M135i PCW backbox mod - opinion needed

Post by Mad_Mac » Sat Jan 13, 2018 3:11 pm

I want to mod my exhaust to give it a bit more powerful sound. I don’t want it to be really loud but bit more grownup with more noticeable crackles. I spoke with guy from PCW today and he said that it would be probably about 30% louder and shouldn’t drone as it has a flap.
Could anyone with PCW mod on m135i tell me how it behaves? Do you have any drone? Is it louder only in sport or in all modes? Does it crackle more or just louder? I saw some videos after the mode but unless you have before and after video with same sound level settings you can’t really tell. There is more videos with m140i but they sound different to m135i. Thank you for your help. If/when I go ahead with the mode i will make a good video on it for future generations :wink:
