I had ricks egr kit on my truck until i did my twins. His kit worked, fit, and looked awesome. Id buy it over again if i didnt have twins. My buddy took it from me and is on his truck currently and has no complaints either.
The best benefits are cleaner intake/oil the power and torque you get from Tony's kit is just the engine running right. Boost comes in like you love to see and feel it. Run down the interstate with cooler EGTs and a no smoke EFI tune putting out hi 400 hp area is a great investment.
