      Just the sound I was looking for. Relatively quiet though the gears and cruising but sounds pretty throaty when stomped on. It difficult to make a 6 cylinder sound good but the bigger chambers help deepen the sound. It's on a 4.0 Frontier. Very pleased with the sound. Guess you'd have to call me a Flowmaster fan. Fourth muffler with them.

      Bottom Line recommended

      The muffler would not fit in the OEM spot. The inlet pipe needs to be readjusted for a stock fit. That's why only 4 stars.

      From Lawrenceville, GA

      I wanted to replace the stock muffler on my 4 cylinder Accord with something that gives me a little more sound without being obnoxious like so many aftermarket exhaust systems and mufflers are these days. This muffler was installed very easily at a local exhaust shop, and once a tip was added the shorter length of this muffler was not an issue. The sound is great, without being "raspy" or "tinny" at all--it's actually a deep, low exhaust tone.
