Anyone running a duel exhaust set up on there H3T? After searching around I can only find a single side set up for my 2010 T is this because the spare tire may have to be taken out for a duel muffler set up to fit like it does on the regular H3. Any info is appreciated.

 

So this doesn’t answer your question, but here is a related thread that may help you a bit.

Unfortunately, If you want a dual exhaust, I think your answer will be: “A custom shop.”
