Would anyone want a free set of ARH long tube headers?

I think factory cats are 400 cell, maybe more and the one on system is now 200 cell (very high flowing cats) so there are emission increased.
Yes, I am rocking stock exhaust. When you get on it, then you can hear more volume from engine. I might put in an high performance muffler (no drone but louder) to utilize the sounds better.
I had 150 a miles drive home. I will reset the PCM an see what happens. The check engine light actually came on while I was heading home.

Is there enough room under there to fit cats that aren't part of the ARH Y pipe right at the collector? I don't really like the placement of the stock cats on the 2500..... they're in such a weird place.

It was for both bank catalyst efficiency. I reset the PCM like an hour ago (adaptions) and will see if check engine light will come back on.

That's what I'm getting currently.... I have exhaust leaks though, which is why I suspect that's happening..
little concerned about getting headers now though....

I wouldn't. If you have a tuner on your truck then you should able to trick PCM that theres cats in the system. I can always put o2 spacers on it to turn off the check engine light. By the way, the check engine light came back on today, probably for cat converters.

I'll figure something out though, as I said before I probably won't be able to get the exhaust system done until September unfortunately, and it's only unfortunate because I'm getting like 9mpg right now with the exhaust leaks I have.
do you think there's room to fit 2.5" cats right off the collectors? I'm waiting on the PaceSetter 80-0016 converters, which won't be here until roughly the end of august, so I hope I don't have to return them, because I'm buying the ARH set without cats......or maybe I should just get the catted set and figure out how to go dual from there??
I really don't know which direction I want to go. We don't do e-testing here any more, but I don't want to go catless in case it ever becomes an issue somewhere.

Seems like a waste of $ to buy their y pipe if you don't intend to use it. In general $1900 is seems like alot to spend on headers. They are stainless, so they won't rust - but they may crack over time. I'd be tempted to get some repro exhaust manifolds and spend the rest elsewhere.... Its a 3/4 ton truck, and the as 04HEMI04 says, it is noticeable in the higher rpm range. How often you racing this 3/4 ton 4x4?

Did you get a tune on your truck yet? If not how's it been running after the header install? Any better mileage or anything?
