alrite.. i have searched and i have narrowed my choices down to

1. magnaflow
2. Thermal R&D
3. Apexi WS

My friend has the WS and i really like it.... nice and quiet... how much louder are the other two muffler compared to the WS?? i have the greddy SP now, but it's falling apart.... need new muffler soon... clips of the muffler sounds would be great! also, where can i get good prices on them??

btw, can i just get the muffler section?? i have the catback from the Greddy SP... thanx
