If any one has a 3.4 with high flow cats and 40 flowmaster duals please post a sound clip!!!!
Anyways, right now i have one 40 flowmaster to a single outlet wich i will eventually change by adding a "y" pipe and another 40 flowmaster and tip, right now i want to find a good aftermarket cat with the u-bend replacement for my 3.4. i'd like to know where you got yours and what you think is the best.

 

from what i have seen dynomax is the best, but expensive at the same time.
magna flow also makes them. but i like the way the dynomax looks. that is on my list.

for the Ubend delete, i would say just take it to a shop. im sure they have or can get a "bung" for the O2 sensor and weld in a new pipe.


personally i would do a cutout so you can later adjust the sound. just like use the cutout for the Y. so later you can just either add an electric valve or just slide in a block off plate. that way if your going on a long road trip or a data your car doesnt sound like a bus.
