x pipe 1/8+1/4 mile gains

[try2catchmy99]

How much gains do I see in the 1/8 (especially because 1/8 is the only track around) and 1/4 mile if I install a off road x pipe with my current set up. My last time was 8.71 with a 1.9 60 in the 1/8. I am thinking about getting one for the ford vs chevy comp coming up trying to find a way to keep up with those darn LS1s
Thanks

Im gonna say about 10-15rhwp/15-20rwtq. I installe dmine and felt a definite difference. The car pulls ALOT harder up top and doesnt run out of breath anymore. You notice the most in 2nd, 3rd and 4th gears. I love mine.

In the 1/4, I lost avg 2 MPH when I put my 17" Cobra replica's on. When I put my X pipe on, I regained that 2 MPH. It was definately a noticable mod and I wish I had done it sooner.

We just completed some rear wheel dyno tests on a 94 Mustang switching from oem H to 2.5 mandrel X. http://pypesexhaust.com/dyno-94mustang.html I would say a 1/10th in the 1/8th mile and 2/10ths in the quarter mile.

The good thing is once you mod your engine even more, that X-pipe will do an even beter job.

I equalled my best time after putting in a prochamber - not exactally an x-pipe, but similar in concept. I had a lot of trouble hooking up which may explain the lack of ET gains. I did consistantly improve my trap speed by 3 mph (best of 95 mph wiith a stock h-pipe to to 98 mph with the prochamber)
