Pretty Nice Sound

http://www.youtube.com/watch?v=cncSwnsdnXQ

This sounds pretty nice, maybe put on some high flow cats, since he complained that he's losing power because he doesn't have enough back pressure. But, I like it. Your opinions?

Loss of power due to lack of backpressure? Poppycock.

The backpressure required is very little. You MIGHT have a problem with not enough backpressure IF you run 3 1/2" straight pipes with no cats & mufflers out the back on your unmodified 4.6L engine.

Technically, it's not the "backpressure" you need, it's the exhaust velocity that is helping to evacuate or "scavage" the cylinders.

If your talking about the Grand Marquis, I love the sound. The 5.0 LX, its eh... i dont like the noise when its like rumblish , but i bet is sounds good pickin up speed. I like the Marquis cause it doesnt sound to aggressive till you get on the gas.
