They mention up to 20 hp but is that what? WHP or bench? de-catted, catted, full system, cat-back, 100 cell or 200 cell cats????
To be honest, IMO this is just a random number they decided to use...they took exactly same info from the 718 GT4 system specs...it still has the same typo error in the quote for the number

Again shows how much research they are doing on the power gains dept.....it does look beautiful and the Inconel option is nice...and some will like the sound coupled with WP tips.

So far Dundon has numbers that you can trust and probably next week another major player will have more data to show the RL community.
Preliminary results are pretty good but it all works as a system and needs to be correctly designed for the car.
What I'm seeing is a lot of manufacturers taking their 718 GT4 offerings and altering flanges and/or and bit the looks....that's assuming the GT4 system was already optimized.
No problem if you want looks and sound but paying $1000s with sub-optimal power increase results is a waste of $$$$$$ IMHO...of course, I'm a track rat and power is my top priority.

BTW...check in detail the graphs for both of those manufacturers. IMHO one is doing the marketing talk.

That's because their muffler design is like OEM....each cylinder bank with valves open dumps independently, no gas mixing or x pipe which is the design you want to get that Porsche sound.

It's pretty ridiculous that the Kline system was announced a week ago and although it's ready to order, there are no audio clips of it on their socials, just hype videos with stupid music.
