The headers are 1 7/8 with a 3" into 3.5" Y-pipe. Suspension is all BMR adjustable.
Here is the before/After dyno. Dyno done in 3rd gear locked converter.
Before is lid,Magnaflow,3.42 gears and fully tuned
After is the headers,fully retuned.
Guess the 1 7/8's don't really hurt the midrange

NIce start but your gonna need a little more than that
Nice gains from just headers and a tune. When does the cam go in ???: I got a set of UMI lower control arm relocation brackets that I no longer need. They helped my car hook real good. Let me know if you want them.

The ARH fit nice and are alittle struggle to get in. I also cut pieces off my subframe to give more clearance.The Y-pipe fit's perfect.
