The turbo being at the rear of the motor makes things tighter and a little harder to work on. Ford helped this situation by equipping the stock downpipe with a cool V-Band clamp on the turbine housing that makes things a lot easier to disassemble. A nice touch from the factory.
The Cobb downpipe on top is a lot larger in diameter than the stock part on the bottom. The Cobb part has a high flow cat welded in and has stainless headed hangers that use the stock exhaust mounts.
We transferred the stock O2 sensors to the Cobb downpipe. The Cobb downpipe is constructed from TIG welded 3″ 304 stainless tubing. 
You can see the 200 cell high flow cat from the inlet. The downpipe's V-Band flange is CNC machined from stainless steel.
The Cobb downpipe attaches to the turbo with the cool factory V-Band clamp. One easy bolt to install and remove. The fit of the Cobb parts is perfect. 
The Cobb exhaust is also constructed using 3″ TIG welded 304 stainless tubing. It has a resonator and a straight through free flow perforated core main muffler. The exhaust is very well made and is even polished at the visible rear section.
