I installed my Akra Slip-on exhaust with the wireless kit, maddad midpipe and Revozport CF diffuser a couple of days ago. I had no alignment issue with the exhaust itself or the tips, they fitted perfectly! The Revozport diffuser wasn't a perfect fit, and it had to be installed with some work, but it finally enden up aligned.
The sound is intoxicating!! I can't get enough of it!! And pressing the Akra button and listening to the exhaust open up makes my day every time!!
I'll post some pics tomorrow night...the CF diffuser and the CF tips makes my BSM 1M look like a mean mofo!!!
