Kooks headers no tune cause to lean?

If i install 2in kooks headers and catless midpipe will i be running to lean without a tune or will i be ok? This will be the only install as i have read if you add a inake you will for sure be lean and need a tune to correct A/F ratios.

Maybe. The only way to confirm the A/F ratio is dyno with a wide-band O2 sensor. Probably worth it.

You should get a tune when you upgrade to long tube headers. Peak performance will be compromised and you will activate a check engine light.
