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

What are the avg gains between the PCD and HFPC options?
Has anyone ever tried the PCD with a J-pipe and then a single high flow cat after the J-pipe and a custom exhaust to finish? Would that be better than the HFPC?

If you are going with a custom exhaust you could always have the cat welded in after the exhaust. I feel that the exhaust gases would be slowed down dramatically and negate the gains from the longer runners of the V3 jpipe.

To be honest no one has tested the HFPCs against the PCDs. Since we are using 200 cell race cats I don't see a huge difference.

Should be doing my shopping come spring.
