There are endless videos on Youtube of the Race catback. LMR, AM, and CJ poney parts are to name a few that may also have before/after.
To the OP, no loss of power and in your head.
Like others have said, it is a little larger and from the side angle I believe it is more of a 45* angle. That said, I can't believe what the PP1 part costs being that it is just molded plastic.
Both AM and LMR have full MBRP catback videos with the H pipe that is supplied with the kit. I would imagine the X is going to be a little less deep and a little more high pitched/raspy on the top end.
Do you have any other pics or possible to paste a larger version of these? Any damage at all to the tips and does is come with all clamps and hardware?
