Anyone buy one or know someone that bought one, if so what are your impressions of them?
for the price they chrage u better off getting an aftermarket header.
port it your self it is not that hard. i ported mine
the collector is real restrictive and the lumps in the inlet part or the ports need to be almost removed and then a general clean up and port match.
I was rewarded with a smoother running and harder pulling eco
it is a bit louder but in a good way with a good growl. picked up some throttle response to boot. my wife even noticed that the car runs alot better, and in her words has some get up and go.
thanks for that info, I think I may go with this instead of a headder. Then come warranty time if I have a problem, they will never know my modification.
