Gt14

Wondering if anyone has done this and how it turned out? I have a base gt and was wanting to do it because of the build I want to do. Seems rather simple if it's a premium which I don't have the luxury of.

Also would it be better to just buy a bumper cover with everything already? (Which seems impossible to find).

If you are talking a '14 (S197) car, the rear bumper for base and premium should be the same. The '15 and newer are different and looks like only the premiums can have their lower valence swapped out.

The '14 is easy. Remove the bumper cover and you'll find that Ford has the backside of the bumper pre-marked where you need to cut. Then just add the '13-14 GT500 lower valence and the bumper is complete.

Late Model Restorations sells the valence and quads as a kit.

Just buy the gt500 diffuser and quad muffs. You will have to cut off your lower bumper in order to get the diffuser to fit and its easy since i just did it a few weeks ago.
You will have to remove the bumper and on the backside it has a line that you trace to cut the lower section off.

Do you mean the quad tips on the rear or the Boss style quad exhaust?

If you install the gt500 quad diffuser, you will be able to run most quad tip mufflers. So yes quad tips.
Are you wanting the boss set up with side and rear exits?

Maybe this is what you want

Hands down one of the best mods I have done and I have a v6. Sounds great. All you have to do is get the rear lower valance for the gt500, and the axle backs. Then cut in to your bumper to make space, the lines are already there for the cuts you just have to follow them not hard at all.
