2012 tacoma baja edition. would a y-pipe or long tube headers from URD, which would yield better HP and Torque. i want to keep at least two of my Catalytic Converters...anyone have any pointers?

Long tubes delete the front cats and a y pipe deletes the rears. Both would reduce low end power but open up top end.

I'm not sure what standards NV has but if they do a visual, you won't pass with either item.

Long tubes would be my choice if I had to pick between the 2.

Heres my opinion. Get the y-pipe. Opening up the exhaust system starting at the headers is backwards. Ideally, start with a cat-back exhaust system, then more towards the block. Going in the reverse order will only cause the additional airflow to bottleneck as it reaches the next restrictive portion of the whole system.

The further from the exhaust valve, the greater the volume and the corresponding velocity drop. So, restriction matters less at the tailpipe than the header.

That's why a muffler or cat back don't make the same gains as headers unless they are usually restrictive.

Exactly but you're not going to get the full potential of the headers if the rest of the exhaust can't flow the extra air. Thats pretty well understood.

OP, given your post, which is asking one OR the other, headers are the one. Proven gains at mid to high rpm levels, might cost some low though (dyno shows loss, but any actual upgraders that report a loss are minimal). The y-pipe, while good, does not have any documetned gains by themselves that I have seen. Good part of an upgrade plan if that's where you want to go, but by itself.....

BTW Chris, my opinion on order is different as I would upgrade parts one-by-one based on the biggest improvement for the $$$ I have. Given that, I would do headers, Y, catback (or just upgrade the muffler if I am staying NA and not racing). I understand what you are saying, but I would pop on the biggest improvement first and go from there.

ok so i decided to go with the Y-Pipe. Because the o2 sensors only monitor the front Cats near the headers. So the Cats connected to the Y-pipe basically arent doing much haha...so with a CAI, URD Y-Pipe, and TRD exhuast should i yield some good performance???

Once again, short tube headers FTMFW

It's power in an RPM range you'll actually use daily. Plus, all cats stay in place so no issues with emissions or CEL's.

Yes, you'll keep the front cats but I don't know what coupling the Y-pipe with short tubes gains you. Short tubes gives you gains in the low to middle RPM range. I'm not sure what happens when you put a less restrictive Y-pipe behind the shortys does for you.
