Unique Motorcars also will build a kit with undercar exhaust. The Weavers converted my FIA car from sidepipes to street-type exhaust about a year ago (I've always liked the look, and I wanted to protect my 2 year old daughter as well.). After a lot of research on mufflers (many thanks to the tech guys at Flowmaster), I used the Hushpower Series II Shorties (12 inch case). These are typically used as a resonator in conjunction with the longer (18 inch case) Hushpowers. However, they are perfect by themselves for a Cobra, due to their small size, heat insulating properties, and "just right" exhaust note.

Based on my horsepower levels (~325 at the flywheel - very conservative engine around these parts), I went with 2.25" pipes. The headers are silver ceramic coated to keep down heat in the engine compartment, but the pipes are flat black ceramic to help them "disappear" underneath the car. With the Hushpowers, I actually picked up a little ground clearance compared to the sidepipes that were on the car originally.

In short, I love my undercar exhaust! (And my daughter does too; she wants to ride in the Cobra everywhere now!)

Hope this helps!
