BORLA 140276 Cat-Back Performance Exhaust System for 2007-2010 BMW E90 Sedan/ E92 Coupe 335i/ 335xi 3.0L 6 Cyl. Automatic/Manual Transmission Rear Wheel Drive & All Wheel Drive 2 & 4 Door.

First off shipping with Prime is a plus. Installation from local shop was average as he said it needed a little adjusting but he was able to get it centered on first visit. Tips and fit looks really nice. Considering this is the S-Type exhaust it will sound louder than Borla Touring edition and stock so I wasn't caught by surprise. Like previous review driving in city about 25-40mph hitting between 1,000 and 2,000 RPM will generate the most sound but not drone. I was able to use cars Bluetooth and have a conversation without issues. Listening to music isn't an issue either. I will drive it for a month and post if anything changes.PS: This will fit E90/E92 335i/ 335xi Sedan/Coupe 2007-2010Update: It's been 3 months and the exhaust had enough time to settle. I don't think it's gotten louder or quieter maybe about the same after settling. Growing up I always loved American muscle exhaust system and now I want mine to be louder! I am happy for now but I could always upgrade my downpipes this giving me more sound.Update 8-5-14: I was able to make it louder by adding Cobb tune (tune recommends replacing your charge pipe) spinning its turbo faster in turn getting more exhaust sound. I get compliments all the time on its aggressive sound when pulling up to valet or meeting up with friends.

Too much money for so little.Didn’t even come with all the parts to install.

1- did nor fit my car properly. The muffler tip is offset from the opening. I went and paid two muffler shops to adjust and were not able to center.2- The mufflers generate a an annoying drone sound when driving on city streets (speeds less than 40 mph). I am not able to listen to my radio or carry a conversation in the car with the drone sound. I contacted Borla to inquire. They told me that they were aware of the issue in some cars. They offered and send me pipe inserts and told me that it should take care of the issue. I had a muffler shop install them and did not resolve the issue.
