Exhaust? Duncan vs. Sparks!

[MK300racer7]

Im stuck between Duncan and sparks. which louder, last longer, looks better, worth it.

if i have to guess i would say sparks they are about 104 db i called them and asked. Some people have sparks and say they love it so i would go with a sparks:cool:

i have sparks on my bike...thing is sweet. i think it looks 100x's better then the huge rectangular duncan plus it sounds better. i think the duncan is louder, but the sparks has a good sounding grunt....so all and all i would recommend sparks no doubt.

umm.....i dont think duncan is louder than the sparks

And I think Duncan pipes are garanteed for life.....Does Sparks have the same deal?
