Valvetronic BMW G8x M3 / M4 Valved Sport Exhaust System*SYSTEMS CURRENTLY IN STOCK & READY TO SHIP!* Besides the quite strange grille setup, the G80 is a killer new M car, but like most, the sound is lacking. The Factory exhaust for the New G80 G82 BMW M3 4 does not deliver the goods. We fix that with our single 3. 5 inch mid pipe. This mid pipe incorporates an equal length design that allows for a very enjoyable high pitch sound experience without having to modify your OEM rear section. This mid pipe

Great in wall wire, easy to install
Size: 14/2 AWG-200 FT, Color: White
Ran this through studs for an in-wall 5.2 system, worked great, very easy to fish, wire threaded nicely, good copper, good connections. Easy to bend for 14 AWG.

Parts actually fit 11S.
Size: 23 Pack
Bought replacement parts from another vendor, but the brushes are nylon and do not last. Filters did not fit 11S, so I had to throw them away. Parts from this current kit fit perfect, brushes are rubber and seem more sturdy. Have not had to change them yet, but there were 10 replacement brushes in the kit, as the other kit only provided 4. Changed the filter also, picks up a lot more dust and dirt.
