We will now be selling the SD, now ESR radiators and the SD exhaust. We have redesigned the SD exhaust on all the NB cars and it now fits correctly without rattling on anything. We will also be taking a look at the NB 1.8 and the 1.6. We have also changed the hangers to new bullet style so they can't easily slip out of the rubber hanger on the car. We were able to keep the SD exhaust within $10 of the Saferacer price and we were actually able to reduce the prices on the radiators by $50.00.
