^I'm sure Tom or Nick would hook you up with a catless setup...but I guess my question would be why would you want to...the high flow cats they use are a minimal hp robber and you can always run cutouts to gain that totally roudy sound everyone wants. With no cats, you will have to deal with the "gas" smell, fail emissions, and probably have some interior drone.

I'm just saying....I've been there on both my TA and TBSS and if you can get high flow cats that don't restrict on power, I'd personally rather run those, especially on something I'm gonna drive alot. If its just a weekend car for you, then I guess that may be a little different.

I've got a wife to deal with, so I don't have a choice.

^Andy, do you have any sound clips of that....That's basically what I was thinking about, but it has to be a wife approved sound level so I need to hear it. The fit/finish is great as uaual from you guys!

Only our 427 video,I to will be making it wife friendly.

May also install the 3" dual in dual out up front...this is how I do the Vettes.

If you look at magnaflow production exhaust for the camaro you will see they do it this way as well.

We have gone over 550whp with the g8 with stock axleback dropped it and picked up 7 whp ..

Have you done a mpg comparison yet? I'd be interested to know what effect this has on gas mileage.

I have not as of yet...can't keep my foot out of it long enough to get a fair comparison...but generally speaking I would expect a little better mpg with headers and CAI, as you are improving the efficiency of the pump (ie motor).
