997.1 Muffler removal for Gundo Hack
Hey everyone. I am new to rennlist and just bought my first Porsche. Like a lot of people on this forum, I would like to make my 997 sound more like it should and would like to do a Gundo Hack. I took my car into a muffler shop today and they told me I had to take the bumper off to extract the mufflers and they wouldn't take the bumper off. They said if I didn't want to take the bumper off, they could do it in place with a plasma cutter. Any help on how to remove the mufflers myself or other info would really be appreciated.

Find another shop and tell us which city you are in so others can recommend a shop that will replace the mufflers for you properly

Yes find another shop or a buddy willing to help. If you are in the states contact Darin Fister for the real deal. Gundo's are the poor man's lobster compared to a Fister can.

Order the new cans from Darrin. Get some ramps, back car up on said ramps, unbox shiny new fisters. Unbolt old mufflers without taking the bumper off, place old cans in Darrin's box, ship them back and get credit for core, drive your car and enjoy the sweet sound of your car as it was meant to be.
With some mechanical aptitude it may take you two hours or less. I can probably do it in 45 minutes

I have fister's on both my Porsches from Darrin. Well worth it, plus it looks professionally done, quality work. If you are somewhat mechanically inclined you can take them off yourself.....you can take them off without taking the bumper off, just remove the rear tires. However, it is a little easier if you take the bumper off, but not necessary. It's as easy as Little Green said.....enjoy

Everybody is eager to spend other people's money.
The Gundo hack is invisible unless the car is up on a lift--and even then, i's hard to spot. The welds can be terrible looking and no one will know.
I don't want to be that guy, but you should do a search. There are several threads on this forum about the Gundo hack, some of which go so far as to outline what size sockets you need.
Bumper removal is not necessary, but helps. There are also threads that outline how to do that as well. I haven't done it but people say it's easy.
When I did the hack, I removed my mufflers myself without removing the bumper. It was not difficult, although I have a lift so I did it standing up, which is much more pleasant. I did remove the rear wheels as some of the bolts and brackets are easier to get to from the wheel well.
You can definitely do it yourself if you have another car to drive while the shop is doing its thing.
Good luck!

Thank you all for your quick responses. I live in Idaho Falls Idaho. Not a lot of choices in muffler shops. Everyone recommended these guys but I don't think they have every worked on a 997. anyway, does anyone have a link to Gundo's video of how to remove the mufflers. I will attempt it myself.

Fister is a nice product and known quantity. Welding exahust pipes is not trivial if you weld for a living.

Don't have to remove the bumper, but doing so is simple and makes the muffler job easier. DIY here: https://rennlist.com/forums/997-foru...p-by-step.html
Suggest you soak with good penetrating oil--several days in advance--the nuts\bolts on the sleeve clamps joining the mufflers to the cats. They'll be rusty and wrecked, so have new ones on hand,
I did what I believe is the "Hanksville" version (997.1 Muffler Comparisons - Stock vs Fister vs Hanksville Gundo - YouTube), mimicking the factory PSE routing. Had it done in stainless by a local shop that builds motorcycle frames. The work looked so good that I then had to waste an entire day cleaning and polishing the mufflers to bring them up to par. No one will ever see them, but I know they're there...
Good luck
