hmm, i might be running what your asking.
CSL headers (euro Z4m) to SS catless section 1 to RE Xpipe to a set of race mufflers.

RE Xpipe def bolts up to oem mufflers, as mine bolted up to the OEM pipe before the swap, does the SS s1 bolt up to your USA headers? beats the hell out of me, but i would probably think so..

Nfi about your mufflers , but yeah its pretty loud. and disturbingly so if your not in the right band.
