I am selling a pair of 997.2 Cup headers (they have built-in 100 cell cats). They are used, in very good condition. I bought them from a respected member here on rennlist 2 months ago with the intent to upgrade my exhaust system but my plans have changed so I didn't install them. Also selling a pair of custom made side muffler bypass pipes with O2 sensor fittings welded on. These pipes are made from smoother 4-inch centerline radius mandrel bent stainless steel from Woolf Aircraft Company. The O2 sensor fittings are necessary in order to install Cup headers on GT3/RS street cars. 997.2 Cup headers, used in very good condition, $1600 shipped CONUS (OEM replacement header/cats are outrageously priced so keeping a pair as back up might not be a bad idea). Side muffler bypass pipes, new, $750 shipped CONUS

How do these compare to the GMG headers? I am very interested in this setup. I already have the GMG center bypass, so I guess with this, the cats would be my only "exhaust".

Great value for a set of cup headers. They're the same design as the .2 items except for freer-flowing 100 cell kats (as opposed to 400 cell stock).

Thanks for your interest. I have no experience with the brand of headers you mentioned so I cannot comment.

That would essential be factory Supercup spec sound.

Thanks for sharing the specs.
