Apexi PS Revolution Catback trouble

[unreal-icarus]

Hi,

I use the Apexi PS Revolution Catback exhaust system but have some trouble with it. When i lift my foot from the gas pedal and the rpm drops significantly my exhaust starts to make a loud "bang" noise. Did someone experience the same? Maybe the active silencer inside does not open and close as smooth as is should. I know there came a tool with the catback to adjust the spring pressure of the silencer, but i don't have it. Any recommendations?

best,
ica

Hello ica,

From what you are saying, I would tighten the spring and see what you get, or if you can take the bit out that closes the exhaust.
