Ive got a 02 r/t and just wanted to know what kind of exhaust setup this thing has stock. How many cats are there? when i look under the hood towards the firewall it looks like there is one canister on each side of the manifold right before it goes under the truck, what are these? Im wanting to know if i should just put a magnaflow cat on it or go with the muffler and cat combo. I dont really want to loose any horsepower or torque with the setup so wich would flow better, the stock muffler or a magnaflow both with a 3" pipe all the way back? My 99 ram with a 5.2 sounded perfect with a magnaflow cat and muffler and 3" pipe and i want my r/t to sound the same because right now it sounds weak compared to my old ram, and my 5.2 picked up a ton of power from that combo and im hopeing to get the same or better results from the 5.9. any help would be awesome.
