RE: OFFICIAL Redcat Racing TRUCK thread
naviuk...it almost looks like your exhaust gasket has blown that is what happened to mine. read the page before or earlyer on this page for the rtv sealent I used for a new gasket. Or it could be the exhaust deflecter blowing it back at the truck instead of away from it.
nitrosteve22...to tell you the truth I don't really remember what the stock pipe sounded like, but I do know the new one help out with power on the mid to top end and has a rowdy exhaust note.
