Possibly time for another upgrade or 2, so far ive done intake , tune , axle back exhaust, my next item is going to be a short throw shifter. For the question since i'm not exactly an expert on the 4.6 yet , Will it be worth it to do headers and throttle body alone , or is it a waste if i'm not doing cams and the whole nine yards?

 

Headers=YES...throttle body, not worth it!

 

If you want your car to sound like a beast...........yes, do long tubes! TB no way.

 

The TB would be worth a little IF you did cams and LT's. Unless I did both, I wouldn't bother with the TB. I probably wouldn't bother with it even AFTER cams and LT's.

Consider UDP's or an aluminum DS. Either one will free-up about 3-5 RWHP. I've also heard good things about an electric water pump freeing up 5 or more RWHP. But as you add RWHP the stock tires/suspension won't cut it so consider new, wider rubber and suspension mods.

 

But if you DO decide on a TB, be sure to add the TB spacer... Just so we can needle you more. LOL!

 

If you're doing a shifter, be sure to check out MGW. Best by far.

 

Shifter MGW, don't even look at anything else. LT's YES!! American Racing or atleast Kooks, don't bother with that Chinese made garbage they will fail eventually. TB Sure, why not I added a GT-500 and felt a difference without a tune, most people don't like them because they cost a lot but to me anytime you add more air you make more power. Stay away from BBK and get a FRPP product being they come with new electronics and they are a direct bolt on.

 

My vote for nest mod:

Street= gears
track=tires

or both
