So I am considering purchasing the package including tune, headers, and intake.

If I run high flow cats instead of going catless will I notice a big difference from my stock set up power wise?

I don't want to spend $2500 if it's not going to make that big of a difference.

All input is appreciated!!

It's not that big of a difference between catless and high flow cats. Here are the numbers from PPE's site.

The headers with no cats show a 38-46whp gain

The headers with high-flow cats show a 28-33whp gain

You will feel a major difference in the car with the performance package. Cats do hold back a few HP, but you won't notice.

Interested as well. I wonder if the tuned intake would increase power if you're running headers with high flow cats.

You will notice a huge difference in performance over stock either catted or without cats.

Nice! I'd love to see if the intake adds any power up a mile high... you gonna do before and after dynos?

MileHIFcar

Yea I got my before dynos already done, will definitely dyno after everything is put on

Do the high flow cats require any exhaust / header mods at all?
