Featuring Magnaflow's new metallic substrate core. Less weight, more durability, and higher flow than your standard ceramic substrate "high flow cat". Do not confuse these with cheap Chinese made ceramic substrate versions! These are very high quality parts made proudly in the USA by our expert fabricators.
Our test data shows that this cat flows 87% as well as a test pipe vs. 43% for the OEM Cat. High flow and no test pipe smell. You can have the best of both worlds. Includes new 3 bolt gasket & nuts/bolts. As of January 1st, 2009, performance high flow cats are intended for off-road use only in the state of California.
