I copied Gundo's crossover pipe hack - This is a sweet hack. It works great on a base 3.6 997! I am very impressed with the results. It takes minimal effort and costs me $140 total. The sound is very nice and rich. It’s not too loud and does not cause any droning in the cabin. At idle it is almost impossible to tell with the exception of a slight little burble… and as the RPM’s pick up so does the sound.

I’ve attached a link to a video clip. I purposefully took the video outside to avoid any resonance. Please excuse the house – we are in the middle of having it painted!

Thanks Gundo! A most excellent hack!

can this be done on a 997 s 3.8?

 

Sounds good Matt

 

The mufflers on the 3.8 and 3.6 are identical and this hack is equally effective.

It confirms to me there is no reason for PSE, as this sounds nearly identical, is lighter and costs less.

Of course, if you actually use the sound dampening feature of the PSE, then all bets are off.

Matt,

Where did you have this done in the MA area?? I am in Southern Ma near Rhode Island. Will you be at the Autocross next weekend?? Love to hear it in person.

 

I'm 25 miles west of Boston... Had it done at a local Meineke Muffler and then painted them with VHT header paint. Where is the Autocross? Maybe we can meet some place... I am really happy with the mod....

Matt

 

I wonder how these would sound on Fabspeed mufflers?

 

Sounds great.

 

Matt,

Google PORSCHE NER, then look at the events. Next (final) autocross is at Ft Devon, MA (off Hiway 2) at the old airbase. Directions are on the Porsche club. Event is NEXT weekend. OCT 6. (Saturday). Event cost is $35, but starts early and runs all day. Normally 4/5 runs through the day, but you have to work when the other half of the group is running. Great fun to watch as well.

I am very interested in hearing your exhaust, since I have been thinking about it ever since I saw the 996 mod on Rennteam.

I live a bit further West and South of Boston, South of Worcester on 146.

A good lesson for the kids... "the Gundo Hack" https://www.6speedonline.com/forums/...91#post1347791

He had a by pass pipe welded between the muffler inlet and outlet .

 

bchow, i have a set of these hacked mufflers sitting in my garage if you want to buy them, or i can trade you for stock + whatever the cost is to modify.
