I think kaji335i is on to something here and i agree with Shiv we have to protect the inviroment. If we look at the supersprint set up with metalic cats some way back and unrestricted dp we get the best of both worlds. As i see it with ur. dp you get rid of some unwantet backpressure caused by the cats in the dp plus a faster spool up time and less heat in the engine
room. From what I´ve read about the s.s. system there is 24hp gain with the full system (ur dp) and only a 10 hp gain with with catback (stock DP)
