Replaced at time of frame replacement. Toyota mechanic said they were easy to install and that they fit very well.

Pros: 1. Made in U.S.A, 2. Made in U.S.A., 3. Made with quality construction, welds, materials...etc., Cons: 1. Cats are not universal fit, but each came with threaded bung mounted in top of cat for O2 sensor, which my truck doesn't use (sensors after cat in pipe). Hole plug needed to be tightened before install, no instructions, no sealant, no torque spec...etc. If plug becomes loose with time, exhaust will need to be dropped to reach and retighten as it is 1-2" from floorboards.

The Gibson cat back exhaust was very easy to install. Removal of old was harder than install. About 1.5 hrs. Start to finish . Nice throaty sound but not obnoxious . Horsepower was noticeable in the 2-3k rpm range. Very little drone at highway speeds. I would recommend this system! Good product at a fair price.
