Does such a product exist for a 2.7L '00 PreRunner?

If not does anyone know a range to expect for a custom exhaust?

you dont need dual exhaust not even with the s/c v6

need, HAH. this isnt about need, it's all about WANT! lol

I have dual exhaust on mine with a flowmaster. I have a 3.4 L in my truck. I love it. People can hear me coming down the street. I have more hp. When you reach about 4000 rpm with stock exhaust, the engine will shake. With the new exhaust it won't shake. The only bad part about it is that you cant go anywhere inconspicuously anymore.
