I'm cutting out the stock Y pipe from my exhaust pipes as recommended. I am bumping up to 3" pipe from the Y. I need to know what size should I get for the Y inlet from the stock down pipes? My guess is that it's the 2.5" inlet to 3" outlet. My local exhaust shop advised not doing this, but they don't drive a 2nd gen Ram.

I think the stock down pipes are 2"? Be best to measure them before ordering parts...

 

Hey everyone, new here 1st post tho I've read lots before and want to thank you for all your helpful posts you guys are great! Anyways, my question wtf is up with my truck 98' ram 1500 sport 5.9 4x4...does the surge/jerk thing at 40mph and up..engine light doesn't come on..just put a new cat in (was a joy doing so laying on my back), also new plugs/wires..have had issues with the #8 cylinder & plug..ashy..miss code in the past, but no light for some time now, did a scan today and no code showing up...P.S. 265,600 mi. It's supposed to drive me down the road not up a wall! Thanks!!

 

Check the stickied plenum thread at the top of this forum. That is probably the cause of your ills.

 

um, I don't see it, thank you tho...I do plan on pulling the tb off and checking for oil inside the intake manifold, I think that's a way to find out if the plenum is shot..just got the tb gasket so I'm ready to go..
