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.
