I have a small pin size exhaust leak at the clamp. I went to AdvanceAutoparts and bought an additional exhaust clap to hopefully seal the deal, but no luck. I might try to find some kind of "exhaust band", something about an inch wide might work. At this time I can't hear the leak but I was wondering if there is any other issues that I should be concerned about (performance, heat). Would that exhaust wrap stuff I read about work? Is this something I should just let be or should I resolve?
