I plan on getting TSP true duals soon and will be switching from a catted ypipe and slp catback exhaust. Do I need to retune the car or is the car going to run to rich or to lean?? I've got full bolt ons and heads and cam right now and the car has been tuned for my current exhaust.

Anybody have any issues with this switch?
