You could go purchase some magnaflow hi flow cats, or get even wilder with some dynatech headers that include hi flow cats, and then go purchase a new cat back exhaust and youll awake that beast up. Dont forget a tune if you go all out.

i need new cats for my truck how should i go about this????

Why :confused: Your cats should not fail unless you have modified something to make the motor 'cat unfriendly'; what I am saying is that I worry you will install replacement cats and burn them out too unless the cause is determined.

How many miles are on your truck? Your cats are warrantied for 8 years/80,000 miles by Federal mandate. If you are within that time frame, your dealer should replace them FOC........


+1 Sean. What mods are done to the truck? How do you know it is the cat? One word of advise take anything off before you go to the dealer, or they may not cover it. Throw up some info so we know whats going on
