Hey guys, i have RB 3" DP that normally comes with the RB Full turboback exhaust system, i was wondering weather or not the length of the DP that comes in the package is the same size as the stock downpip. Im thinking of bolting some cats back up and im wondering weather or not its going to fit, thanks -alex

 

you can't bolt the stock cats up. Maybe an aftermarket 3" cat but I'm not sure. I think the dp is made specifically for the racing beat system.
