better than the dualies i reckon ... the dualies were more of a lets say... Doong donng Dooonng.. and where the ooracing pipe is more of a duhdudhduddhdhd.. its sound Very neat and also looks sweet while doing so..
i think the dualies HAD way too much flow personally... and i reckon it lost me a tad of power too...
but... deff worth 150 bucks Highly recommend!
