For Sale 458 Speciale Kline Inconel Exhaust - Full System

I'm selling my Inconel 625 exhaust by Kline Innovation:

1. Inconel 200 cell HJS cat pipes
2. Inconel Valved X-Pipe Muffler
3. Inconel Manifolds

Brand new, this set up is $18,616 + tax


Selling my system for $8,500 + shipping from Las Vegas, NV.


This set up was on my Speciale for 1100 miles. I never received CEL, so the 200 cell cats were doing their job.


More info if you're an exhaust nerd like me:


This Inconel exhaust is 40% lighter, stronger, more heat resistant, and sounds better than Stainless Steel. It's a tiny bit heavier than titanium, but significantly stronger.


If you look into my post history, you'll see that I carefully analyzed different Speciale exhaust notes in person to the point of being able to recognize different Speciale setups by tone only. I found the Kline to be the best combination of a high pitch note combined with a lower, baritone undertone that gives it a "layered" exhaust note that I found beautiful to listen to.

Valves can be controlled by OEM programming or with any aftermarket valve controller.


I found this video to be the most accurate sound clip:
