I will probabably quit at 625-650 at the wheels. since me and my wife both drive the car alot I don't want to really make it something your just fearful of lossing grip at all time ha ha. she got used to our old Z06 which was sketchy at times but I don't want ot get any wose than that.

after the headers I am going to buy ID850's and play around a bit more with power.

if I were targeting 700whp I would personlly spring for the 2" other will say you are fine at 1 7/8's. I mean 700whp is ~800hp at the motor.

I think it was baron or someone like that that did some dyno data. I know at one point I looked at 1 7/8 vs 2.0 tubes on a ~700whp car and there was no downside on that car.

BRcar,

Thanks for the info. However, why do I need to P/N's for the clip and bolt? Won't my parts from my 2013 ZL1 Belly Pan work? Or are they different?

I have 1 7/8" American Racing long tubes. The belly pan has to be trimmed although I didn't because I wrapped the end with heart wrap before putting the belly pan back on. They are stainless steel but not ceramic coated.

I thought high flow cats were a bad idea with higher boost?
