Doug Thorley Short Tube Header DYNO!

blasphemy!

 

That is a hell of a deal! Lucky you man. If I was still paying on my engine build, I would have snagged those up.

 

i know right haha. idk when i will get them, but no rush. Will be updating on here and XRU with the results

 

I know the OP went with some LTs, but the other factor in ST or LT decision is that the 09+ stock exhaust manifold was redone a bit going from a log to more of a tube manifold. I "have read" that the 09+ manifold flows better then the pre-09, but not sure how that affects the ST/LT dyno pulls. I would assume that the deltas in the curves is less, but definitely not sure by how much.

 

tempted to get some shorties if there was another GB offered and see the difference!

 

How much does a 5 pound increase in torque translate to an increase in towing capacity?

just get the long tube's. You DO NOT feel the low end loss with a stock y-pipe. My area (SW PA and WV) is literally all hills, curves, and shit roads and I def have more power to climb these hills now, even in higher gears, than I did before.

Also after you pay for the install of the short tubes their the same price. Unless you get the stock manifolds off yourself and take it to a shop to be welded, but then if you ever have a leak, you gotta take them off again to get touched up since its prob unwise to weld with the sensors in there
