back fire....?

I just got a M2 downpipe and I was wondering if it suppost to back fire like crazy. It does back fire loud but you can heard it and sometime when down shifting it does the loud ones.

Hell yes! Get a mid-pipe and you will be shooting flames! Just make sure you upgrade you ecu and watch the boost.

I think I got a chipped ECU but the ECU appears to be stock from the outside but it boosting 12-10-12 constatly like is suppost to do that no boost spikes.
