Default What size headers with my P1SC?

I'm running a mild P1SC setup.. Mods in sig.. And I'm debating if i should go with a 1 3/4" or 1 7/8" header.. I doubt I'll be doing any other mods as my goal is only to be high 11's and around 500whp..

I'd go 1 7/8's, helps get every bit out.

I have the good ole Pacesetter 1 3/4. I would go with 1 7/8 if you have the extra cash.

Exhaust flow is very inportant on a boosted motor. so I would get the 1 7/8 (I am running 1 7/8 kooks) But if you goal is only 500rwhp 1 3/4 will do just fine. But if you think you might ever turn it up more I would get the 1 7/8.

Dont the 1 3/4 help the torque some? I'm running 1 3/4 & had no intentions of changing my exhaust set-up for my D1SC build.

How high do you plan to spin the motor?

I'm getting 500HP out of my stock exhaust manifolds. Belt slippage and injectors maxed at ~6000 RPM.
