Brand new, never used genuine AC Schnitzer catback muffler exhaust system. This is originally for the Euro-spec 323ti, but it will bolt onto the 318ti just fine. If you have a 318ti Sport, there are instructions and even a cut-out template for enlarging the rear diffuser to accept the larger tip (or you can just buy a 323ti diffuser and bolt it on).
All AC Schnitzer exhausts are made by Remus and are extremely high quality. The sound is deep but mild - it definitely doesn't drone on the highway or cause cops to turn their heads when you pass yet has a nice, throaty tone. All in all, a very classy system.
This system cannot be purchased anymore because Schnitzer no longer sells it. Back in the late 90s, it sold for around $1,200 brand new. I paid $800 from Bavarian Autosport a few years back, but now I'm asking $600. Yes, it may seem high for a 318ti exhaust, but this is brand new and is considered the best system you can buy. Besides, a brand new Remus system for a 318ti is $675 and a brand new Supersprint is $800+, so I think my asking price is reasonable.
Located in the San Francisco Bay Area. Shipping is going to be VERY expensive because of the size (it's at least 80" long) so I prefer a local sale. I can deliver anywhere in the Bay Area or even to So Cal for a small fee.
