I say go with a long magnaflow, a long resonator and about 4 ft of pipe. thats basically what i did. its noticeable at startup but driving around its plenty quiet until you floor it. but even then its not any louder than the flow was.

Edit: I'll take some videos today for you and post them at your request.

 

Please do, I just have to quite this truck down.

 

Sorry, Forgot. I'll write a note. I get off at 1200 Central.

 

Don't laugh at my dirty dash. I've been busy.

The mic on my camera pics up bass unusually well. But its not even close to as loud as it sounds. A good example is to try to listen when i floor it, you see the tach move but can't hear a big gain in sound.
The magnaflow is cheaper than the borla, but you at least get an example.
