Kooks Long Tube Headers

[Gene3]

I have a '24 GT premium with active exhaust and Whipple only exhaust mod is Roush X pipe. I have been reading and researching Kooks catless versus green cats. I decided to go catless because I live in the country, have no neighbors, and want the best performance. My only concern is tuning since it's not available. Will Whipple provide a tune for this set up, even at a fee? Should I not be worried about changing or needing a tune? Thanks for any advice. Gene

DerekBaranProductions on youtube has a video of his install with catless long tubes and I haven't see his have anything going on, there's also a video of a dark horse with the same set up, and I have the same setup too. You should get a sims card in the tomahawk that you send to Whipple a few days before then they send you a tune back off your cars file. Least that's what I seen. Don't thing there will be a fee. Should be fine with the headers and Whipple.

I have the whipple with catless Kooks headers. There is no tune just the whipple tune it came with. You just need the mod that makes the car think u have cats, my performance shop did it same time as whipple. I have no engine light on either.

That’s what I’m running. Just have the check engine light showing on the dash.

Can go to lathal performance ans get the o2 sensors and get that off. That's what I do.
