Have you done the flapper mod?.. How loud is it when you drive on highway?... I really dont like loud exhaust sounds from so called performance mufflers... 'universal mufflers'... just too noisy to me.
And also, can you bend it back to its original place if you dont like the sound?.. would it break the part? |
The flapper mod isn't any louder on the highway, what it does is open up the sound on the lower end (ie below 45mph/3000 rpm)
the flapper is actuated by a Vacuum hose, at the aforementioned 45 mph/3000 rpm a vacuum causes the flap to open letting you hear the full sound of the exhaust. its as simple as disconnecting that hose and plugging the hole, pinching the hose or you can go to the extent of a three way switch ( off/normal/on , which several Vortexers have done)
I've used a one way fish tank valve which seems to work fine..
reversing the direction causes a flapper that is closed all the time= reduceds noise.
