Hello all i just purchased a new slip on and had a few questions:

1. Do you need a silicone sealant on slips ons?

2. If yes to 1, where do you apply the silicone sealant? Between the can and linkpipe only? or Between the header and linkpipe also?

3. How high temperature rating is needed for the Slip on? And what product do you recommend?

Thanks in advance.

Thank You guys for the recommendation. After pulling off my exhaust and apllying the Permatex Red, my exhaust sounds much much beter. There was some exhaust leak popping going on before and now its completely gone. I will have to say +googleplex to using silicone sealant on slip ons.

thanks
