I dont think oval would suit at all. Anniversary rear with the Jet tip is all round win, could be a pain getting a valance that isnt going for silly money though.
Twin with custom made jobbie, my milltek worst system I've used over12 yrs been running vw's. Never again use use them.
Off topic, but what didn't you like about your Milltek? I've a full non res system from them and I couldn't fault it.
