I would like your opinion.
I am undecided; should I put headers or not. The end result is 650+ rwhp.
I have heard good and bad things about them. Like the bolts backing out.

 

I say no because it may take away that classic mustang sound.

 

Yes, get them. I haven't heard anything bad about them. And get the long tube. The shorties don't give as much power.

 

Get them. It's a quick way to add power.

 

Get em! Just to warn you though, I've heard that when you add freeflowing exhaust parts, like headers and X/H pipes you will lose a little acceleration, but gain more top end. Also I'd suggest that you check into local smog laws, they can really cause headaches come time to smog your Stang'.

 

If you keep the cats on then it should still have enough back pressure for bottom end power..
