Ok I'm looking into buying an Escalade in the near future and I had a couple of questions.

1) The Escalade has a 6.0L LS1 correct?

2) Will it accept Long tube headers designed for a Camaro?

3) What bolt ons could I do besides headers and exhaust?

 

Let me rephrase #3.

3) Any SANE bolt ons I could do that wouldn't empty the piggy bank?

 

I have a Silverado SS with the 345 horse 6.0. You cannot use the headers designed for a camaro.
The best cheap mods would be:
muffler(stock exhaust is pretty good)
pcm tuned(really wakes up these trucks)
k&n filter(stock air box is not a weakness)

These are the only things I am doing to my truck. These trucks are not light. It is tough to make them fast. With these mods you may see high 13's, low 14's.

From the first link:

"It looks as if the LPE Escalade may join genital piercing and Toyota's new Scion brand on the list of things we just don't get."
