Downpipe do not increase boost pressure on their own, in fact they lower boost back pressure since you are removing the restriction caused by stock cats
That being said, it is always best to check with your dealership before committing to any mod (unless you plan on removing it before your visit) |
Hey Mike,
Just installed the m235i MPE on my n20 228i and looking for a little more sound, what DP would you go with?
Thanks,
Nick
