Exhaust problem

Well I would say even if you had bad seals or whatever, the exhaust still shouldn't be that bad unless you didn't have tailpipes. They work wonders and sound/ look better too. If you have tailpipes it's definitely leaking somewhere. Can't be that hard to spot especially with it being cold out. I think AJ said something about that in an earlier post. It's possible that your manifold could be warped or maybe the gasket has finally given up.
