Before I get flamed, I am sure this has been asked. I could not find what I was looking for I just thought I would ask. Thanks guys for your patience.

it gave me 40 peak ft lbs but more importantly moved my power range lower, so it had a much better throttle responce. I have the fabspeed ss 3" exhaust. I love it.

It's kinda hard to do a back to back comparison with the cat-bypass replacement alone. That's because you'd automatically get 1-2psi more boost due to the lower backpressure. So is it the free flow or is it the extra boost that gives you the extra power? I'd say it's probably 75% from the boost and 25% from the flow. If you were to dial back the boost to the same level as before the cat-bypass installation, then we'd have a more accurate comparison.

Thanks Danno, Right now I am spiking to 15 then dropping to 13. So if I got a test pipe I would probably be able to hold 15 like I used to? Just curious if that is correct.

Well if somebody would give me a test pipe my AVC-R would be able to compensate for the gain in boost and we could get a real measurement on the power difference

I have the SFR 3 inch and am thrilled with it. Car spooled up much quicker...I did some before and after dyno runs; power wasn't muc h different with my set up but the car is much quicker now...With your mods I can't believe it won't be a night and difference...It was for me with just simply chips/restricted banjo bolt set up...
