After market exhausts - M3 Forum 2010 2009 BMW M3 2008 BMW M3 BMW E90 M3 E92

was reading some articles on the performance pickup by adding some of the higher end after market exhausts. like example this high performance one made by Meirnschaft (sp?) is claiming that on the prior M3 the HP was boosted by 10 to 15%. doesn't that sound like a lot just by changing an exhaust system?

what are folks here thinking - after market exhaust or stick with the factory version?
:rocks:

Exhaust are usually good for sound changing only

unless u install an intake and get software upgrade

Yup, on an NA car, changing the exhaust if for better sound and maybe a little better MPG...
