Glad to hear the delivery went as planned. Canada was a little tricky.

The 180 bend will always be an issue for ultimate performance. Any muffler that exits out the driver's side will have to deal with reversion pulses and back presure.

I designed that bend to take up the same physical space as the stock 930 unit but to have an exact path for the exhaust to follow instead of bouncing off of a domed wall. That is why I used a straight-through muffler instead of the typical large case that you see. The 180 bend is actually a weld-el that opens up the ID to a larger dimension than the path lead to it and away from it, which is 3" ID.
