I'm running the cxr kit. Bought it 2 years ago and everything worked well til my engine blew. Now i'm built but with the same kit. From manifold to i/c to exhaust.
How your manifold/dp fit to the Master cyl depends on who was welding that day. I lucked out and have enough room for a heat shield. I wrapped my downpipe anyway too.
Things i'd recommend
Throw the gauges they give you away
BOV is ok, but idk how long it'll last.
Cut and modify their i/c pipe on the hotside other wise you get a cluster fuck when running a filter.
Wrap downpipe
Heatshield
DO SOMETHING WITH YOUR PCV
GET A GOOD TUNE
Things i'm running not included with kit.
