Sorry for the delay. I had the 2 middle mufflers deleted on tuesday. While testing out the new exhaust i wrecked some spark plugs and had to bring it to the shop..haha oops.

So while at the shop they did new plugs and wires and threw it on the dyno to make sure everything was ok before giving it back to me today.

With that said the car made 15 more Horsepower from when they had it on the dyno last summer just from removing 2 of the mufflers!!. They are pretty restrictive.

The car is much louder...its actually very stupid loud and drone now is definitely noticable but i think its worth it and sounds killer.

Its tuff to tell from a cell phone video but here is the before and after.

enjoy.
