You don't need a thermal reactor unless you are concerned about emissions. You can ditch the OEM exhaust manifold, the air pump, and all the other junk. Most REPU owners install a Racing Beat header, silencer, and muffler. Racing Beat doesn't sell a kit specifically for the REPU but you can contact them to make sure you get the right parts and then have a local shop fabricate all the connecting pipes. In short, you're probably looking at close to $1000 to get your truck running. Do not attempt to simply install run of the mill exhaust components. The rotary engine will eat through them very quickly.
