Ease of Install: Very easy
Rear Bumper Type and Fitment: Fits the TRD kit very well. Better than some others.
It was pretty quiet but sounded deep and clean. The Evo's design is like the stock GTS exhaust in that it has a large muffler between the rear wheels and a small Greddy canister and tip at the rear bumper. I removed the Greddy resognator, muffler, what ever you what to call it, in between the rear wheels. I get lots of props, people say I have the best sounding exhaust on any celica, or any other four cylinders period, I would not have any other exhaust.
