I wont even get into the legality of it, but from a performance aspect for a 4 banger, its useless.
its illegal to have an aftermarker exhaust. did it stop 95% of the people on this board? pretty much any performance mod you do creates more pollution. the more power you make the more fuel you burn which in turn is the more exhaust gases released. so should eveyone stop modding their cars? from Honda making the Accord go from 200hp to 240hp it created more pollution
and its useless on an NA 4 banger. with a turbo its night and day with and without a cat
