A straight forward installation, the engine cover heat shield, o.e., doesn't exactly fit the same after the installation, even with the pin extension, the back pin won't engage the hole, but it stays in place. It really does add horse power and it's sound is awesome. I think the MPG has gone down abt. 2 mpg, on the highway I used to avg. 16.1 MPG, it's now 14.4 after a 260 mi. road trip, I'm still very pleased. We'll see.
