Hello my friends!
I have an N1 catback system and i love the sound!!
But the noise inside the car is extremely loud and I can’t stand out for more then 100km
So I came up with an idea to soundproof the cabin.
I have a few questions to you hope you can help me
Have any one of you guys done it ?
Is it worth to even try ?
What materials are the best ?
And where should I start to damp the sound ?
Thanks,
Filip
