H pipe installed and dyno'd

[jng2985]

jerseyjoe and myself both had After cat JBA H pipe installed, both of us had base line dyno pulls and after install pulls.

Difference's
Mine - blk 13 brembo, drop in K&N filter, borla S, resonators deleted.

Joe's- grabber blue 14, roush AB's

Pulls were done on a mustang dyno.

Best 5th gear pull for me before install was 346lbs and 357hp...After install and damn near 20 degrees hotter I ended up loosing 10lbs and 9hp..? temp?

Joe can chime in and post his number and graphs..


best of the first 3 pulls

Hard to hear any difference in the video's but it did clean up the exhaust slightly, but other than that same old sound..

I also did 2 1/4 pulls and before Joe posts the awesome video of the second one.. The first run was 13.1
