NovaJoe, how do you like the "x" pipe. I have 2.5" Ultraflos with an H pipe.It sounds good but the X pipe got me curious about the power & sound vs the same combo with an H. Any thoughts?
I actually put the x-pipe on because I read about the power increases over an H-pipe. The Flowmaster kit I have came with the H. The sound didn't change a lot because of the cross-flow type muffler. I think the sound would be more dramatic with true dual exhaust. I still like the sound though. Don't know if I picked up any power 'cause I don't have a before and after comparison. Hope that helps!!

My 74 Pro Street Times

Here's my latest time for my 1974 Nova Pro Street. The car dyno'd at 318 rwhp and 355 rwtq. That was before the valve springs got replaced. Car has more torque and hp now!

My best 1/8 mile stats so far:
60 foot: 1.817
ET: 8.141
MPH:87.04

This should equal a 12.76 in the 1/4 mile.

Stats on my car:
72 396 Big block
700R transmission
8 3/4 Mopar rear with 4.56 gears and spooled
Tires are Mickey Thompson Sportsman Pros 31 X 16.5 X 15
Holley carb on top of a Weiand Stealth intake.
Hooker Supercomp headers with dual exhausts that exit out in front of the rear tires.
K & N air filter and flow through top.
MSD 6AL with the 7,000 chip in it.
Car is back halfed, roll cage, and ladder bar setup.

I should be able to get a little more out of it when I put slicks on it and open the headers. Hopefully break into the 7's since I still have a little spin with the Mickey Thompsons.

:D
