there has to be a down side here somewhere.otherwise we all would be tripping over all the tuned pipes . manufactureres would fit them to existing engines instead of making new larger engines. yes tuned pipes
can work but there has got to be a limiting factor here that we are overlooking .like I said if they are' all that" we should literally be tripping and stumbling over all the tuned pipes that came on the engines we bought and tore down .
yet,..... I dont have one.
