greetings and salutations! I am interested in a magnaflow y-pipe and since I'll be going to my exhaust guy, I am wondering about replacing the stock cats with magnaflow cats while its in the shop. I am not a tech guy but a question: is there only one stock cat? I find only one I love my cat-back, but want all I can get

I have read all the exhaust threads and whether there are one or two stock cats,they seem to flow well.So when I go to the muffler shop, I will have him install a Mag y-pipe and a Mag muffler. I have had the Raven muffler on now for 8 years. I am keeping the truck for the forseeable future because my next car loan will be on a 1969 Roadrunner Does anyone run a 14 inch Mag muffler?

Quiet a few people on here run 14" Magnaflow on their trucks, what convinced me to buy one for my truck. All be it I've had zero time to install it along with other miscellaneous goodies. There is a good thread somewhere about installation tips to it, just can't multi-task on my phone for crap. Although I those are on 4th gen rams so I don't know if installation tips will apply.

Here's that thread http://hemitruckclub.infopop.c...0038252/m/6501044926

That all depends on your current exhaust, single in/dual out or single in/single out etc. What your current exhaust pipe sizes are matter too. Like I'm a 3" single in/2.25" dual out. But had to buy a 3" single in/2.5" dual out muffler since they don't offer 14" muffler with 2.25" outlet. Or something to that nature, like in that thread they had to swell some factory pipes to make it fit. I always check with an online retailer like Autoanything or Autopartswarehouse for fitment and part #'s of what I want. Then do your browsing for best price.

The typical Y pipe used on the 03 is

I use a Magnaflow muffler but it is the 30" model and I moved the muffler as far rearward as I could.
