From GM?s picture, they are showing an old SMA picture.
The SMA dual exhaust was made by Billy Boat exhaust.
Jason who owns this site originally had the exhaust listed as an SMA exhaust, but now that they are gone he has reworded the description and the exhaust is now called a Billy Boat exhaust.
The picture on Jason?s site here sure looks like the same type to me anyway.

I bought one of these from Jason and it made a major difference in the power/performance of my H3.
Where the H3 gasped and ran out of power going up a steep incline on the interstate or another highway it cruises right along now. The difference is like night and day. I love the dual exhaust.
