Exhaust Diameter Question....
I'm interested in a few header systems on my 2005 C6, but cannot find much dyno information on the different brands.
I also know that some header systems are 1 7/8", while others are 1 3/4". On the C6, can anyone confirm a noticable difference in low end torque? I understand a little thinner pipe will increase velocity, and probably low end torque, but 1 7/8" might out-flow in the upper rev range. Has anyone noticed a real world difference, on a mostly stock C6 between pipe diameter? Also, would be nice if anyone has a link to Dyno's for the different exhaust brands.

George the mods I am looking at for my A4 are . Headers, , Corsa sport, Blackwing Intake, rockers and springs, 3200 tourque converter and a shift kit. Possible 75 shot if needed. What do you think.
