So I have a GR86 with AWE touring exhaust for 2 years. Love that sound in the boxer engine. Now the kids are getting older, I have to sell the car and can only keep the CX-9. The design on the muffler is quite similar between GR86 and CX-9 so I went to a muffler shop and have them welded the AWE muffler from the GR86 on to the CX-9. I kept the stock resonator and cat from the CX-9 because I don't want it loud.
It turned out surprisingly nice rumble sound without being obnoxious. All I have to say the same muffler on different cars do make a huge difference!
