How much performance can I expect
I have an 06 C6 Z51 with an A&A kit. I'm currently at 512 RWHP and 478 RWTQ @ 10.5#. All else is stock accept the kit. What can I expect to get after I install AR longtubes with high flow cats and x pipe. Keeping everything else stock. Ofoucrse I'm gonna go back and get it re-tuned once installed. I just want to keep my expectations reasonable. Thanks.

hi Boat Racer,
I think you might have answered one of my other threads but did you see a drop in psi as a result? Thanks for you feedback, we need to meet up sometime. I'm in SJ and I see u're in Gilroy.

Howdy neighbor!! Yeah, I did respond to your other thread. I did not see a drop in psi as a result of the long tubes. The dyno psi gauge read the same before and after the header installation. Then a few weeks ago, I finally installed a boost gauge and it reads the same as the dyno gauge (10 psi). I have the Corsa Sport axle back exhaust and mufflers and that is a 2.5" system so I went with the ARH 3"x2.5" reduction X-pipe. Maybe my 2.5" Corsa cat back is what is causing the restriction and keeping the boost the same???? I just don't know and since it runs great, I'm not going to worry about any more. 
Let me know the next time you are down in Garlic country and we can try to hook up.
