Decent cat-back

Nice exhaust but fit and finish wasn't great. The head pipe was bent so I had to un-bend it to get it to fit. Also the instructions weren't as great as they seem. Needs to be a little more clear on the orientation of the muffler. Also, NO STICKERS were included! Now that its on my truck it looks good, sounds good, and seems like it will last.

Sounds Awesome!

This exhaust sounds awesome on my 2.7L Tacoma. It is now one of the best sounding 4 cylinders I've ever heard. I also put on high flow cats and an intake. You get slightly more power at high rpm and on the highway. I haven't checked fuel economy. The exhaust comes in 3 pieces, so take it to a shop and get it welded. By the way, have an aftermarket rear sway bar by Hellwig, and it clears the exhaust just fine.
