What would you guys go with to get the most sound, the absolute loudest? Keep in mind this is a v6 (i know i know, but its still sweet, plus i save on gas and insurance)

Flowmasters 80 series?

SLP Loudmouth?

Glasspacks?

What would you guys go with? For complete value, I'm not looking to spend over $200 for parts, still on a budget!!

Thanks a ton
