328i E90 muffler delete mpg

grebski · 09-15-2014, 04:31 PM

I didn't the muffler delete on my 2009 328i. Sounds great but I think I lost some mpg.

Anyone else experience this? I want sound but no mpg loss. Option is to weld in a Magnaflow 11148 single in dual out muffler and maybe do a result delete. Anyone have any input?

You're just driving faster. I guarantee that's it
