Sealed up my midpipe exhaust leak
I bought the Oem to 3” catback exhaust adapter even though I thought I had tightened up the nuts and bolts to seal the oem doughnut gasket to my 3” catback exhaust in my 2011 Legacy GT. To my surprise, after installing the flange and 2x thicker 3” gasket to the oem doughnut, I got a perfect seal. My catback lines up better and no more leaks. Exhaust flow and torque is noticeable and no more exhaust leak noises under the car during startup. I think that even if you think you dont have an exhaust leak with your oem downpipe to aftermarket exhaust, get this adapter and be 100% sure. Youll be happy you did.
