I've finally managed to setup the whole 172 exhaust. i didn't decat it because of the MOT,
so i left my double barrel cat with 1 lambda sensor, there is no middle silencer just a pipe and the backbox is a 90 mm slash cut. the whole exhaust bore is 60 mm.
the sound is subtle and deep in lower rpm's-3000, then at 5500- it gets very loud and raspy.
the car pulls much better than before (with standard exhaust) especially in high rpm's.
here is a pic of the end, i'll put up the hole system.

i've tried the decated version and i must say i didn't notice any difference in loudness or strenght so i decided the leave the original because of MOT
