what gaskets to use with Spt v2?

I am getting my spt v2 exhaust tomorrow and i want to be ready with gaskets.. i live close to grimmspeed so i am just going to swing by there.

1. What size goes on the muffler connection?

2. What size goes on the dp connection? i currently have the grimmspeed 3" to 2.5" adapter, am i still going to use this or no?

thanks

Is your downpipe stock? If it is, then it'll use just the stock donut gasket. If you've got a 3" DP, then you'll need the donut and a 3" gasket.

Not certain on the mufflers, but I'd expect them to be 2.25 or 2.5. Ask the shop while you're there; they should know.

it is a 3" hence the adapter to my stock Cbe.
