Re: cutting down two bros exhaust on 954??
i really cant say for sure but how does the lenght of the can effect anything more than sound?
i ask this because i really dont understand, the restiction factor has already been addressed when you replaced the stock can with the bolt-on which is more open which also increased your sound so how does shortening it reduce more restriction? is it because it now has less lenght to travel through? and if that is the case, would it not benifit more from no muffler at all?
