Long tube headers
I'm wondering if anyone has some good info on long tube headers for my 2013 Black Diamond Avalanche.. I don't know one brand or type from another.. Any recommendations on the remainder of the exhaust system also? Cats/Crossover pipes/Mufflers etc.. I was hoping for some tech advice in the, increased performance/fuel economy areas. Also, I've heard it should be dyno-tuned after installation - is that true? (Thanks in advance!)
