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.
Precat Deletes
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
Highflow precats
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

According to picture, you have to add the Magnaflow 10426 in front of the OEM resonator to reduce the PCD rasp? You don't replace the OEM resonator with the Magnaflow?
Are you offering a Tax Return Sale on the Jpipe & (HFC/PCD) combo?

The combo is always on sale. Cheaper then the tax return sale price.

Are there any vids/sound clips of
PCDs
(stock or RV6 jpipe)
Magnaflow 10426
remainder of stock catback exhaust?
I'm definitely interested in the PCDs; I just don't want any rasp. I assume the HFPCs do not have any rasp at all?

Where do you get the ceramic coating done?
Is it possible to get an actual thermal/satin coating rather than the metallic/shiny coating?
Any experience with coating the HFPCs?
My main goal is to maximally reduce underhood temps.

The shiny ceramic is just the satin coating polished up its the same stuff. I figured to keep things simple I would just have everything done in baller chrome.
Yup, we have done HFPCs not a big deal. Just a little more expensive since they have to plug the cores during the coating and polishing.
Yes, you will notice the gains from HFPCs or PCDs at least 10WHP.
Out of all of the ceramic coated PCDs/HFPCs that you've sold, has anyone complained about the internal coating outgassing/burning off and destroying the O2 sensors? Most likely, the downstream sensors?

I don't think it will be a problem since these are fully cured in a oven before shipping. I guess most powder coating places do no have a oven hot enough to fully cure the ceramic coating. So they tell you to finish curing on the car by letting the car idle for x minutes. These places you should avoid since the coating can burn off if you don't do it properly.

Richie I saw some of your products in their FULL glory (BostonSilverTypeS) for the first time last night and I'm impressed! I'm still in the research phase but I'm definitely leaning towards RV6 for my exhaust mods

^I'm interested as well, but I don't think there's any actual dyno testing done between the PCDs and HFPCs, specifically.
I've heard speculation that the difference is <10whp (5-6whp?). However, I believe the more important aspect to look at is the difference between the retained engine bay heat of both parts. A vehicle with HFPCs will be more likely to pull timing (reduced power) as soon as the hot cats start affecting the intake air temperature.
OTOH, the use of close-coupled catalytic converters (precats) allows the engine to reach proper operating temperature much faster than a non-equipped vehicle.
