Got this fitted together with the air filter and the difference in driving quality was immediate. Very pleased with the engineering of this piece. The sound is considerably deeper, especially on start-up. Sounds much better in- and outside the cabin on hard pulls. Engine roar seems louder, but without cabin drone. Pops and bangs are slightly more frequent. Definitely makes you want to put the foot down more often. Ultimately it still offers elegance in drive mode, so it's up to you which side of the beast you want today. Got the carbon tips for style points. Would recommend.
Item arrived fast and very well presented, exhaust very well protected by foam, Followed the downloadable fitting instructions. Very easy to follow and all parts pictured, anyone with basic engineering skills or knowledge.. car doesn’t sound massively different, but it does sound better, the pops and bangs sound totally different, in a good way, no drown on motorway, all in all a very good bit of kit. I imagine with the Downpipe, Sports GPF and the m365 map, it’s going to sound very good indeed !
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!
