Kline 718 GT4/Spyder exhaust
#211
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?

That would be ideal; however, you can derive some educated guesses from past knowledge about header design and HP/TQ data from equal length long tube design compared to shorty and mid-length header design. Irregardless, it would be interesting to know why Kline did it this way. I sent them an email regarding this question. We'll see what they have to say.

We have the dragy thread to sort out the power data...

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.

I'll try and record some before and after sound clips, might bring in a buddy to make some recordings on top of my phone clips to try and capture the difference as accurate as possible. Hoping to drive most of this season and then decide if I want to get the headers, we'll see how it sounds without the headers soon!

K-Nut,
That sounds real nice. Not too loud with Valves opened and pretty much stock sounding with valves closed.

I have valve control , always open or always closed. Driving with open valves all the time (unless wife in the car ) and no drone , may be a little on there low rpm 1800-2200 , like I say may be . Sounds very good

Sounds great. Does the system come with the valve controller?
