My friend has the two chambers which sound good but there is this guy with a nice blk fox with the ultra flos and they soung good two. Both cars have full length headers and an off road H pipe. But I would be driving down the road and hear some stangs go by and be like what the hell that sounded good and I cannot chase everyone and ask what they have. Any recommendations I want a good sound that bassy hollow sound that stangs have come to be known for!!!! [patriot]

I have dynomax with fms shorties and bbk or-h and I sure could go for more rumble. I would try the two chambers if I were you

I went from 2 chamber flows to Dynomax ultraflos and I can say this from my experience: I got a bit of performance gain from the ultraflo's like a bit more torque and the drone sound at 2000rpm is half of the flowmasters, but I miss that vicious flowmaster rumble.

Just a little interesting data:

Flowmaster 2-chambers flow ~400cfm each.
Dynomax ultra-flows flow over 1000cfm each.

Flows use a chambered design to 'pull' the exhaust gasses out of the motor by creating a vacuum in the mufflers that suck out the exhaust.

Ultra-flows are a straight-thru design. They flow as good as open pipe.

The Ultra-flows are stainless steel & come polished.

For supercharged & Turbo cars the flows are WAY too restrictive. There's been back-to-back dynos of a turbostang that gained 35RWHP from ditching the 2chambered flows for Ultra-flows.
