What are you doing running around with the cut out open testing gas mileage? ROFL!

And where are the dyno numbers from the new Flaco tune?

 

They were slammed on Monday was going today then I got called into work Part-Time @ $27.00 an hour you can't turn that down. Maybe tomorrow I can dyno. And I might be doing some driving with the cut-out open I'll never tell..

 

Do you guys know if a downpipe would void my warranty or not. I called my dealer about the intercooler piping and they said I will be ok. Also should I do one with a cat or no cat? I don't mind the smell and all they do for emissions here is plug the car in for codes. Thanks in advance

 

Do your small part for the planet and use a CAT. You will never know the performance difference but the planet will appreciate your concern.

 

Will do. Bill over at hahn told me I wouldn't even see a difference unless I ran a bigger turbo. Which I won't do because the warranty is too good Every car ice owned I ran a cat on so I mind as well keep going. Thanks XXL

 

I don't think you'll notice a permanent difference in peak HP due to the learn down and turbo limitations, but I think you'll see a difference in throttle response and power under the curve. Also, you might see a permanent HP difference if you get the stage tune because there is no learn down.

XXL, have you seen inside our stock cats? Looks pretty restrictive to me. I can take pictures if you like.

 

No pictures necessary. I know what a CAT looks like. BTW, I didn't limit my response above to stock CATs.

 

I do have the stage tune from GM. I think it says it in my signature too lol.

 

Riiight. I knew that. Guess I should have checked.

XXL makes a good point about high flow cats. I wasn't considering that.

Here's a picture for you anyway, since I know you like those.

 

Aaron SS I was talking about a Random Tech Cat on it in a 3 inch size.
