Muffler question

[Roger3]

The thing is I took the catalyc, and resonator of my car and put just a pipe. Now I wan't to put a muffler but I just don't want it to make like a rrcrrrrk sound when i'm shifting gears like all the other cars in my town ( I hate it so much). I'm trying to find a deep sound. Thanks

I have heard the supertrap -- it sounds really good. Its has a low tone and its not real raspy when you get on it.
