Im new to this forum so first of all I'd like to say hello to everyone! I've been reading through alot of the different pages on this forum looking for information or pictures on how a true dual system would be set up on my 98 ram 1500. Its got the 5.2l motor and my main question really is how are the cats set up? Are 2 of them used or none at all...? Anyone with some info or pictures on that, it would be awesome to hear about it! Thanks!

i have a 2000 dodge ram 1500 5.2L v8 also, i wanted to run true duals but the guy that installed mine basically told me unless i wanted to spend a pretty penny it aint worth it because alot of stuff has to be replaced.

Yeah I wanna put headers on my truck and want to go straight back from there eliminating the y-pipe. Im just not big on having my chech engine light on all the time if I have to ditch the cats.

i ditched the cat and dont have a check engine light,. if yours is a 4x4 you mid as well keep the y-pipe, since the transfercase is on the left side you cant run the left exhaust straight back, plus the gas tank is on the left side so youd have to go around that anyways

I've been researching this myself, and I'll share what I have found. I hear the 2nd gen rams have problems with duel exhaust because of the location of the gas tank. I've seen where someone had long headers and had duels out to each side behind the drivers door. I'm going to crawl under my truck when I get the lift kit on and see what can be done, if I pull the cat.

I'm debating gutting my cat or taking it out. If I want to bring it back to the U.S. I will have to have a cat hooked up. If I gut it, I think I can put on a Oxygen sensor spacer on the second sensor, which will remove the error. There is also a post on how to make your own somewhere here, using two spark plug non foulers, or you can find some on ebay for about 15 dollars. They also make oxygen sensor simulators, wich is a circuit board you install under your hood somewhere.

I'm curious if the cat is removed why can't we run two pipes parrallel to each other for most of the way past the gas tank. Again, I'm going to look when I get my truck back.

That ^^^^ is right on. It's a physical issue but it can be done by running both pipes side by side until you get some room at the back end past the fuel tank.

My 95 has true duals, 2", I used stainless band clamps at the point where the head pipes went into the cat converter, (converter came off) saved a ton of screwing around, wish I'd invented them, tho expensive, worth every penny for this application, and I ran the pipes down the right side of the tranny, etc . went thru a 2 in/2out magnaflow muffler, and out the back, as for these pipes, I welded the muffler and pipes all together out of the vehicle after tacking them in place with outershield, installed. I don't know if you could get away with installing them welded together if you haven't a body lift, the bodylift allowed extra room around the rear axle. also, I use d aluminized pipe, and it's been on there since 2004. I was fortunate, as I picked up bending dies at an auction about 20 years ago, and can bend pipe well, using my loader, without destroying the pipe. I started at the back, and worked forward, and used the better part of 30' of pipe. the hardest part for me was fitting everything to provide me where the pipes went over the hitch, and under the bumper. The muffler is installed, oval top and bottom, and welded, located just before the rear axle, this saved me joints, using just 3 sticks of pipe, as the pipe came in 10' sections. The magnaflow is quite tame, until the motor is working hard, I wish it had a little pipe crackle, but if I remember from my younger days, if you want crackle, all you need do is neck the pipe down in front of the muffler, then make it big again. It's been awhile, but it seems like thats what we did in the RB block days... Simply welded the sensor boss onto the pipe, Keep the right depth... It didn't seem to make any difference in the ECU, my sensor sticks down more than I would like tho, thought I'd pointed it up more, but to keep the tailpipes right, I think I had to twist that pipe down a little, but it doesn't catch on anything...

yeah you can run both pipes down the right side, but IMO its easier to just get a catless y-pipe (did this on my ram)
