max exhaust size
so i know my exhaust is fairly large but i lifted my car and realized its HUGE. the smallest part might be 3.5 inches. it has an 18 inch resonator thats like 7-7.5 inches wide (o.d.) it sounds awesome has more of a raspy sound to it. but still i wonder how there can be any back pressure ,there arent any cats and the whole system is quite custom, some one even autographed with a stick welder. what are the rest of you running on your t2s?

I believe mazdatrix says no more than 2.5 inches, or you hurt exhaust gas velocity.
They have an exhaust narrative section that summarizes what you should do.

Ain't THAT the truth! I swear that it's glad that my shop was block from the local airport.... I was running 4" down and out to a Apexi 115 Dunk and GAWD....
Bad-*** for the top-end, though
I can MAYBE see 2.5-3, but not much more.
Any idea what your down ID measurement is ?

How big is the pipe that attaches to the turbo?

The way your exhaust moves around like that, I'd say you need new doughnuts on the hangers. Speaking of which, is it hung properly to begin with?
