Herrmann klappenauspuff 997 gen 1

[segermans]

Hi elfertreff people!

Right now i am looking to upgrade my exhaust system since the original porsche exhaust system on my 997 is too tame. I came across a company called Herrmann (sportwagen-herrmann) in Obersulm which modifies the original PSE (at least, i thought they modified the original PSE mufflers), which results in a louder PSE which is still valved.

Now my question is: does any of you guys have the herrmann klappenauspuff installed on their 997 and what is your opinion on these mufflers?

Thank you!

P.s. excuse me for typing in english, my german is bad

Kind regards

Hans
