Mine are MIJ and the sound difference is fantastic. You pick the endpipes you want and whether you want NASCAR (like Singh's previous car
) or just a deeper rumble. I got the entire system for 360 quid and they said they'd do the same deal for anyone from the forum (including two extra back silencers that other customers didn't ask for).
They need to remove your towing eye and cut the lower valance.
Since having mine fitted, it's sometimes embarassing the amount of people (not just chavs) who look to see what's making the V8 noise.
