Replace the heavy and restricted factory MP4-12C exhaust with our lightweight, high flowing Supersport X-Pipe. We have an in-house Project McLaren MP4-12C that we use as a continued development platform for new products. This gives us the luxury of extended time to engineer the finest solutions available to extract power and glorious sound. It has our LT-Style tips in spirit of the 675LT. Completely made in house, we cut, brush, and weld each tip by hand and our surrounds are straight from our Flow Waterjet.
