Based on what I'm seeing, I'd agree that you're right on the money with that part number...but that price is stupid. For that price, if you haven't already bought all the other dual exhaust goodies, you'd almost have to consider just going all customs front-to-back.
I know lmao. My current solution looks like someone just went to lowes and bought a small bag of hardware and some HVAC hole strap... well it exactly looks like that lol... It works but I mean, there is noway i'm going to leave it like that.
