Soo option 1 : replace the secondary cats with high flow = ~10WHP
option 2 : replace the secondary and primary with high flow = ~20WHP?
option 3 : replce sec. cats and your headers (has primary included) = ~ 25WHP ?
My question was more about option 2 beacause we already discussed option 1 and 3...
thx

Hello Tony,
Each pair of high flow cats will free roughly 10 HP. Our headers make roughly 23HP/25TQ by themselves. How much they make all together is tough to predict exactly since nobody has done a direct dyno with all 3 combined but the gains should be very impressive to say the least I'm sure. However, you can't simply add 23 + 10 + 10, its not that simple. Realistically though 35-40HP should be possible for all three combined.
