Need help finding performance headers for 2006 Acura TL 5AT
Hey guys, I've been wanting to upgrade my headers on my TL, but everywhere I look I have not been able to find aftermarket headers for my car. I'm starting to begin to think that they dont even make headers for the 06 TL. If anyone knows anything about aftermarket headers I would love the help!
they dont.
we have catalytic converters coming right off the heads.
So, we replace the cats with straight pipe.
which can be found here:

replacing those cats with straight pipe will lead to a failed emissions test if the following applies:
- does your state do emissions testing?
- defoulers are angled wrong
- o2 sensors are roughly handled.
- Sniffer test!
if these are met, your car will throw a check engine light and will not pass emissions.
without these primary catalytic converters in place, the car will also give off a funky smell.
think race car.
and sound pretty funky too!

re-read the stipulations.
Kingkong_dav came up with a really great point, RV6 also sells High flow cats on his website.
so, you could do HFC instead of PCDs and still pass
LOok at the website I provided

Another important component to consider is the j-pipe, which is after the pre-cats. It technically would be part of the headers on a Acura/Honda. It makes significant power.

Here is a quick RV6 crash course, this is rough draft that will eventually be added to the webpage. You can get more details on the rv6 website www.rv6-p.com
The order of exhaust components.
Heads (engine) > precats > Jpipe > 3rd cat > exhaust
Jpipe+3rd cat delete
The RV6 V3 jpipe is our latest design and has the best gains due to its 2.25" long runner design. It replaces both the factory jpipe and 3rd cat in one piece. No check engine lights are triggered since there are no sensors on the 3rd cat. It is recommended that you get the jpipe before PCDs or HFPCs.
Pros:
Good mid and high range gains
Replaces factory jpipe and 3rd cat in open piece
Bolts up no modifications needed
No obvious place for a 3rd cat.
Cons:
May not pass visual inspection in some states.
Precats
There are current 2 RV6 options for a precat replacement. These options are effective because Honda used a very restrictive precat design. They are made with stamped sheet metal to reduce cost and have a small 1.75" out.
Precat deletes or PCDs replace the factory precats with a straight pipe using smooth flowing castings a 2.25” outlet. Precat deletes include special adapters for the O2 sensors and do not throw a check engine light.
Pros:
Maximum performance gains
Low cost compared HFPCs
Cons:
Raspy exhaust
Exhaust smell
May not pass visual inspection
Requires an extra resonator for rasp free operation
High flow precats or HFPCs replaces the factory precats with high flow catalytic converters. They offer the best of compromise between performance and daily drivability. They are also paired with our smooth flowing castings 2.25” castings.
Pros:
No rasp
No exhaust smell
May pass visual inspection
Cons:
More expensive then PCDs
Slightly less power gains compared to PCDs

there are 2 different stock cats.
the base TL has a cat with a cell count of 900.
the type-s has a cat with a cell count of 600.
RV6's High flow cats have a cell count of 200-300.
Do the math
your Accord might have a different cell count.

And I'm pretty sure an Accord would have at least as restrictive a cat as a base TL...

for the Rv6 v3 PCD's. How does the lower cell count translate into power? I've seen dynos of the PCD's, don't recall seeing one with the high flow cats. My best guess would be maybe 60% of the gain of the PCD's?

Base TL's benefit MORE from a HIGH FLOW Primary cat than a TYpe-s would.
because you're going from a 900 cell cat to a 200-300 cell cat.
as opposed going from a 600 to a 200-300 cell cat
remember, a PCD is a straight pipe and would have nothing to restrict, so it would be the best gainer.
DO THE MATH!!!!
(because I'm too lazy too, and you're the one that wants to find the %)
and Honda doesnt hide the catalytic converter cell count information. Find your cell count and then compare.
