It is made by TWM and is available through Top End Performance. They are located in California and their web address is www.racetep.com. The cost is $275.00 for fiberglass and a carbon fibre version is available for $525.00. This cost does not include the silicone hose and airfilter assembly. The quality is very good and it flows very well. If there is anything else I can help you with, let me know.
