WELCOME!
I agree the stock exhaust has to go. One of the 1st mods in my opinion should be the exhaust. Check for sound clips.

Personally, I enjoy that clip of the cherry bomb exhaust. It has a unique growl/rumble to it and it doesn't sound like it will be overpoweringly loud. I have my mufflers cut off with an x-pipe in place of the H-pipe. I think my resonators were cut off too. Its nice and loud and aggressive enough for me. Good luck and let us know whatcha get!
