Could be, or it could be just a light initial jab of the throttle.

Hope that's the case for the claims. I had Kline's Inconel Turbo Back system on my 7.2TTS, and the sound was fantastic. There were a few skepticisms with their piping diameters within the TT community for HP production compared to the likes of Europipes, as well as others.

Is it just me or does the Kline system sound a bit deeper and more guttural than the other system on this platform? I think I like it better. Not as much of a high pitch scream. Maybe it takes on more of that high pitch sound at high rpm?

That's the inconel sound. It's deep yet high pitch once under load. That's what drove me toward this system. Here's my feedback based off of other videos and why I didn't choose the others:
1) Soul - Sounds great, but too deep for me. Would be my next choice
2) Akra - Too deep again, makes it sound too vacuum like from what I've heard in all the videos I've seen. Not the Akra I'm used to
3) JCR - Sounds excellent but out of my price range
4) cargraphics - sounds ok

Ideally I want something that sounds like the .2 GT3 with the Akra system

I’d love to hear more sound clips from both the stainless stell and inconel systems. From the 2 on this thread I actually prefer the stainless steel higher pitched sound but we really don’t have a lot to go off of. I’m sure they both sound great in their own right.

I'd be surprised if the steel exhaust has a higher pitch above 5k. High pitch at high revs is what Inconel is known for. Really looking forward to more vids on Kline.

I just saw this posted on the Porsche Spyder Global Facebook group by the owner and I’ve shared this link in hopes he is also a Rennlist user. I’m looking forward to hearing the full drive video, I like the sound so far.

I believe it's the FBO in Inconel, IIRC

[QUOTE=ltfl09;17223882]Hey Boys! We have our first documented install of the full Kline Inconel system (headers included). Not my car, I contacted the instagram user and the shop (@olsenmotorsports) who did the work and they directed me to this video. They said they will be releasing a driving video soon on the Youtube. I can't wait to have this installed on my car except I don't have the headers as I'm not sure if it's legal NJ standards? Anyone know?
This is my car , Olsen did fabulous job installing it, and Kline got me this phenomenal inconel exhaust, sounds amazing, Olsen place short video on Youtube of driving it, we have lots of snow and full video coming shortly ,
Stay tune

I got Kline inconel installed on my Spyder 718 and it sounds amazing, no drone, love it , I did not post any videos yet (super cold and salty winter) will do shortly
