Meh, they look kinda small on the 695 with one on each side. On my S2R1K they look really nice in the shotgun style. Without the baffles and cat removed on mine, they are "feel it in your chest, set off all the car alarms, crying children, pull in the clutch when you pass a cop" loud. I'd say a 20 minute ride without hearing protection yields ringing in my right ear for several hours, so get the baffles and make your own choice. I usually leave them out... >

I'm not sure what the 695 ECU will think of them, my 1K has no problems. Plugs read normal, temps are good, mine had popping on deccel with stock exhaust which didn't really change with the Mivvs.
Last, PJ is excellent to deal with. I had my system at my door about a week to a week and a half after ordering.
