i was planing to put 2 HKS universal mufflers with custom true dual piping.. and the muffler shop told me that they canNOT do it because on the rear right there is a fuel pump? and i was like wtf .. fuel pump right there? but anywayz. there is a black box on the rear right hand side so the muffler wouldnt fit.
um... what the hell is that black box? can i remove it? tips??
