Soo in ref to the OP (just to clarify) it looks like you keep the stock x-pipe and add ANOTHER Magnaflow resonated x-pipe after that which replaces the oem resonators???

As someone else said, will a 3inch in/out dual resonated X-pipe work in this space just the same? I'm thinking it will allow for a smoother flow with even less resistance.... if I can find one.

I find it shocking that performance doesn't decrease when going from 3" > 2.5" > 3" again. I would think the bottleneck would definitely hurt performance.

Also, would it get the same results if we would just leave the oem resonators in place and put this resonated xpipe in place of the pinched oem one? Kill 2 birds with 1 stone? Further quiet down the exhaust drone and rasp and improve power? Thoughts???

I'm trying to find the easiest solution for my setup to quiet it down, aside from full throttle and get rid of the drone.
