i have had the synapse blow off on my ms3 for awhile now and i love it. it is a very well made piece. they got an award from sema for the waste gate and blow off valve i believe. i have it in recirc and have no problems. your not gonna hear it from a mile away but i didnt want that anyway. i bought mine for 208.00 with just the blow off valve and 25.00 for the hks adaptor. so all you guys talking crap on it without even seeing it on an actual car can shut up. if i had to do it all over i would still buy it in a heartbeat.
