Good Product But.
Michael Korhummel (274 Wood Street, Unit 505) 10/9/2015 1:24 AM
My overall impressions of this product was wow. Its built much better than OEM and should given its 3.5 expensive as oem. Installation was tough but I did not take off the turbo. Everything is given to you and I even got gaskets with it which is odd because they said that the kit did not come with gaskets. The manifold is not painted black as shown in the photo but has the stainless steel finish. On another not, they shipped it in a reasonable time given it was out of stock but the packaging was sub-par. The package was broken upon arrival and the exhaust manifold was exposed. Not a good sign.
