There is no brand info on the page.. just called sport s muffler

Do they come with free earplugs?
Just looking at the picture, there can't be much baffling in there.....

From the description:
".....and features an open design for maximum air flow....."
so, probably no baffling at all. Just an empty drum, ready to drone.

Here's a look at what the oem exhaust looks like after dissecting it . I'd say there's enough extraneous baffling and insulation to quiet even an old dump truck .

Hell, there's even an old WW11 German Panzerfaust operators glove in there too!!
I hope it didn't have the owners hand still in it...

No. I have a custom aftermarket exhaust . This is just a file photo that I had.

I wonder what this sounds like!

Start a gas powered leaf blower, put it in a metal trash can and then stick you head in. You'll be pretty close!

Holy crap.
No wonder they're so heavy. I could insulate my fishing shack with all that!

Johnny D and others, Hi.
That library image of the opened up S exhaust, looks different to the image 'Crios' posted years ago. I can't see the separate chambers. I always doubted the flow direction he quoted and how drilling holes into the exit pipes before they leave the final chamber would achieve anything? Can anyone confirm. In theory we are lead to believe it does more or less the same thing as the PSE and allows gas to bypass the other two chambers. Really ?

EssexPorsche · 02-20-2013, 04:15 AM

This.....

Not sure how - if the gas came in from the left via the red arrow, how it could ever pass to blue? It would be more realistic if the red arrow was in the right and the gas flow from the right, then when the chamber was full, passed to the next chamber via the blue? My confusion is over how the holes that were suggested for drilling really change anything. To me its looks like the gas can only leave via the mustard arrow after being in the end chamber, and that the gas never really 'lives' in the middle chamber where the mod is proposed? Its not a big deal just interested. I have been viewing this sight everyday for about 6 months but never registered until today. I'm just a curious guy with a love for cars

One of the pics floating around is a 2001 S muffler that I cut open. It didn't look at all like that one. It had chambers and no insulation at all.

Here it is:

jacabean · 02-20-2013, 12:05 PM

I think the danger picture is of an 03 muffler

EssexPorsche · 02-20-2013, 11:54 PM

That's the one.

I agree that the inlet flow is via the red arrow, but that's about where it ends for me. If you numbered the chambers 1-5 (working left to right), surely the gas would end up in chamber '2' initially?

Then it would swell in this before either moving into the centre where it would collide and equalize with the gases from the other bank (pipe where green arrow starts) or be pushed through the unmarked tube at the front and out into chamber '5' (or chamber '1') for flows from the other bank.

Either way the gases end up back in either 1 or 5 and pass down a pipe you can't really see in the picture (mustard arrow) and out of the tail pipes in chamber '3'

As i see it chamber '3' is hardly used - so drilling holes through the inside wall of this pipes can't really improve flow or change the should in the way a PSE does?

Be interesting to know when the change in design occurred between the 2001 cutaway and Johnny D's 2003 example. But again drilling these pipes in the 2003 doesn't look like it would help? The pipes run pretty straight with only an equalizer pipe in between.

There was another hack out there that suggested drilling out the inlet pipe (inside chamber '1' and '5') reducing the amount of chambers the gas travels through. This would kind of work on the 2001 system but not the 2003.

Ha Ha

not really sure why I'm that concerned but I'm just one of those guys who wants to know why. I have i 2002 S - so its sitting somewhere in between the two models - no drilling for me - i really like the sound of a SCART system i heard on Youtube but that kinf of sound comes at a price. French company i believe.
