PostPosted: Thu Feb 24, 2011 12:07 am    Post subject: 911 PSE Exhaust Hack also known as 'Gundo Hack' Reply with quote

A "GUNDO HACK", is turning a stock 997 muffler into a PSE (Porsche Sport Exhaust).

This is accomplished by welding a 1.5"-2" pipe connecting the 2 pipes of the muffler. It creates a much deeper and louder sound than stock, similar or better than the PSE.

This can be done by any local garage or exhaust specialist for about £250-£400 (prices do vary!)

Just remove mufflers, take them to a muffler shop and show them these pictures, and say: "DO THIS!"

Here are some POST PSE HACK (Gundo hack) PICTURES:






BTW the "GUNDO HACK" is called that because it was popularized by a USA Porsche owner Gundo, after he posted pictures and explanations and decided to do the hack with a larger diameter pipe (2").

Prior it was just called PSE HACK.

Following my previous thread on the Milltek back boxes, I have now purchased a second set of back boxes, which are having the gundo hack exhaust modification carried out as we speak.

Pictures and sound clips to follow......

May I ask where the name "Gundo" originated from.

I presume a US site?

Could be worse, could be Gozer the Gozerian.

So the Gundo hack is exactly the same as the Oettle hack for a 996, but for a 997?

I'm off to start a thread for the 998/991 ABZ hack! Laughing

Ideally use a lift, else some decent axles stands.
