I had the Gundo Hack done today at a local well established muffler shop here in Denver (Bud's Muffler). They removed the muffler, performed the Gundo Hack and put the mufflers back in for $225. I love the sound! Not too loud, but louder, gnarlier and more winding begining at 3,000RPMs! Here are some photos!

 

Welcome to the club!

 

We be Gundos.

 

Cant beat it. Gundo powerrr

 

I really want to do this, but without knowing a reliable place to do it, I'm paranoid something will go wrong...

 

gunderiffic!

but sounds even better with headers, aftermarket intake/filter, and especially sport cats.

 

Gundo is the best sounding muffler out there, at any price. For the ultimate, mate that with AWE 200 cell sport cats.

Who came up with the gundo trick? Was it someone on the forum?

 

What type of tubing did the shop use? It's hard to tell from the photo.

 

Gundo, of course!

That's his username on Porsche forums, afaik

 

Does anyone have a video before and after Hack so I can hear the difference? The Fabspeed Muffler bypass seems a bit too aggressive.

They did a nice job on them. Appears they have done it before. Did you spec 2" pipes ?

 

Thanks! I really enjoy the throaty tone! It has a very exotic throatiness to it!

The weird thing is with the higher auditory feedback from the engine, I actually feel like the car is faster! I guess it makes sense because if the car was completely silent, there would be less sensory feedback to experience the performance. I now get tones at 3,000RPM, that I was not experiencing until close to 5,000RPM. A much better driving experience!

 

Thanks Cattman, I trust your opinion on this stuff. Where you running a Gundo Hack with the SC?
