Performance Modding New 330i
Hi all,
I am a complete newb when it comes to this and am looking at getting a tune done and potentially an exhaust system.
The only thing that worries me is warranty, should anything go wrong. One suggestion that was made to me was to possible get the M performance exhaust system.. however I am unable to find much information on it for this car (from Australia) and it is also way more expensive than an after market one. The original plan was downpipe + bm3.
How many of you have done something similar and have you ever had issues in the past with mods and warranty?
Cheers
