Not exactly what your looking for but I have the OEM muffler only from my 2011. Has less than 500mi on it and is cut about 2in before and 2in after, live in SoCal will ship if you want to make an offer.
Thanks for the replies guys. My zip code is 31637. I can get a y pipe and muffler off of an 2011 from my local dealer for $125, the owner just installed a Nismo catback on his personal truck. Just trying to see if I could do a little better on the forums. PM me how much you want for the mufflers/y pipe. Thanks a lot.
I have a Frontier, so my Y pipe is the most restrictive I have ever seen. I was thinking the titan muffler might sound a little better as well, it's a lot smaller than the Frontier muffler. Hook me up bros
