Guys and girls, have a WRX MY05 witht he standard exhaust - twin pipe. Would like to get a bit more of a growl, but not so much that my neighbours foundations shake when i turn the car over.
i know i need to change the exhaust, is it enough just to change the back box ( last segment) ?
then you have your diameter of cut, i guess nothing less than 3½". but what is sports cat, cat back, etc.

any brand names to tout, so i can look them up here in finland.

cheers
