Most any exhaust shop should be able to come up with something for you...
You'll have to cut out the left side of the bumper to match the right side.
Only problem I could see is that a majority of the piping is going to be on the right side and then you will have to just weld in some new piping or a Y and split it off to the drivers side. Which would only help with looks.
But will add unnecessary weight. Not to mention will look quite ricearific.
yeah there are a few cars on this forum that have dual exhaust. mayo and thundercloud are the first i can think of on top of my head, both have great setups, each muffler shop charges different. go to a few shops and get some quotes, and you gotta make sure you cut a opening on your passenger side bumper... i dont know exactly that process?
Honestly, I like it. But I do realize dual's tend to lean towards rice but I think it looks clean. Only problem is whenever I get my rear lip, I'm going to have to get another cutout for the exhaust but shouldn't be a big problem.
