How much louder is it with headers? I've been debating on getting headers for over a year now LOL.
is it louder on lower rpm? Any other differences?
Post #744 above. Go to my instagram and there are no headers vdos about 6 months ago. The should is about the same but much more volume lower and a bit more upper. I was on the fence too and its been well worth it. Drone almost completely gone as the whole systems works best together.
Maybe some of the guys this weekend who actually heard my car can chime in and respond about how it sounded!? The overall feedback was very favorable... I am happy I put in the headers (and Im an older guy... 60... who daily drives my GT4 everywhere)!

I'm a big fan of the headers as well. Deepens and increases the tone under 4000rpm (more pleasant by my ears as well) compared to exhaust/OAP alone, no drone, and increased performance. Above 5000 it is less musical but angrier and louder for sure. I think all of us who have added Kline headers after having just the Kline rear section/OAP and shared impressions before and after have left them on and prefer them versus not having the headers.
Congrats! Was out with the LA Pclub yesterday and many complimented the sound of the Kline full system for the GT4 - and ill assume they know what they like. Its a big step to throw on expensive parts to a GT car, but agree its well worth it in this case. Enjoy! PS... How about posting up some sound bites (can never get enough I think)!
Was supposed to meet up with the PCLUB guys, but I had an appointment to do some touch ups on my PPF. NEXT TIME! I want to hear the difference between the header/nonheader version.

Just PM me and we can meet anytime... its a fairly substantial difference, in a good way (not just louder...)

I would agree with this. The headers does add more musicality to the sound <5k and just downright tintillating from 5k onward that keeps building to 8k. Has a nice wail, almost F1 like. No regrets here; especially with valves open.
Put my Spyder up on the lift for the first time since having my Kline system installed....Holy moly!! There is alot of space under there now -- looks like there are panels missing, but I believe that monstrous stock exhaust filled all that space!
I received an allocation for a 718 Spyder last Friday and I'm considering the Kline Innovation Valvetronic OAP's and Back Box with the Cargraphics Exhaust Valve Controller. Can somebody please explain the advantages of a Kline Inconel 625 system over the standard Kline stainless steel system? I'm not planning on tracking the car. It looks like it's about $3K more for the Kline Inconel 625 system. Is it worth it? I'm all ears.

Hello Jim!
Congrats on the allocation!
Inconel is our most popular seller. 50% lighter than stainless and due to the walls of the exhaust being a lot thinner it creates a higher pitched more F1 type sound.
Both Kline Inconel and Cargraphic Valve Controllers are In stock now and can ship today! Kline Stainless in stock next week.

Thank you.
The only advantages of inconel over stainless, as far as I understand, are (1) weight savings - stainless weighs almost twice as much as inconel, but still less than stock, and (2) sound pitch - inconel is higher pitched than stainless. I did not think the difference was worth the cost, but many others did. Both systems sound spectacular, IMHO.

Thanks very much Eric. Are there any differences in durability/longevity between the two Kline systems?

The weight savings in your wallet is most significant.
I went with the SS. The Inconel version does not save enough weight for it to matter anyways. It's also sprung mass, not unsprung mass so you will probably never notice the difference in weight. Besides the sound(maybe as I haven't heard the inconel version) is the only reason I would go for the inconel over SS.

I have not heard either in person, just clips online. However, I tend to favor the SS as it sounds a bit growlier to me where as the inconel is higher pitched. Some may prefer that but to my ears the SS sounded better. It I really wanted to lose weight, a lightweight battery and a Peloton membership are a better return.
