From everything I've seen about high flow cats ............
You would only pick up two or three rwhp if you went off road.
You see peeps talk about a noticable gain by going to OR pipe.
Of course they do .............
That oem 4 cat pipe is really restrictive ..........
even all the more so if a lotta miles has been put on it.
