Question about 2005 Chevrolet Avalanche
There's no guarantee that it will cure your code p0420. It's dependent on back pressure and factory settings vs the exhaust package you put on. Is there a possible waiver you can get from base? Based on vehicles age you might have that option. I'm not that familiar with military emission rules, but lots of states offer a waiver option. Wouldn't hurt to ask before throwing a handful of parts at it.
