heya, on my 3.4, over time i've noticed that my top end has became proceedingley crappier, like before i could easily chirp 2nd when i would shift, and i notice my car is struggling at the higher RPM's Like 4300-5400. now, it was even worse than this, then i relaced my aging exhaust with a new SS catback, and it got a bit better, im thinkin that my Catalytic converter could be plugged? It's original one and has about 65000 miles on it, and like I've said, it's like the problem has slowly gotten worse over time, and my exhaust does kinda smell like crapola... maybe is it worth gutting the Cat? i hate having my baby run out of breath like that!
