Installed on a 2011 CM Tundra. Buyers beware, this is not suitable. The intakes are closer together than the stock muffler and the length is approximately 15-17 inches shorter than the stock muffler. Don't plan on doing it yourself unless you have welding skills. I ended up having to spend an extra $120 to have it welded at a muffler shop. This is after spending over $40 on additional pipes/fittings/clamps/hangers. Overall a good product, not worth the heartache I went through to install it. Buy from your local tire and muffler store, they will do it all for 140-180.
