I'd have to say that mine is unique alright, never heard a zorst quite like mine, it has a nice rally rasp to it and some seriously decent popping on lift off, just enough to sound cool and sexy. My car ain't no Lancer or Mirage or Accent...!! But it's just right for me. In contrast, Melbzetec's is just audible in the cabin, has a little stronger lower down torque but suffers from high-end restriction. It has a dual muffler setup, keeping backflow a little higher and restriction a little higher at the top end, giving probably a more reliable lifetime. My exhaust on the other hand has slightly increased low down torque over standard, but not like the Herrod system, yet the mid range to top end power is much fatter now, to the extent that wheelspin can be induced once you hit the power band in 1st and 2nd in the wet and a wet road will see 3rd gear change-in wheelspin (trac control light flashes

) I have it all on video too for y'all to see and hear, will upload soon!! Mine gives much better top end power than the Herrod system at least on a feel basis, although the two in a straight line would be interesting. Mine definitely has to be driven properly whereas the Herrod system is the more relaxed daily driver exhaust, at a slightly higher premium. It'd be a hard decision but on price alone I'm not regretting mine, I was blown away at the low down torque of the Herrod system though.
