Just installed a Borla catback and love it but I’m getting a very heavy vibration mid vehicle when I accelerate after just starting it up. Generally goes away once I have been driving for 15 minutes or so. Sounds like a woodpecker is in my car. Shop said exhaust was very very close to frame with no wiggle room for adjustments. Found a few cases on the internet complaining of same thing. I’ve emailed Borla and I’m waiting to hear back from them. Thoughts ? Solutions ? 2015 BRZ.
