Just installed mine tonight. I did a valve open cold start and thought "holy crap, what have I done". It does sound great.

One thing I recommend is that you measure the 3 dots on both sides to make sure they are even on both sides. I would also recommend cutting at the first set of dots leaving the pipes on the stock muffler longer. Fit the new pipes loosely then cut any extra off.
