This: http://www.jegs.com/i/JEGS-Performan...oductId=758633 says its for 94-99, but is there any reason it wouldnt work on a 2001. I have seen other exhaust stuff that says 94-01.

 

I think that's because the 2000 and 01's have a different pipe size. I suppose it would work if you are replacing the whole exhaust. I'm sure someone that has used one will chime in. This may help with the pipe sizes. https://dodgeforum.com/forum/2nd-gen...ram-1500s.html

 

From what ive read on the subject in 2000 the ram gained 15 hp over the previous years, with the only change being the exhaust y-pipe, before the y on the 99 ram the pipe was 2.25", on the 01's its 2.5".
after the y on the 99 is 2.5", on the 01's I think it was 3".

The jegs y-pipe has 2" pipe before the y and 3" pipe after, also theres no cat and less restricted/ free flowing.

Its been a while since ive finished my exhaust system so the pipe sizes might vary slightly!

 

So is it really worth replacing the y-pipe on a 2001 or should i just remove the cat?
BTW, we dont have emissions testing here.

 

Personally, I'd replace just the cat(universal) with one of the right size. If your Y is fine and not rotted, it is a cheaper and more environment friendly.

 

Well I dont want a cat and I heard the y-pipe is a big restriction, so I thought maybe kill two birds with one stone, but if there wouldn't be much of a power gain with the jegs pipe then i might as well just take off the cat and leave the stock Y.

 

If you delete your cat would you not have CEL and considering the 2 O2 sensors read what the cat is doing, would there not be any drivability issues?

 

You would have a CEL that would say "Your cat is not working" because the DOWNSTREAM O2 sensor (one after the cat) will cause the CEL.

It will have no effect on the precat O2 sensor since it is...well...precat. Thus no driveability issues. Only if the precat O2 sensor is taken off or not working properly you will have issues.

 

The factory Y on a 2001 is not a big restriction like on earlier models.

 

I heard about having two spark plug non-foulers in the O2 bung and the O2 screwed in them. Does this trick actually work?
