Finish your RAM header upgrade with the right Y-pipe
Connect your Kooks headers to the OEM rear exhaust on your 2019-2020 RAM DT 5.7 with a matching stainless Y-pipe. These Competition Only, Performance and GREEN options are specified for the Crew Cab short-bed truck with a 144.6" wheelbase.
SKUs: 35203100, 35203200, 35203300
Choose the catalyst for your HEMI
Performance cats suit a naturally aspirated engine. GREEN supports forced induction, while Competition Only supplies uncatted pipework for competition use. The front and rear pipe sizes are 3", with the OEM two-bolt flange at the rear.
Match the cab and wheelbase
All three Y-pipes here are for the Crew Cab short-bed 144.6" wheelbase layout. That dimension determines the fit, so use it alongside the year, DT chassis and 5.7-litre engine when choosing your connection pipes.
