Hi,

Can you share me a picture of an original 993 Cup exhaust? I do not find information about this. and differences for RSR etc

Thanks for help.

Bill Verburg

There were 2 versions
40mm which is just the street header w/ the heater boxes stripped off
45mm
some used stock mufflers and cat(some cats were gutted) some have a transverse muffler. It depended on the series.
These are Cuo 40mm




this is a later RSR 45mm


Some shots in situ

Thanks very interesting. What do you think about the fabspeed supercup muffler with stock cat?

Supercups are nasty, fun, loud and can be very obnoxious at time, especially when you are trying to sneak out of the house or neighborhood . I had them and loved them for a while but ended up going with Fister 2 instead. In my opinion supercups are too loud, plus they drone... But everyone their own, you might love them..

Thanks I have just the RSR muffler and it sound no like an RS I look for cargraphic super sound? or add 100 cell cat to the RSR...

Adding 100-cell sport cats to RSR mufflers doesn't change the sound very much; it merely makes it a louder version of what it already is.

For track use, it's hard to beat Supercups with stock cats. Any possible 2700-rpm droning doesn't matter on track.

For street use, it's hard to beat Fister/LPMM/Ruf. Those are all pretty similar since they use a bypass pipe. (For the record, very few people use the Ruf mufflers. I only include it here because I believe they invented the configuration.)

I think going with the fabspeed Supercup with stock cats. If a member sell one ? Thanks

Bill Verburg

Before purchasing anything I'd check w/ the tracks to fully understand their noise restrictions, if any. For most of the tracks I go to the track car needs to be quieter than my street car. The penalties for exceeding noise can be severe including a request to go home.

If track dB isn’t a consideration...FIster Stage lll’s, AND Fabspeed X-pipe and 200 cell cats FTW

Metzeger

For those have the 993 supercup muffler with stock cats its not so much noisy in interior, experience welcome with this system. Thanks

Metzeger

Fabspeed supercup are clearly too loud by many users...I think going with cargraphic export muffler. Any members have tried ? thanks

I have a different opinion. I had RSRs first and then added Dansk 100 cell split cats. I think the sound became significantly louder as well as raspier when adding the cats. I think my exhaust is pretty spot on, removing weight and adding sound. I also think Eric had the same setup at some point.

Bill Verburg

My car has to pass Lime Rock sound, which is very restrictive, I use 993 turbo mufflers w/ cat bypass that keeps the sides separated, last trick was to use turn down tips(aka 'track fangs)

TheOtherEric

Indeed I ran the setup you describe for many many years. I agree it sounds raspy or wheezy. I tolerated it for so long because I didn’t realize how much better the Fister/LPMM is. 😀

Caveman

I have RSRs and cargraphic 100 cell sports cats and that combo sounds great.

Cheers,

David
