Anyone know of any companies offering or working on an axle back valved exhaust system that allows you to change between open mufflers or restrictive mufflers? I see some axleback options but nothing electronically valved.

I have the lap 3 primary downpipes so im catless but its not worth it unless you get your car tuned or have a lap3 pro tuner. I even tried putting on some 200 cell hfc and it still a headache.

Good to see the open muffler still makes a little power with the tune. That 8 hp is looking like it could be more than a down pipe and mid pipe combined.

We now have dyno and dragy data on multiple cars that show the mid and down pipes add almost no hp on a tuned car but do put up the big numbers as advertised on a stock boost car. Its good to see the muffler still adds 8 even when tuned. People have been gobbling up mid pipes and skipping the catback and the catback adds more HP than the mid and dp combined.
We should have figured this out sooner when the catless cars weren't putting up the 1/4 mile times they should.

What results are those? The dyno numbers that I saw with JB4 mode 2 were significantly lower than mine with only intakes, surely my SSR intakes are not producing that much more HP. I have an open mind but it seems a little illogical to think that somehow that the Stinger is the exception when it comes to performance gains through the removal of cats.

Drag/Accelleration - Kia Stinger 1/4 Mile Times
Bottom dyno is the 3 hp gain with down pipes that add 30-40 not tuned.
I have 2 before and after 0-60 in 3.89 second runs from on the same day before and after SSRs.
