Yes, I would put some sort of muffler on it. Lots of tracks and racing organizations require the use of a muffler. Don't go with an X-pipe on a drag car. To get the most out of your combo run a straight through muffler like a Bullet Muffler like i have on my car. To get the most hp out of a dragcar with exhaust..find out where the exhaust is the whitest and cut it off there. I have 5" dynomax bullets on mine and i actually picked up a few mph with the mufflers over open exhaust. Plus open exhaust gets annoying after awhile.
