I just spent part of my Stimulus Check on a new exhaust for my Ebony. It's a Vortex, by Cherry Bomb. So far I couldn't be happier! I wanted something a tad quieter than the Flowmaster Super40, yet with better low-end torque and gas mileage. I am still testing the mileage part... but the torque is better than stock! That's all I care about right now. The muffler is similar in design to the Flowmaster, but with a surrounding of fiberglass that adds back the backpressure that I lost. The sound is also similar to the Flowmaster, yet without the "hollow" sound. $275 later... smiles all around!

Some of you are probably saying:

"I wouldn't be caught dead putting a "Cherry Bomb" on my vehicle..."
I thought the same thing when I was told about the Vortex. Turns out Cherry Bomb was bought out by another company that gave them a bit of a turnaround.

Here's their website for more info:
