they are running straight from the stock ramhorn manifolds.

thats why. weld in an X pipe (for hp) or an H pipe (torque) then run them through some mufflers and i bet u like the results

Thanks, not sure I'll be able to accomplish that though. I'm setting my truck up to lay frame and I don't think I'll have room to put in an x-pipe.

u can crossover the exhaust at any point between the headers and the mufflers...im sure u can find a way

Do you have the heat riser butterfly on that side?

Yes, I've considered that to be a problem, but it feels like it moves freely when I move it by hand. Maybe it's broken? I've got some Sanderson headers that I'm putting on it soon, so we'll see if that is the underlying problem.
