THUNDER MONSTER BAFFLES FOR LARGE DIAMETER MUFFLERS, If you have installed aftermarket mufflers or you have "gutted" your stock mufflers, drilled them out, removed or modified the baffles, have a free flowing type baffle, or have an application in which you are not able to install the Thunder Monster baffles in the rear portion of the pipe, Big City Thunder has Thunder Monster baffles that install in the exit end of the head pipe where it joins the muffler. As with all our other products the Thunder Monster baffles will provide the proper amount of back pressure, flow the exhaust gases properly and act as a superior anti-reversion device. This particular application is called a head pipe installation and with our Original Thunder Monster baffles will provide a deeper, throatier, aggressive hot rod/hot bike sound as well as improved performance or for a more subtle hot rod rumble our QQ Series Thunder Monster baffles will do the trick.
Original Thunder Monster baffles $79.95 per pair + S&H*
QQ Series Thunder Monster baffles $129.95 per pair + S&H*
ALL Thunder Monster baffles are compatible with fuel injection!
