Header Options

[Z-56 Hoe]

DynoTech long tubes with their free flow cats and Y Pipe a little pricy. But. My muffler went on with out a problem. Oh and worth every penny same headers have been under my hood for 10 years and on two 5.3L's and three 6.0Ls engines.

Kooks are good too. Shortys don't do anything for these LS motors unless they are flipped unside down to a turbo!

I personally bought the american racing headers long tubes with off road mid pipes. Yes they are pricey but the fit was amazing! Fit like it was factory! They are stainless steel so you dont have to worry about rusting. They have excellent customer service! I actually talked to the owner him self at one point! He was a nice guy and very helpful!

For a cat back kit i went with corsa performance. Once again a little pricey. The fit was also like a factory fit! It is stainless steel also! Every thing about there kit was awsome!

The complete exhaust system is now stainless steel. Never have to worry about it rusting out. The fit of everything was like a factory fit. The two kits worked perfectly together! No modifications need anywhere. Yes i payed more than most people would for my setup. It sounds super mean though! Would i do anything differant if i had to do it again? No.

A little over priced for what you get. I have Dyno Tech Long tubes same price
But come with free flow cats and Y pipe and are Ceramic coated.

Apples 'n oranges. The ARH headers run merge collectors and will out perform the Dyno Techs hands down...

Ok. Sounds great. So how is the tone and what is your before LTs BHP #'s and after LT BHP #'s and of course torque

Not trying to be a dick just really wanna know? I have had mine on truck for almost ten years and through a few engines so. Mine aren't going anywhere but I'd be interested to know looking at a new 2014 Silvrado.

I had American Racing Headers on my Denali and the fit was awesome. They also offer a y-pipe to bolt up to the factory exhaust location if you want.
