Agency Power Exhaust Install & Review

sinceday1 · 04-13-2010, 11:07 AM

It was an arbitrary scale to start with so I don't know... Making an adjustment to that scale would not necessarily give you an accurate representation. BUT if I must, i would say 5~6.
Don't get me wrong, it's still on the loud side. Def. louder than 18" FI exhaust or ARK exhaust (from what I've seen from videos, again, hard to make a comparator group out of those low quality youtube videos) I would rate ARK exhaust sound level somewhere around 3~4/10 loudness.

Exhaust comes with 12" resonator. and tad bit shorter but bigger diameter cannister(which probably contributes to the low frequency rumble) than on F.I exhaust. So if I may make a stipulation, it's probably somewhere near F.I 12" resonator exhaust.
Also, in-Cabin noise quieted down A LOT.
I have a video made on my camera but haven't had chance to upload it yet! I will try to upload it after my Con/prop exam this week.
