Review on 🚰 T9351 Valve Diverter Valve: Unveiling its Unbeatable Advantages by Terrance Singletary

Revainrating 5 out of 5

Works well good for exhaust and emissions

I recently bought a used VW GTI Mk6 and am rebuilding the car and am changing or upgrading some parts on it. I'll be getting the tune soon so I wanted to update the toggle valve as a tune helper mod. They say that with a little extra power, the normal ones go out and start making a loud noise. I went for this piece and from what I can tell it looks well made. When I removed the factory part, I noticed that the one on the car was missing part of the shifter piston, so essentially it worked without it. Now I understand that there are people who like to drive their cars without them, but now I can really see the difference when I put a GFB in there. The car as a whole feels like the engine has a bit more torque and feels better between 1,000 and 2,000 rpm. I've read some reviewers who say they feel the car has more travel while using less throttle and that's what mine feels, the shifts also feel a bit smoother as the valving controls the pressure lasts, but don't expect it to do anything cool. Sounds. I drove mine on a country road late at night with the sunroof open to see if it made a noise similar to a vent valve but personally I can't hear anything. Maybe when I hit the ground and then let off the gas there's something like a very muffled pull, like maybe a Nerf toy gun is being used, but it's in the next room, so you kind of heard it, but you are not sure . I really can't hear it due to the sound of the engine and tires going down the road, which is fine, but I just wanted to clarify what for those wanting a potential BOV sound they think it's going to be becomes. I am happy. I've watched a few YouTube videos on spotting fakes and it seems true. Also, the inner valve on mine was brass, not black, so I thought it would be a nice little extra, I think it might hold up better than the plastic valve, but it all looks good.

Pros
