well i have 275s but i don't think there's that much of a pressure difference. 30-32ish on the street. 12.5-14 at the track. very good tires!!!!!!!!!!!!!
You need to get rid of, that O/R H pipe and put on a high flow catted X pipe. You'll see a difference, in your time at the track not much but it's a start. Maybe as much, as a tenth of a second faster. X pipes scavenge exhaust gasses better, an H pipe is more of a balance tube and not that equal a balance, Mike. SCT Tuner.

What tires are you talking about, the nittos or BFGs? i have the nitto 555R haven't taken it to the track yet, isnt 12.5-14psi a little low?

People don't buy mid pipes for power, they buy it for sound.
