Hey guys, i m driving a e36 325 tough of changing the exhaust system means the Piping,mid box, cateletic converter and ect ect.. Becos i realise there is 2 mid box 2 cat convert and the original muffler too ugly ... So wat i plan is that change the whole piping to 2 1/2 inch steel plus 1 center bullet and 1 tanabe g medalion... Wat do u think i need some feedback becos i m not sure is this work... For japanese engine sure work but wat about BMW ... Wat kind of exhaust system recommended... Definately i m looking to improve HP by changing this.. Louder the exhaust system is fine for me dun really need to silence...Hope to hear some valueble feedback from u guys....
