So ever since installing my full race catless downpipe every time I cold start my car there's this raspy exhaust leak type sound coming from right underneath the driver seat. I've changed the 3 bolt gasket twice now and the noise is still there. I know it can't be a leak because there's no evidence of it. Just that ugly noise. And when I floor it I can hear it right under me aswell. Any suggestions?
