Great exhaust manifold
(Mesa, AZ) | April 7th, 2017
I received this manifold yesterday on time. I promptly opened my new goodie and inspected it thouroughly it seems to be made very well I noticed it was a lot heavier than the stocker. I then went through and matched up all included hardware and nothing was missing which was awesome. The install was a little tricky cause the instructions aren't very clear but after some deciphering I managed to get it installed with little effort. Wow did this wake the truck up i noticed a sizeable difference in throttle response and lower egts as well Close to 200 degrees cooler. I would definatly recommend this over some of the more expensive manifold options as of right now only time will tell with age if this holds up to the grueling az climate
