So I found this on JEGS and it says 94-99. I have an 01 4x4 with a 5.2. Will this Y pipe fit??? Thanks...Joe

 

IIRC, it will but might need slight modification. As to what, I dont know.

 

yes it fits perfectly. i have no idea why they don't say it fits 00-01.

the length of the pipe will exactly reach to and line up with the stock muffler on a regular cab short bed. for the longer wheel base models, you'll need a 2-1/2 inch extension pipe, available at any parts store.

JEGS Performance Products 31020 - JEGS Off-Road Y-Pipes for Trucks Details

All to 8500 GVW with single 2-1/2'' exhaust after the converter. 2" inlet to 2-1/2" outlet. Slip fit connection.

JEGS Y-Pipes provide maximum exhaust flow for off-road truck use. These fit directly from the manifold to the stock cat-back exhaust for all 2WD/4WD applications and wheel bases. Constructed from mandrel-bent 16-gauge aluminized tubing, the pipes include flanges, gaskets, oxygen sensor bungs and plugs, and exhaust clamps. A JEGS cat-back exhaust system is recommended to receive the full benefit of the increased exhaust flow. Catalytic converter(s), sold separately, can be added for street-legal use, yet some modifications will be required. Made In USA

 

Hummm interesting. After some more research I think it will fit. I will also be doing Flowtech shorties, and getting rid of the stock cat and getting a spun hi flow in which i will also do the non fouler trick. then from the hi flow will be a single chamber muffler with duels out the back.

 

Definitely need to do before and after exhaust video clips.

 

Don't forget to check your plenum plate (if you have not done so) before installing new o2's.

 

Pics and video please thanks and the more info the better

 

I suggest you read the plenum sticky.

 

stewie01--I'm a deff. keeping documentation of what I'm doing to the truck and are for sure doing pics and vids. Even I want to see and hear what the before and after will be. And zman17...I have read about the plenum and actualy already have the Hughes kits and I also got their tune up kit. I just haven't had time to put it in yet becuase it will be a friday saterday job. Nothing will be done to the truck performance wise until the kit is in. This fourm has been a huge help. Even though I know alot out Dodges, I had no clue what so ever about the plenum issue. You guys are life savers. Thanks again.

 

anyone have a pic of what that Y-pipe actually looks like?
how long is it after the Y ?
is it long enough to replace the cat and reach the stock muffler?
does it have a bolt on flange on the end ?
does it have a bung for the rear O2?
