I would suggest that you start saving your money for head gaskets and when you have them done, have a machine shop open up the heads for better flow.
You could throw a snorkle on your truck and at least bring in little more cooler air. Whatever you do, do not install a K&N air filter, it will kill your MAF.
As for the exhaust, you can spend alot of money for a Borla but you will only get a couple of extra horse power.
What is the mileage on your truck, if you are over 100,000 miles replace your 4O2 sensors to regain some lost power.
Then do a good engine flush, and induction cleaning and a t/body cleaning, this will help with the power.
By the way, are you still running the original plug wires?

The only problem that im having with the gaskets is a little oil leaking around the...what i think may be the head gasket. Sry ive never been a gear head, but what do they need to do to open up the heads? As for the exhaust, i dont plan on spending alot for a Borla, but i do plan on running duel pipes out the back to help her breathe a little easier, maybe just throwing on some decent Flowmasters for a good deep sound. And what do they need to do to flush the engine and clean the induction and tbody...how much would that cost? and as for the plug wires, im not exactly sure, i know im at least the 3rd owner including the dealer, so i am probably still using the same plug wires. i know the plugs and wires could use a change, but recently ive had to fix the cat on her and replace the rear air bags for the suspension...no money for the plugs yet.... ![Frown](https://landroverforums.com/forum/images/smilies/udbMv2o.png)

For opening up the heads they need to port them. Meaning they machine they head ports and make them, for lack of a better word, "Wider." This allows more air into the engine due to the wider ports. Oviously more air means more power. It is a pretty extensive and expensive job. And if you do something like that you will need to do the exhaust as well. Getting a lot of air in is worthless unless you can get that air out.

After reading that, I switched back to my stock setup. (but I miss the extra mpg)
I guess a better question would be, what would you do?
And just a tip for everyone who doesn't already know (I just found out), you can use google to search the forums for keywords like this:
your keywords site:landroverforums.com
This may be old news to some of you.. but I found answers to many questions using this.
