w203 Stock Exhaust Piping Question.
What is the stock Exhaust piping size of our stock M271 C230 Exhausts? Muffler Inlet?
I searched with no luck.
Thank you moocho!

Interesting that it's 2.5". That's a lot bigger than I thought. If that's the case, it's no wonder that changing the piping on the 230K has not shown any significant power gains.

It is a rather big exhaust (comparing it to my Jeep) considering if the M271 does in fact put out 11 PSI max, than at redline the engine puts out about 345 CFM, where as my Jeep with a 318 V8 put 480 CFM through 2.25" piping!
An interesting note, the M271 at redline has the volume of a 3.15 Liter engine.

Either way, everything is starting to make more and more sense (i.e. why there is not much gain from upgrading the exhaust piping). When I put the custom cat-back exhaust on my mx-6 (2.5" piping and Sebring muffler), it showed between a 8-10hp gain (but the stock piping was something like 1.75).
With the stock 230 K piping at 2.5 already, I can see why people have said that upgrading the piping potentially could cause a loss in power (very slight). Although, if a company comes up with a way to generate more power on the M271 and more boost from the supercharger, increasing the piping size would probably have more benefit. We'll just have to see what some compaines come up with.
