Thanks for posting. It doesn't sound any different from stock when only the headers are changed. Based on my understanding, stock CAT is already high-flow. Though this setup does sound great, the way to gain the most power appears to be moving the cat to the OPF area..
Standard cats are ~600 cell in the UK. Removing the opf does really help, but we cannot do that in the UK.

Stock CATS are definitely not Hi-Flo @ 600 Cells. During my conversation with Flat-6 and JCR, the most restrictive parts of the exhaust system are the stock headers with its 600 Cell CATS. Remove this restriction and the next most restrictive parts are the OPFs. The Stock Muffler is actually quite free flowing; especially with the valves open.
Took about 17 weeks, but finally received my Kline inconel OAP + valvetronic exhaust this afternoon. Shipping was pretty quick, left Romania on Thursday and arrived today including long weekend in-between. Hoping to get these installed this weekend, as long as the weather holds up.
S/O to Eric @ SupremePower for the hook up, great to deal with, kept me in the loop and had it shipped direct to me from Romania instead of passing through their shop.

I wonder why Kline went with this type of header design? Very similar to their header design on my previous 997.2 TTS. To me, it just appears to not be equal length, as well as, having the collector very close to the primary pipes. Not certain if these will make the same HP/TQ as the truer equal length headers with CATS like Cargraphic, Dundon, JCR, BC Fabs, Fabspeed, SOUL, etc. Any one with knowledge care to share some insights to this?

Wow, that's beautiful . I keep going back and listening to K-Nut videos of his Kline; especially the one by Olsen Motorsports. Sounds very nice and exotic. Not raspy or drony at all. Just not sure if it makes comparable power as some of the other well known brands.
^^^ Its not all about power or else we would all be driving different cars methinks. Its the sound most are after....
I guess that's one way to look at it, but you can have both power and good sound and not just one or the other with this engine platform...so why not? It has been understood that the OPF and Muffler affect the sound most.
