bang for your buck,
Secondary CAT delete, Res/OPF delete. Job done.
I got these from china around £200. They look real good. Tig welded with filler wire used. Not you usual rubbish from the look of them. Worth a punt at 200 notes
Stock exhaust is more or less straight through when the valves are open
Mapped that should easy give you around 730-750bhp depending where you go.
