I installed a Flowmaster 50 SUV muffler on my '07 4Runner (cut gas mileage 1mpg!).
The LOUD sound resonating back in the cab was like a sick cow, moaning from both ends at once (YUCK!)!
Midas suggested that I try a turn down eshaust tip, but all they had was chrome plated- They said that the exhausst acid would eat it, and recommended stainless.
The problem was that that Toyota used a metric diameter pipe tip (about 2 5/8"...), that no bolt on would fit over!
Midas welded this tip on, and it matched perfectly!
-Another plus is that it flares out to 3", and does not restrict exhaust flow at the bend!
Bottom line!- It cut resonating by 70%, and I can live with the noise (now sounds like my neighbors John Deere diesel tractor).
Wish I had never installed the Flowmaster muffler!
