JAMO's Stainless Competition Exhaust Systems replace the entire exhaust from the downpipe back with 4" Stainless Steel straight pipe. They generally do not require welding or modification and install easily using OEM mounts and hanger locations. Better still, JAMO includes a stainless steel tip with every exhaust. JAMO is the new kid on the block, however they manufacture an exceptional stainless steel exhaust system at a lower price than Flo~Pro and aFe.


4" Mandrel Bent Stainless Steel Tubing


Every 4" JAMO Race Delete Exhaust System includes a polished stainless steel tip.


The Muffler Delete Pipe ensures the maximum exhaust flow and provides an aggressive sound.


Installs simply and securely using OEM mounts and hangers ensuring your exhaust will stay put once installed. The kit includes all the hardware required to get the job done.


While a free flowing delete exhaust will increase HP and torque performance, it also reduces EGTs and eliminates "Regen" resulting in a more efficient truck, too.
