ok it's a mini beast.... but hey, I am going to eat so many ricers once I take it out Today I've fitted the Dynomax Super Turbos mufflers. The result is excellent, I don't get that way too loud up your ears noise from the MAC flow... At idle: it's much much quieter (you can now talk... and not shout to get yourself heard), but you know you have some aftermarket mufflers. When you get your foot down, wow the sound is awesome. It's loud but not too loud, know what i mean I've made one mistake I'll fix it tomorrow: the left pipe is touching the gas tank. So it does hit it and produce an annoying knock that gets into your brain really fast Don't mind the "cloud" of dust, we just had our driveway done, so everything is dusty.
