How did it go @Slayer? My project tonight is an Alpha Variable.
I only removed the panel half way. It will flex just enough to remove the oem exhaust. I installed a BMS black ceramic with an extended rear pipe. By doing the extend pipe it transfered allot of the sound towards the back. It actually sounds much better. The BMS has an aggressive sound, so transferring it to the rear works great. Overall time without the rear pipe it was about 2hrs.
