I am one of those guys that just cannot leave a vehicle alone... and since I will be buying a Metris, (hopefully soon) I am curious if anyone has opened up the exhaust at all to let the turbo breath better? Don't need sound, but any extra power is good! right? :grin:

It won't help, because the turbo is computer limited. You'd need an ECM change to "open it up", which a bigger exhaust would help with, I'd assume. The basic package makes up to 380 some-odd in production spec (CLA/GLA 45 AMG)

Yup, maybe a cutout pipe to make the turbo spool quicker. But not a lot of increase would be had.
