New Muffler Help

[Dexromethorphan]

I just bought my 97 GMC z71 and im looking to put a new cat-back exhaust system on. Ive been into imports and still am but I bought the truck because my family is country and around here girls like them (note* im 16). Besides that I need help finding a full cat-back exhaust but have no clue where to find it. We plan on stripping the cataliytic converter untless we find a high flow. Any help you can provide would be appreciated.

If you want to drop your converters you will have to change your O2 sensors that will trick the computer.
