Speedwerx will be introducing a new single pipe for the 2010 M8 and Crossfire 800. This is a patented design that allows the stinger diameter to be changed for elevation or fuel demands. This pipe will be available in late November and we are taking orders now. Pricing is not set, but shoud be right at last years price for the regular single. I will post pricing as it becomes available. These will benefit the lower elevation guys more than the higher, but for those that travel a lot this will be a really great pipe. PM me if you have questions and I will post more as it becomes available.
