I,ve got a Mivv exhaust on my TNT, its nicely made and fits well, although its not much lighter than the standard can. As for power i've got some dyno time booked soon and i'll post up the results when i've got them.
Do we know if the Termi slip on has the mountings also? I really want the Termi, but after ringing PDQ asd a supplier in Italy, they both tell me that it could take till the end of september to arrive......not much good really, as i want it NOW!!:rolling:
