Customer Reviews:

installed easy as total of 13 bolts undone, 1 O2 censer, 10bolts only to put back on, no drama what so ever, gave quite a nice note once you under it
from the rear, idle like normal, sounds mean when enclosed area(under bridge) and gives bit more HP wich i was looking for, every 4g15 engine needs
something, and this is that something i belive, put a smile on everyones face =)
