Headers - Ordered - Discuss install and options

[pdxrealtor]

There's been a lot of talk about headers lately, but I haven't seen anyone pull the trigger or any serious talk of complete setups, installation setbacks, etc..

So I'd like to get this all in place.

I ordered the OBX with cats found here :

My first question is will I loose much by keeping the OEM muffler on the truck? I'm really not after sound, I like it quiet. I like to save money. I don't like to lose out on performance so if I have to I'll weld in a high flow muffler into the existing cat back setup. Why change the OEM pipes? Last thing I want is dual tips hanging out of the back where they obviously aren't meant to be. I like mine nice and hidden.

Any tips for installation? I've read use GM gaskets and bolts. Yes? No? What about high temp red sealant on gaskets and connection points?

Haven't looked into having these ceramic coated but have thought about it if the price is right. Thoughts?

Chip after install? Heard it's worth it. Who does them and which ones are known to be better?

Any other thoughts or advice?
