i need a pert number for a high flow cat for my 2000 dodge ram, i ordered the wrong one it was duel in single out, when they said its sopposed to be a 3 inch si/so. or something can someone help my out??? for some reason the high flow cats change for the yrs

 

Yeah, for some 2000 and 2001 model years the exhaust was changed changed but not documented to well.

That's the one I used. The difference between that one and the one on jason.w's truck is that this one is 3" shorter in the length. My local exhaust shop I got to do the rest of my exhaust didn't have any problems installing it. They did have to put a reducer on the rear as the pipe after it from the factory is 2.5". It was 3" going into the cat and 2.5" coming out. They just installed a reducer for me since I didn't want to run new pipes and my Flowmaster is a 2.5" inlet.

I think I paid $90 to have it put on then whatever it costs at Summit there. It was either $90 or $60 but I really think it was $90 I'm just not positive.

 

Here is mine installed.

 

lol now in confused , is it the same part number cat , what makes your diffrent other than being 3 inch shorter. did you see any benifits also??

 

It's just 3" shorter. I think that's the only difference. The shop installing it might need to add a little bit of pipe or something but either should work fine as long as a exhaust shop is installing it.

As to if I noticed a difference the sound changed slightly it sounds a little louder and more I guess raspier now idk how to explain it not really raspy. Anyway power wise it might have helped a tiny bit but not much. I don't know if I think it's worth the money unless your cat you have now is bad. Out of all the bolt ons I've done on 2 cars I can't say I've ever seen anything make much of a difference in power. I'm starting to think they just don't do much at all.

 

When a gentleman here (RM Indy) timed it, it increased his 1/4 mile time by .35 seconds over the stock cat. So definitely a marked increase. I had my exhaust (Super 44) and high flow done at the same time, so I can't personally compare them individually, performance wise. Together, they obviously made a big difference.

Before, I didn't know what part # I needed, so I just had my local Meineke shop put it on. $145. You can get it from Summit for just under $80, plus Summit's $10 handling charge, plus whatever shipping charge. So it was a decent price for a local shop, even if it was still a bit high. If I had known the part # ahead of time, I would have ordered it. I suggest you do as well, unless you can get one from your shop for $100 or less.
