Right what do you lot think is the better exhaust for sound, build quality etc out of the mongoose, magnex, and scorpion, as i have a 4" magnex with flexi on my series 2 at the mo but have recently bought a mongoose and also been offered a scorpion, but have always wanted a mongoose on a series 2 have had plenty of scorpions and magnex's. But just wanted your lots opinions, cheers
