RB Pre-silencer arrived....one question?
 

I just got my RB downpipe/pre-silencer. It looks SWEET! Cant' wait to put it on.

Just a question: That little six-ports arm that comes off the pre-silencer...how do you plug that? I am going to be changing over to airpump driven six ports before I switch the exhuasts, and wont' need that backpressure line.

What can I use to handle the heat of the exhuast?

Thanks

Silicon caulk? JB Weld? Spot welding? Or maybe even high-temp gasket sealant.

Cut it off and weld it shut. Muffler shop should charge you about 10 bucks to do that.
