Hey guys, I have an injen exhaust and I was wondering if it was possible to dynamat the car inorder to get rid of some of the drone around 3-4k. Also if that is a good way to reduce noise where's the best place to cover?
Also, if you are running headers, what are you using for a cat? Straight pipe or hi-flow cat? Also, how old is your Injen exhaust (because my SSA Exhaust seemed to mellow as it got older... either that or I got deafer).
To make the biggest change move your resonator towards the rear of your car and it will make a HUGE difference. I did that and no more drone, i did replace my borla resonator with a magnaflow straight through muffler though.
There is only one problem I can see with Dynamat.Well here it is you added the cat back for more power?I hope you did at least J/K.The more dynamat the more weight you are adding.The more weight the slower the car.You could end up with enough dynamat that it would be better to remove the dynamat and put the stock setup back on imo. :3_smile:
