Exhaust hiss from rear area.....
 

Anyone have input on best gasket material/kit to use that won't start hissing after 3 weeks of new exhaust system install??? Invidia Gemini

Was looking at some of the gasket sets on Z1......

I know it's the rear passenger hissing - but eventually stops. Bolts are just about as torqued as I can go and it is dead straight under there......

Stock SST gaskets seam really good to me. Make sure the surfaces it mates on are clean and flat. Use a razorblade to clean it if you put any sealant on it. The ones with any fiber in them will eventually blow out and the donut type are complete junk. The fiber with metal in the center are OK but will eventually burn out. I think the stock ones are the best.
