+1 Robert...I just installed the SPT Catback, SPT Short Ram and the heat shield a couple of days after flashing Gabe's R29. Noticeable difference in power/spool. The CBE sounds great. Not too loud, just a nice rumble. I'm not sure I like the sound of the BPV now though. Maybe I'll get used to it. I couldn't get the MAF on without cutting some tape off of the wiring harness. Also, the MAF doesn't sit flush. The screws bottomed out before they tightened the MAF to the short ram. Maybe that's causing the excessive BPV sound. I'm either going to make a gasket, or I'll grind a little off of the screws. With the MAF seated correctly, I'll see what that does.
