leaking downpipe

tkong · 05-31-2015, 12:28 AM

Today, I went to install my pe exhaust with ramps. Install went fine; however, driving uphill, I get this incredibly loud drone and vibration resonating throughout the cabin. I have catless downpipes as well. I've had catless downpipes and pe exhaust on before and it definitely didn't drone like this going up hill. I'm thinking I accidently loosened something at the downpipe area when I was taking off/fitting the exhaust back on. Or maybe I didnt tightened the clamps enough? Any thoughts on trouble shooting?

Thank you
