Coated header really work?
I have a 1993 GMC SOnoma that has a 5.7L TPI shoe horned into it. As you can imagine, underhood temperatures are a killer. I've read that ceramic coated header are suppose too help keep underhood temperatures down.
Is this true, and can it cause a hot spot where the headers join with the uncoated exhaust?
Thanks guys
Josh

Re: Coated header really work?
Well worth it. It keeps the heat in the headers. Once you shut the engine off with in 10min or so You can grab a heater.
Just make sure whoever does them for you does INSIDE and out.
