Sorry to jump in here, I'm after a Mugen Twin loop for a EK9 and noticed this thread......not wanting to upset anyone else's deal of course, but irf, I noticed you replied on this??
My car gets into Southampton around the 24th of Sept and I want to keep it largely OEM but was going to put a Mugen exhaust and K&N panel filter in and that was about it......only trying to find a Twin Loop!!
I've even contacted Mugen and of course discontinued..........
