I'm on the hunt for a set of used mufflers to use as a core for Fisters. I've seen mufflers for AWD / RWD / manual and auto from various 996 years with various part numbers.

So I guess my question is - will any set of mufflers from an NA (non GT) 996 work for my 03 C4S 6 speed, or are there variations?

Thanks
Charlie

 

I think you can exclude the Turbo mufflers




shown in pic is muffler from a C2 (40th AE) and a GT3 muffler (modified by Fister)
the GT3 mufflers now reside on another 40th

GT3 P/N's 996.111.122.91 / 996.111.121.91

You'll have to run the P/N's of the available mufflers to see if they fit
Porsche has different P/N's for 99-00, C4 & C4's and Tip vs Auto, along with pricing

I sent you a pm
