Wax your right about the blueflame sounding like an evo, thats exactly what i thought when i had mine done, should pull better than a stock evo with stage 2 and exhaust
Im very happy with my blueflame, its made out of the same material as the milltek, doesnt look as restrictive (pipework flows much smoother), sounds better IMO of course
. and has a lifetime warranty like the milltek.
The only reason its cheaper is that its on offer, otherwise it would be similarly priced to the milltek.
