Keep the mufflers you love or change the whole sound
Your Camaro exhaust upgrade can retain the factory mufflers or include Kooks oval mufflers and polished dual tips. These header-back packages complete matching Kooks long tube headers for the SS LT1 from 2016-2024 and ZL1 LT4 from 2017-2024. Choose how much of the exhaust you want to change, with the supplied parts and rear connection clearly shown by SKU.
SKUs: 22605181, 22605301, 22605381
Retain the factory mufflers
The factory-muffler versions use a 3" to 2-3/4" rear connection. The original exhaust must be cut to fit those connections. Choose GREEN catalysts or the Competition Only catalyst-free version, then have the installer align the system and complete the factory-muffler connection.
Choose the full Kooks oval-muffler system
The complete GREEN version includes the catted X-pipe arrangement, full 3" rear exhaust, Kooks oval mufflers, polished dual tips and clamps. It changes the rear mufflers as well as the front pipework, giving you a fuller exhaust upgrade in one package.
Start with the correct long tube headers
All three packages require matching Kooks headers, which are purchased separately. They do not connect to factory manifolds. Plan the calibration around the selected header, catalyst and rear-exhaust combination, with professional fitting and a first heat-cycle fastener check.
