I am thinking about geting an exhaust system and right now I have the stock system minus the muffler, so its a straight pipe. I love the sound and I want to get the loudest system that will still give me some low end. Right now it has none. its a real dog at takeoff. I want a dual out the back system. And is there any system that exits on both sides of the back like the stock location, but on both sides. Any suggestions would be appreciated... thanks...

Flowmaster 40's are loud, but their dual out cat-back system does not use 40's. Dynomax makes a loud dual out cat-back. The highest flow, loudest system is the "Ultra flow" . It can be a welded or a stainless steel muffler. It is straight-thru design, and sounds like a Z-28 on steroids. Look at dynomax.com for descriptions, and at a-1performance.com for flow, sizes, numbers, and prices.
