I am looking to add an x-pipe to my M and currently I am running on Vanguard Ti and love it very much. I wonder which x-pipe (without any modification; eg, cutting, welding) I should get if I hope not to get too much louder. ( i live in a townhome complex which 90% of the neighbours are retired(age-wise) and I don't want to put myself in the situation dealing w/ their complaints)

Any input would be appreciated. Thank you guys!!
