I have searched for this exhaust but failed to find it. Has anyone heard of the Dual Super Truck Side Exit Stainless Steel Cat Back Exhaust System?
Thanks,

Here is the Gibson supertruck exhaust. Some websites indicate a stainless version is coming soon. Bassani makes some stainless setups now that might suit you.

I have had the Gibson Super Truck exhaust system on my '98 F150 4.6 for a little over a year now and I have been very happy with it. It sounds great. It has a nice rumble at idle, which is far from annoying, but when you open it up, it really roars. I also installed Gibson's stainless headers.
There was a very noticable increase in torque and power with these upgrades.
