i saw that thread about the plugs... i guess they withstand the heat??
i'll look into that..although I have no idea where i'd get them.. unless i sourced them online...
although that stuff would probably look odd sticking down into my exhaust tips...you'd probably see them from the rear of the car....
some kind of threaded receptable welded into the hole that accepted a screw in plug might be the best way to shut htem up - but retain the ability to open them back up shoudl I choose to...
if all else fails, i'm just welding them closed... or gert a new muffler.
i'd snap up an NHP system, ,but honestly don't feel like blowing $1000ish on my ehxaust right n ow. i honestly don't mind the stock sound. maybe i'm getting old.... i kind of like it quiet when i cruise....
