Hey guys, put a straight through exhaust on my 2012 D40 a couple of months ago, then a few weeks ago had a new turbo installed as old one carked it. before replacing the turbo i was really impressed with the exhaust sound, had a really nice note and such after putting new exhaust on but since I've had a new turbo put on the noise is nearly back to what it was with stock exhaust and muffler, does anyone have any ideas why this is the case? was it the old turbo on its way out or is there anything i could do to get that sound back (upgrading pipes/intake etc.)? any ideas would help cheers.
