Exhaust really loud inside the car

[whitemike89pl]

Hi everyone, I'm new here

I bought Tsudo exhaust and I don't know why but when I'm driving on the highway its really loud inside the car.
When I start driving its fine, but after like 5-10 min of driving the noise changes a little bid and it gets really loud inside.

When I drove with my girl from CT to NYC and then back to CT, she couldn't work on the drive-thru next day because she had problem to hear what people were saying .

I like the way it sounds but when I drive on the highway, the noise is really annoying. It sounds more like a have a hole in the muffler or something.
My friend has eclipse with loud exhaust but you can't really hear it that much when you sit in the car.

Before I had only muffler and same problem.

My Catalytic converter also needs be replaced (makes weird noise like something is flying in there). Maybe getting new Cat or High-flow would help?

does you'r exhaust have any resonators on it? if not this may help a little bit.

No, I don't think I have resonators. Where can I get them? Are those from ebay good or not really?

Dude, you can get them at like pep boys or autozone pretty cheap. heck you can even go to a muffler shop they stock tons of them, and they can weld it on for you pretty cheap too. the thing to remember with resonators is the longer the better. shorter = louder, longer=quieter.

Is there going to be any difference in exhaust sound? Those resonators won't make my car sound like crap right?
