I had a local muffler shop weld in some 2 inch stainless pipes in the Gundo prescribed manner a couple of weeks ago. I finally took the mufflers to my favorite independent shop to get them installed this week. They sound awesome! I have heard the stock PSE mufflers and these may produce a very slight increase in sound over the stock PSE's. However, they sound very, very similar. I could not be happier with this modification.

Many thanks to Gundo and all the forum members who have offered advice on this modification. This is by far the best "bang for the buck" I have done thus far on my Carrera S. The welder charged $80 bucks. I bought the used set of Carrera S mufflers with 4K miles on them off Ebay for $150 and my independent shop removed my stock cans and replaced them with the Gundo modded cans for $95. I have a total of $325 in this project and still have my original mufflers should I need them when I sell the car one day. What a bargain! Gundo for President!

 

I second that!

Can you post some pictures to see how is done!!

 

Sorry I all ready so how is done

 

Had your local muffler shop done this before? I'm thinking of doing the same thing but worrier about going to a shop that has never done this.

I just did the Gundo hack with 2" pipe and couldnt be happier...It sounds AWESOME

 

Jsimon77,

My shop had never done 997S mufflers specifically before, but the shop regularly fabricated pipes for hot rods, etc. It is somewhat of a gamble I guess. I took pictures in showing exactly what I wanted and told them I wanted their best welder/fabricator to do the job, Just make sure they know how to weld and make certain they use stainless pipe and stainless welding rods. Keep in mind these are under the rear fenders and you will never see them unless your car is on a rack. I did not expect perfection, but my job met my expectations. If you want them to look really nice and the welds nearly flawless, Darren Fister (http://fdmotorsports.net/fister-exhaust-997-one) does a really nice job although it costs more. Good luck with the mod!

 

He has my Vote for Pres!

 

You can't go wrong with Darin. He did my two cars (996 and 997) and I'm very happy.

Nice sound, but how about the sport mode, I know that changes the sound because opens some valves, my car has that function if I go sport it will be louder than now?

Sounds like you have a sport exhaust installed if when you push the sport button you car gets louder. If this is so you really don't need, nor do I think you can have the Gundo hack done, on your car. What I understand you can do with a sport exhaust is disable the sport valve to have the exhaust in sport mode full time.

Best,

Matt

 

I did mine ~5 years ago by pulling the exhaust and taking the pictures of the modified cans to a Midas shop! To this day its my favorite modification.
