07 exhaust on 14 work??

[jeromebuchanan0323]

Will a exhaust off a 07 Silverado LS fit on a 2014 Silverado WT? Really just need both front catalytic converters back to the start of the third converter. Please help

It won't work. The engines aren't the same, one is a LS engine and the other is a LT engine. The exhaust manifolds and bolt locations aren't the same. Plus you have different transmissions and cross member locations.

 

You could cut the cats off and weld them onto the 2014's exhaust but don't be shocked if you still get a check engine light. The cats off the 2007 are not the same "spec" as the ones required on 2014 model year truck, so it may still give you cats codes after a while.
