I have a 2014 Mustang
GT with Roush Axlebacks and a Corsa After Cat X-Pipe.
I just ordered the Boss Manifold, Airaid CAI, and an SCT X4 with BAMA tunes.
Ive heard the biggest restriction is in the catalytic converters so I was looking at the Off-Road Cat Delete pipes. The Corsa After Cat X-Pipe is 2.75" so I was looking at getting the BBK Off-Road Cat Delete Pipes to pair with them. Does anyone have any experience with these? Ive heard of people having issues with the factory H-Pipe, but nothing on an aftermarket X-Pipe.
Also, is there any more benefit in just swapping in a Lethal O/R 3" X-Pipe? It'd be much cheaper just to swap the Cat Delete Pipes.
Finally, can anyone comment on the sound of an O/R x-pipe paired with the Roush axlebacks? Ive heard its extremely loud? I like the way they sound now and I dont mind a little rasp.
With all these mods, any idea on RWHP and RWTQ?
