ouch !!! 53 bucks . ya might wanna look around for better prices. i paid $25 for the same thing , but i did supply my own $13 dollar flange. but that flange should still be reusable when i need to put a new gpack on unlike the resonator flange that was removed. i'm gonna talk my brother into splitting the cost of a cheap harbor freight mig welder and do the rest of the exhaust myself.
