Flowmaster 12018409 Outlet Muffler Moderate Review

I installed this on my mp2 87. Sounds good. It's a little louder than the stock muffler, but still not loud enough to wake up the whole neighborhood. It's also no buzz at highway speeds.

This muffler sounds great on my Civic coupe. I asked the muffler shop to remove the dueling mufflers in the reading and replace the resonator with this muffler which fits perfectly in place of the resonator. Then the central exhaust came out of the muffler. Sounds good without that annoying high-pitched "coffee pot" lawn mower sound.
