My 156 2.0 TS with 2,25" stainless steel straight through silences and racing cat made a nice burp when lifting off, and bliping the throttle.
It also did the occasional bang when I took it to the redline and made a quick gear shift.
But it also had C&B cams and no ecu optimization, so it migth not do it if the ecu was properly optimized.
It runs straight from the cat...the two centre boxes are removed and the rear box is smaller about the size of a cornflakes packet. The rear DTM style (my favs) were picked by me from a selection of rear pipes. NB these make no discernable difference to the sound. The pipe is almost straight and runs high and flat and through the rear wishbone so no kinks. Took a little fiddling with but an excellent job.
There are no problems with MOT but a word of warning, I believe it is 119db so some tracks wont allow it on track days.
I'm not afraid to tackle the exhaust system DIY style, but was just wondering how much it was from LL cheers for that.
I just spotted this on the bay, which would suit the alfa 156's rear perfectly both in shape and appearance, and was thinking about using these or some of this to just switch the backbox on my 156. The original backbox's shape is a right pigs ear of a thing, so it would require some creative thinking to fit universal box.
I want something deep and sporty but not too loud, and doesnt look chavtastic

Its not necessarily fuel that causes over-run popping, its actually the addition of oxygen into the exhaust system. If you've got a small hole in your system, the burnt exhaust gasses (which on over-run can still be fuel rich) are allowed to burn again with the oxygen that is introduced to it. An inlet leak can also introduce oxygen into the system. My Kawasaki GPZ turbo had an inlet leak and that used to sound raucous on the over-run!
