The Best Exhaust Valves in the World | Why Fabspeed Only Uses Helical Valves 

We can attest that our valves are the best in the world. Great to work with Joe and his team.

I made a pneumatic exhaust valve using a turbocharger wastegate actuator and a mid 90's Ford Crown Victoria throttle body. It looked similar in appearance to the ones in this video. Of course, I don't used my valve at 90% duty cycle, so it hasn't given me trouble.

$1,091.90 just for a couple valves...That would make my exhaust for my Lincoln around $4,568.9 without their controller kit....Us car guy's already lack common sense, but one thing I know for SURE is....My wife would Fkn KILL me!....Then revive me just so she could hold it against me...Cause lord know I ain't made of Lamborghini money...And that my fellow humans is Lamborghini money....Spent on an old Lincoln. They better be the worlds best of the best of the best for $545.95...EACH....Plus $56.37 for shipping...I think I'll pass...That's for folks with moneys to throw around....I think in the reviews people should mention the pricing on products because it IS a huge factor in deciding what's appropriate for us.

It looks fantastic; finally, it will be a valve that will actually last like an OEM. Unfortunately, the price and the fact that it's just the valve are prohibitive. It needs a valve that attaches to a good-quality muffler that has a loopback. Example (not of quality but) valvetronic exhaust or varex. I would love to have something 4" that I could put on the car without worrying about failure

I have the 60mm on my SVR. Like many others mine leak and rattle. Wish I could deposit the video but if you press on the valve the rattle stops. yes they are the OEM 60mm Helical electic actuating ones

I have an rx7 naturally aspirated and I would like to add some of these vacuum actuated helical valves. My question is how do I tune them to open up at what ever rpm I want? lets say 5k rpm. Remember that my car is naturally aspirated so I would need the vacuum actuated ones.

Does helical make boost actuated ones that open with positive pressure?

Do you have instruction on where this gets welded in the exhaust system? Where should I take my car to get this work down in Tampa FL?

are these universal to quiet down race cars cause im over the db rating for my local track my car didnt come stock with those new fancy active exhaust that the exotics all now have

where can I order this valve?

Ngl i had better luck with the china electric ones

AES are the best

Have you tested every exhaust valve on the market to claim they are the best?

all your so called tier 1 automotive manufacturers, Volkswagen Auto Groep aka Audi, Lamborghini, Porsche, Bugatti, CUPRA etc all use electronic valves not these awful vacuum valves. And these vacuum valves don't even have auto closure lol
