Well I've been reading lots of post in these sections but none seem to answer my question just right. I've got an 06 Ram QC with the 5.7, superchips, AFE intake, ect. I'm going to get the pacesetter longtubes and would like to relocate the stock cats. My question is, can I get the "off road" y-pipe from pacesetter and still mount the stock cats? I thought I've read in a post of the stock units being "opened up," does this mean a shop can make the ends of the cats match up to the 3 inch tubing? Would someone be better off just having a shop fabricate the tubing for the converters or buying the y-pipe and having them modify that slightly? Any thoughts on which size tubing would be most beneficial for low end torque, 2.5" or 3"? Also one other area that someone can chime in on, I was thinking about keeping the stock muffler and putting on a turn down, I love a quite muffle that only rumbles when you step on it. Anyone been happy with this setup, or any other quite mufflers? Sorry for another exaust question, I just don't feel like I have a good understanding of the situation. Thanks for the help!

 

I would shop around until I found someone that is experienced in the mods you are making and then get his feedback on how to actually do it. What you are suggesting is all doable just needs a shop who is willing to do a little extra with making a custom install. The down side of running a stock muffler is wieght and of course most folks want it louder. Good luck

 

mine are opened up to 3" in/out. and I used the 3" off reoad Y pipe too so ask away with any question

 

there is no point in buying the pacesetter y-pipe if you're just gonna hack it up. if you're gonna put the cats in, just buy a magnaflow y-pipe and have the shop fab it up. it'll be MUCH cheaper

 

Uh no its not...

 

if you can get it installed for a 100 bucks or less wouldnt it?
