Too many variables, you're right. Then we get put in the uncomfortable position of telling someone that their exhaust choice was the reason.

Depending on the system, it can be the x-pipe, muffler or possibly both. Don't really dig in further than that, as most are not willing to wait another 2+ weeks after their new supercharger was just bolted on. We'll go the power-focused and proven x-pipe route mentioned earlier.
