And then I see MCM and The Skid Factory and wonder how the heck they do it.
Lemme tell ya, even as an Aussie I wonder too

Wow great work!! Good job powering through all the fitment issues - I bet the side draft gurgle is all worth it. 
Thanks Alex! It has noticably more punch when on throttle, and the burble/gurgle you get when idling down to a stop is absolutely incredible. Once I get the manual in, I'll do a vid with all the sounds it now makes! Which reminds me, I need to go through your thread again for tips on the swap!
