Anyone use a muffler silencers? do they work very well?? I have a 2.5inch exhaust into a muffler thats gutted, so its pretty much just a 2.5inch straight pipe, i want the option to quiet it down when we go on road trips and such so i was wondering if the muffler silencers they have on ebay actually work??

and if they do how does it make it sound?...

And what type should i get, they have solid ones, then ones with optional slits cut out of it
