hi all. i have a vectra c 1.8 sxi 2002 reg. im wanting to put a back box on for a bit louder noise. anyone got any links to a back box i can put on my car. my friend is good with a welder and i know i will have to cut a semi-circle in the rear splitter thing on the bottom of the bumper as i done want to fork out money for a different bumper with the exhaust hole in it lol.
is there any exhaust of a vectra sri or gsi i can use or am i better off buying a universal back box and doing a bit of welding instead? thanks
