Hey guys! I’ll be installing my catless downpipe probably next week and was wondering if there was an adapter or if I need to use a donut gasket for the downpipe to connect to the Invidia r400. Any feedback would be greatly appreciated.

If its a 3" down pipe (which most are) then it should line up just fine. The donut gasket/adapter is really for when you are going with a 3inch down pipe to a stock exhaust.

All invidia products (if same inches) Line up to all other invidia products. I'm trying to get a Q300 right now and have an R400. All I have to do is trade the mufflers, the midpipe is the exact same
