Lookig For Sound Deadening Tips
I am looking for tips on making the inside of the car a bit quieter. Basically I had not driven the car on any kind of road trip since I gutted the exhaust and installed a MagnaFlow muffler back in early September. Yesterday I drove the car to from my house to Cleveland about an hour long drive. Simply put at 70mph for an hour I came to realize that the car was very loud inside the exhaust sound becomes very deep around 2100rpm so much so it will cause any change in the cupholders to rattle, this wouldn't be an issue if that was not the EXACT engine speed at 70mph.
So now my question, I have never had to worry about sound deadening before so I don't know much about it. I have heard of Dynamat and I have looked into it and realized its kind of expensive. Does it really work that good? Does anyone have ideas of cheaper alternatives? The majority of the noise comes from the back of the car so I'm thinking there's not much insulation back there to begin with.
Just in case anyone wants to know the car is a 2007 6S Hatch
Thanks for any advice
