I got the first batch (3 sets) of sport muffler tubes finished and ready to ship. These pieces are mandrel bent and made from 0.060 wall one inch stainless tube. Due to lower than expected costs I have reduced the price to $100 (includes shipping CONUS). I have the first two sets sold, and strong interest in another two sets. This kit is designed for home conversion to the factory style Sport muffler. You will be required to do your own final fitting, cutting and welding. You will need at least two 1" bi-metal hole saws (Lenox are the best I found), a strong drill, a carbide die grinder, and a welder. I use a mig welder with standard .030 wire). Figure 3-5 hours labor. PM or call me if you are interested.
I can also convert your muffler for additional cost.
These tubes only fit the Boxster S muffler to 2004. I can also make the tubes for a standard Boxster muffler (they are slightly different).
