The JIC-Magic email and send me a nice photo from under a Z with the dual exhaust tips, but is since to be the same muffler that the B&B, they don't say WHAT is the RWHP for the System, but I'm guessing is the same of B&B.
I email back to ask him again about the RWHP.

 

got a lot of 350z messages, just give me time to get back to you! I also carry the Amuse - but keep in mind, they are shipped from Japan, and I do not have any in stock, at least at the moment. I can provide shipping and pricing information upon inquiry.

Thanks
