I realize this an off the wall question. I picked up a set off 2009 slashdown stock mufflers. The left side is not as restricted as the right and weighs less. I like the look of stock style mufflers more than any after market. I can get another late model left side muffler. This is a 2007 EG. Would it be a bad thing to run two late model left hand mufflers?

 

My 07 EG right side muffler is more open than the left side. I would like to have two right side mufflers on mine.

I put a set of stock mufflers that were non cat on my 06 EGC. and punched the two plugs out on each muffler. the look is stock like I wanted, and with the plugs removed I get the bark when I'm hot rodding. and the noise at highway speeds is not so loud. still have fast climbing rpm's and good power. also the two non cat mufflers weigh the same, and have equal exhaust flow restriction. they have little restriction after the plugs are removed.
