Bought these thinking they fit the 991 Cup generations - they are a bit shorter on the top length and thus work on the 997's.

These have sold.

Good price. I want to try these but I'm concerned about how loud they'll be. Also posting because if it helps there is a set of brackets for these on eBay. GLWS! JBO

i used to run these on my 997 RS.

It was sweet.
Perhaps too loud for street. But awesome.

redmonkey928

Yes, quiet is not what you will get with these! Thanks for the bumps.

No such thing as too loud for the street Last question in your thread. Is the rest of the factory Supercup exhaust muffler delete? Or does the factory diagram have headers running into cats into side mufflers into the SuperCup exhaust? I'm just trying to gauge if I have enough back pressure to run one of these on my car. Hoping this may help your buyer. And I am genuinely interested myself. Best Josh

i ran them on my 997 stock cats.

These are v difficult to find when you need em!!

Had them on my 997 and loved the sound. Losing 15 pounds from the rear was an added bonus.

Same here! My neighbors want to water board me. Thanks TCS and Spy an Crex. I am sensitive to posting in another's thread but I thought I could answer a few questions for your buyers. These are mount and go if you have side muffler delete and proper length headers and a good bumper exit / pipe aesthetic. I know I want them. Best Josh

Configs from Parts Manual:

Hey, thanks for the questions and diagrams ^^^

As previously mentioned, they run straight back from the headers - so headers/cats to supercup pipes, and right out the back, no muffler in the setup. Neighbors be gone if using on a street car! Also, a decent reduction in weight, the Cup's certainly enjoy that as well when running these.

Happy to help with anything else.

Good diagrams. You posted the delivery setup and the standard setup diagrams. You should post the Supercup diagram. I think it will really help buyers understand if it will work for them. JBO

FLA997

I would have if the manual showed it - for some reason, only the three diagrams posted are available, unfortunately. But as someone already pointed out the Supercup pipes simply attach to the header cats, then straight out the back unrestricted.

Understood. My apology. I have the pic from the Parts Catalogue but I don't know how to post it. But the way you describe it makes it clear. Good call. My bad. Buy these pipes and save 40 lbs of side mufflers and 15 lbs of rear muffler! And get Cup car sound. JBO
