I like the exhaust by it self. it was quiet. after i put the HFC on the sound was a lot louder. I did a before and after dyno w/ the HFC after driving it for 3 months. I did feel a little bit of a difference.

 

I've heard so many clips on Youtube for exhausts and hfc's. So far I like the Invidia q300 paired with hfc's from Fast Intentions. Doesn't seem to sound to loud but has a bit of rasp to it. Did you notice any rasp from the hfc's?

 

Did you listen to my video?
