JHM did the work on this unit in Feb 2014 and the car was driven for about 30,000 kms since then without issue.
Price wise the thing you have to keep in mind is that with JHM they want your old manifold back otherwise they keep the $500 core charge.
Also I added the tapered head port matched intake spacers ($100) and the heat shielding ($30).
I bought the manifold first so that if I ever de-mod I could sell it but it cost me more in the beginning.
It is powdercoated bright Red!
I'm willing to do $1550 Canadian which is a steal since this would cost you $1930US + shipping right now.
And if you ever sell your car then take it off and it will still be worth good money.
It's not a part that wears down or anything like that.
It was one of the best mods I did on the car. Definitely noticeable once you get the RPM up higher. The car just pulled harder afterwards.
I have the install DVD if you want to do it yourself but my shop only charged me $200 to put in on.
