I think a buddy of mine wants the old flows but I'm not 100% sure yet.
Want em' if he doesn't?? I head down to H-town often and could drop them off for a decent price.

They are "no" chambered. They are basically a flowmaster style casing with a straight through flow design with stainless steel packing around it. It's sorta a turbo, glass pack and a flow master jammed into one. It's raspy but they're gowing on me.

My cam is an Extreme Enery Comp 268. Not too terribly huge but this exhaust makes it sound like I've got 12:1 compression with a 284 cam in it

Also, I definitely noticed an improvement on throttle response and power/torque all across the RPM band.

Sounds awesome, need some burnout pics with these so we can really hear em sing, they sound much better than the flowmasters.

They sound pretty cool, nice throaty grumble at idle, I thought when you romped on it they sounded more like Borla's.
