It's hard to believe I was able to buy a Flowmaster muffler for only $100 in 2013. I installed this on my 2008 Toyota 4Runner which comes with a 4.0 liter V6 engine. It's hard to choose a muffler for a V6 at the risk of sounding terrible. I also removed the rear resonator. The sound is certainly louder than normal, but not too bad. It is not uncomfortable and worth buying. I have used this muffler in combination with some other minor performance modifications. It just exceeded all expectations. If you need something quieter I would recommend the 60 series. I am happy with the result and will not change my mind.
