I had the M330 and GPF back exhaust fitted by Fred and I'm very pleased with the results! The exhaust fits perfectly and adds a gruff tone to the engine inside and outside of the car, but without any drone in the cabin at all. The carbon tips suit the car perfectly imo and the whole thing looks factory standard. Excellent experience all round!
The exhaust arrived quickly and well packaged in a sturdy box. Fitting was very straightforward, everything lined up perfectly as the build quality is top notch. I opted for the matt carbon fibre tips which match the wheels and the dark grey trim of the rear valance. It sounds fantastic, deeper and slightly louder but with no drone at motorway cruising speed. Combined with the m330 map in Sport Mode the pops and bangs are epic. All in all an excellent bit of kit that I highly recommend.
Very pleased with the sound! sounds much better and deeper on idle and comfortable on motorway! pops are much louder which is great!
