Here is a link to some pictures of my new exhaust on my 99 f-150 with the 5.4
It has a si do flowmaster with 2.5 inch pipe and 3.5 inch black chrome stainless tips.

Looks good. I've never seen a black chrome tip in person.

 

Looks good, hows it sound?

 

It sounds real good under a load. It is a little quiet at idle and while going down the road at 1500 rpm. but that isnt a bad thing either. I'll give it a couple hundred miles to let the muffler break in and see if i want it any louder. If i do i might go with a cold air intake to improve it.

 

If you want it louder then go with the high flow cats.

 

Nice congrats.

 

or no cats at all like me

 

x2 on the high flows, no CEL, no rough running, sounds that much better. much better flowing i have a si/do flomaster, put in magna flow high flows and its great.
