As long as you aren't using the same bananas as engine oil. Just watched a YouTube video on it last week. And I've never used this product, I like a weld or clamp better in a muffler

Thanks, this deal is still active! And yes this stuff works great. If you ever need to replace part of your exhaust, the interface between new and old may never make a seal just by clamping, even when it looks tight.

Follow the instructions, wear gloves, run the engine to cure the paste.
