Give your GT500 the exhaust character you want
Upgrade your supercharged 5.4-litre GT500 with Kooks headers and a GREEN catted crossover, while choosing the primary size and crossover style that suit your car. Both 1-3/4" and 1-7/8" headers are available with X-pipe or H-pipe connections to the OEM rear exhaust.
SKUs: 1132H230, 1132H260, 1132H430, 1132H460
Choose the crossover you prefer
The X-pipe merges the banks and generally gives a smoother, higher-pitched character. The H-pipe balances the banks through a connecting tube and is associated with a deeper muscle-car tone. Your rear silencers and the rest of the system influence the final sound too.
Matched to the earlier GT500
All four combinations use 3" collectors and a 2-1/2" rear outlet for the 2007-2010 factory interface. That rear connection differs from the later 2011-2014 GT500 kits, so choose the package around your generation as well as your desired primary size.
