Sound deadening
I recently fitted a STi JDM axleback. It sounds good, but it has an annoying resonance at 2.5k-3k rpm. Do you think that a trunk sound deadening may help?
Thanks! Last edited by gpvecchi; 09-17-2019 at 07:13 AM. |

deadening. there's another fucking e in the word!
No, sound insulation won't do much. Your resonance comes from the exhaust, not the trunk.

OP, I’m not sure that you’ll ever get rid of it if coming from the exhaust. |

The issue is the exhaust, you can weld in another resonator in the piping to help with the drone.

Welding another resonator isn't necessarily going to fix the problem since he'll have to tune it to the specific frequency. It'll take trial and error.
Header wrapping the exhaust will make a difference, but it may not eliminate the problem.

You don't put it on the exhaust you put it under the back seat and trunk area inside the car.
