stock ls2 with zo6 manifolds and cat only
my 06 ls2 m has just k&n cai, zo6 exhuast manifold with the cat converter attached only and rpm lvl5 tranny. I do have the zo6 3in H pipe as well as the borla system h pipe back but my borla system fits the stock ls2 exhaust witch is 2.5 in? well any how Im curious if i would lose power if i have the axle back mated to the 3in zo6 h pipe. Atm I just have zo6 manifolds and cat converter and she's fairly loud.. kinda sounds like a nascar. I was told Im losing alot of power with that set up because lack of back pressure. Car sounds failry good ask me. I ran a best time of 12.32 at track with 115mph with a 2.05 60ft 1/8 mile at 91mph. Another thing my et ran from 12.3-12.9 but yet my mph and 1/8 mph are really close like 114-116 and 89-92 and thats with 60ft of 2-2.2.. o and fyi car never had a tune

I have a 05 A4 with the entire Z06 exhaust. When I went to the track with it (complete Z06 exhaust open butterflies & CAI only mods) the car ran 12.3's & 12.4's with a 1/8 mile of 91 and change, my 60 ft times were all about 1.9x So you are in the ball park.
My problem was that the 3" pipes were banging around causing the knock sensor to pull timing. So there is a bit left on the table with your current set up.
My car's performance really came alive once I installed a fast intake and got it tuned.
good luck!

You should see it on the dash as the low tire pressure indicator will be on. Some of us who use drag radials have purchased two extra sensors and placed them in a PVC coffin made with 3 inch pvc pipe and two end caps which we fill with 28 lbs of air. We also purchased a tool that allows the car to re-learn the TPMS.
