Hey i think you all know that i got a Toyota Corolla 1600cc. I am thinking of changing my exhaust backbox. I want to know if I have my exhaust backbox too big, would it lose power?
I ask for the powerflow backbox they said it would cost me £210 which i think its quite good. But i don't know what style should i have between the single cannon style or the twin exhaust. And do u have to tell ur insurance if u change the backbox?2#sosodav
