Stock cat back with forced induction peeps in here.

My car is a 19 whipple car with long tubes no cats with stock active exhaust. Now that the car has longtubes and no cats whenever i go wide open throttle even if its just a quick 1 gear hit the active exhaust defaults to normal and is locked for about 2 mins and i can't change it. Anyone else experienced this?

If i had to guess, with the exhaust wide open like that, the mufflers are probably seeing alot more heat than they would see in a full system, this heat would probably create faults in the valves. I suspect your going to need to upgrade your exhaust to something that can handle the new set up better, corsa as their system that works with active exhaust
