I installed Kooks 1 7/8 Catless headers on my active exhaust 24. All I did was order a pair of o2 sensor spacers for around $15 and no CEL.
I have a list of questions for the header people

1. What did you notice performance-wise after header install? Any changes in the power/torque curve?
2. How significant was the sound increase?
3. How do you manage passing emissions with headers? lol

I didn’t dyno the car so can’t say too much about performance but I can say the throttle response is much better. I went catless headers and have steeda H pipes installed and the car is DUMMMMMMY loud lol. Cold starts are brutal. Thank god for active exhaust. And definitely not passing emissions with catless headers. I’m in Florida so it doesn’t matter to me lol

That all sounds great, but I'll have to find a shop to pay off for emissions šŸ˜†

I'm running the Corsa double H and I'm trying to decide between waiting on the roush axle-back or just getting headers, which will prob cost about the same in the end

1. My car gained over 4 MPH in the 1/4… so every bit of roughly 40 HP gain avg through the upper rpm band.

2. Sound isn’t too much louder… quiet works excellent still… stock resonator/catback.
I could assume a resonator delete would make me deaf.

3. Non emissions state.
