PLM / CRSX / KiddRacing Race Header installed -- interference with subframe

[ClayMan]

Just replaced my DC shorties with a PLM and thought I'd share info that I wish I had found earlier.

Setup is PLM header and test pipe / T1R midpipe (RSX-S) / modified Apexi WS2 muffler

Everything bolts together, tons of clearance with the stock EP3 sway bar, but is very tight with the front subframe. Under certain engine load conditions, the header vibrates against the subframe and is extremely annoying.

:(

I had this exact same problem with my OBX V2 RH for a while. wound up going to my buddy's shop and banging down a tiny piece of the subframe to give it the clearance it needs. no more louddd assss vibrations anymore.
