Hey I have a 2 1/2 inch racing beat down pipe with 2 1/2 straight pipe no nuttin to stock turbo II Mufflers. I have stock turbo no ac no power steering, 255 walbro pump. I also have a hks fcd. Inabout a week after i get my car started i wanna put rc 750 cc injectors for my secondaries with a apexi super afc II. And i'm going to be runnin only 10 psi. maybe 14 wen i go on da track.

 

I don't actually see a question...

 

Sorry about that But As you can see in the title. I was wondering if this size exhaust would be good for the set up that i explained above.

 

Just run a 3 inch stright pipe all the way to your stock muffler. Or go dual and run a 3 inch stright pipe all the way to your Y pipe 2 3/4 inch there to your stock mufflers. EXTRA HP there to breath.
