Diamond Eye HX40 4" 2x4 Turbo Back With Muffler - K4209A-HX40

This system from Diamond Eye is designed and built specifically for those that have upgraded to a larger turbo featuring an HX40 style downpipe in your 1st gen Cummins. Eliminate the necessity of buying a complete exhaust system, and then an HX40 downpipe all while enjoying all the perks of a Diamond Eye system. NOTE This system will NOT work with a factory turbo, you MUST have a turbo featuring an HX40 style discharge. Please contact us if you have any questions about proper application.
