I live in a neighborhood with rather restrictive noise covenants. I want to do the Gundo hack on my 997.2 CS, but I may need to go back to stock if my neighbors get too bent out of shape. Consequently, I want to do the hack on a second set of mufflers and keep my original mufflers stock just in case I need to reverse the hack (go back to my stock mufflers.)

Eventually, I may be forced to invest in a stock PSE system so I can turn the PSE on and off. However, I would like to try the Gundo hack first as it is much more cost effective.

If any of you guys are upgrading your 997.2 CS exhaust with an aftermarket exhaust and you want to offset your out-of-pocket cost, I am interested in purchasing your stock mufflers.

Thanks,

Warren

 

Hi Warren:
I am planning to replace my '10 997.2 exhaust, (car has 10K miles) with the PSE exhaust I recently bought that is sitting in my garage. How big a hurry are you in? I would sell my stock exhaust for $450 sans tips plus shipping.
Thanks,
Michael

 

The Gundo Hack at idle is only slightly louder that stock. If you keep your foot out of it while driving in your community and you should have no problems.

 

I also have the Gundo and agree with the above.

 

Move and get straight pipes!!

Live in a gated community? HOA?

There is good and bad for that..this is a bad!

 

Michael,

Are your mufflers coming off of a 3.6 Carrera or a 3.8 Carrera S?

Thanks,

Warren

Are the WB mufflers the same as the NB mufflers on the 997.2 for both S models?

 

Have a set of 997.2 mufflers off my 2011 Carrera Cab. They have about 3500 miles on them. Selling them on eBay <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150979115883>

 

Yes - a 3.8 has the same mufflers whether it is a wide-body or a narrow-body. And 3.6 mufflers will not do.

 

I will be another supporter of "keep light on the gas as you leave your house" - I also have a sensitive neighbor and I assure you he would have complained by now if Gundo was too loud. You just have to resist the urge to give your car lots of gas when you pass the sensitive neighbor...

Gundo hack your cans and enjoy!

I am new to the Gundo Hack Mod...is the Gundo Hack different than buying the Fabspeed Xpipes or the Sharkwerks equivalent?

Is the Gundo Hack just a less expensive way of getting the same result?

Sorry for the stupid question...I'm very interested in getting more "grunt" from my engine sound on my 997.2.

 

The Gundo Hack adds a welded-in connection pipe between the inlet and outlet pipes on each side exhaust muffler. Diameter is up to the owner: I recommend 2" stainless. The Fabspeed X-Pipe (not recommended' you'll lose torque) or their (or AWE's) crossover pipes (recommended; + a few HP) replace the center muffler on 2009 and newer 997.2 models. The center muffler adds two restrictive bends to the exhaust path, the crossover pipes eliminate this and provide a smoother path.

The hack will run you an average of about $200 at a good muffler shop for R&R and the mod.

 

Thank you PTParks.

I do have a 2009 997.2 - I will check out the crossover pipe and not consider the X-Pipe now based on what you said.

Does the Fabspeed Crossover Pipe mod have anything to do with the Gundo Hack mod? Are they related, totally different? Help each other?

Would there be any reason to do the Gundo Hack AND add the Fabspeed Crossover Pipe?

Again, please excuse the stupid questions...I am WAY new to all this

 

I have both (see signature) and the sound is perfect, in my totally unbiased opinion, of course!! You can do either or both depending on what increase in sound you are looking for. HINT: Just adding the crossover pipes did not do much for the sound, which tell me that center muffler is not doing much muffling and is 13 lbs of needless rearend weight (thanks, Porsche). The hack made the biggest difference. My only complaint is that I waited so long to finally do it.
