When you delete the cats,dont you need to do something with the lambdas?I have a friend of mine who deleted the cats on his SRT-10 and he had to connect a small electonic devise to switch off a fault light inside the car.How is it on the GT?
The muffler does not make any more power, just sound. And the headers are only worth a little. Something tells me you percieve the car is faster due to the sound.
How do you like the sound and did you do the muffler or headers or both?
