Here are my dyno results, before and after runs with stock to O/R H-pipe.
This is definitely a wonderful mod if you're going for sound, since the cats on our cars are already pretty non-restrictive, you won't see much gain HP/TQ wise. My butt dyno tells me throttle response improved a bit as well, only issue I'm having is a "hissing" type sound when I go to 2-3k rpm. Otherwise the sound of the engine drowns it past 3k rpm.
But the mod definitely put a huge grin on my face, can't stop revving the car now.
Only performance mod the car is running is 93 oct race tune by BAMA.
