Fat Boy Exhaust

Taking my bike through inspection in New Jersey for the first time. It has drag pipes on it now and is LOUD! Thinking of installing 4" baffles to quiet it down enough to get it to pass. My question is, can junk bolt in baffles cause too much back pressure and damage seals, gaskets or anything else you can think of? It is about a 30 mile round trip to the inspection station. Also, does anyone know why the stock exhaust had a crossover pipe between the front and rear pipe? Was that some kind of pressure equalizer or something? Thanks for any advise.

Junk baffles (the $3.50 a piece tin ones) will make the bike legal, and cause just enough backpressure that it'll probably run a tad better, and a tad richer. It sounds like garbage to me, (too tinny) but it'll get you a sticker. It's also not a bad idea to keep a set in your saddlebag/tool bag, in case you gotta throw them in, in the event of a roadside check, or a safety check. Jersey has some weird stuff, like PA.

Stock head pipes had a cross over to equalize exhaust pulses.
