The B3 is basically a PROPERLY Tuned 335i, so I am sure a good 335i high performance exhaust will fit your needs.hello everyone, i feel extremely civilized with my silent stock exhaust on my alpina. any ideas to what after market exhaust i can get that will sound better and yet give more power to the car as well?
The current 335i is a mono-turbo the B3 is a twin-turbo/bi-turbo.why didnt you bought a 335 and got involved with a lot of aftermarkets stuff,, these 335 are unbeliveble fast with some modification
SPEED COSTS MONEY...HOW FAST DO YOU WANT GO?? you need to get a decent stainless steel performance exhaust custom made to your requirements...dont know if anybody can do that for you in lebanon... ps i have a friend in belgium who has a shipping company with their own vessel which does trips from belgium to lebanon so you could get it shipped to belgium and drive to uk and get your exhaust done here as theres plenty of people who can do a custom job for your car.....hello everyone. i ordered and recieved from vividracing.com the AFE cold air intake dual air filter with scoops, active autowerke down pipes, and eisenmann race exhaust for my alpina b3 biturbo. what should i expect after intalling these items? now the alpina turbo boost is set at 16 psi. stock 335 is about 8.3 psi. ive seen 335 hit 390 hp when turbo boost is about 12 psi. 16 psi on the alpina and just 360hp then there must be something holding the power back. any enlightment is much appreciated. thank you
