I was just trawling the my330i website n came across a simple mod,
Easiest Sport exhaust mod ever!!
On 330's the stock exhuast system has a vacum operated valve which closes a gate on the inside pipe, this has the effect of a baffle which keeps the noise levels down at lower revs. This unit is situated under the rear bumber on top and to the right of the rear siliencer box, easy to get to.
If you disconnect the vacume pipe from the exhaust vacum control valve which operates the gate, it stays open at all times, just remember to plug the pipe with a golf tee or something. The result is the sound of a sports exhuast but with the money still in ya pocket. It sounds great, best freeby around.....
just wandering if anyone has tried this mod??
would this be hard to do??
many thanks
