So I've got my Boss valance, just looking for some advice on the best way to go about cutting this thing. All I currently have is a sawzall and a dremel. I know the sawzall will butcher it. The dremel I can see working well for the little tabs but being very tedious for the main cut from end to end. I don't have an air compressor at this point. Would a jigsaw work? I've seen some where the head rotates to a sawzall-type arrangement but with the finer blade and control that a jigsaw gives.

Thoughts?

 

I plan on using my 4.5 inch hand held grinder with a cut off wheel when I get mine, basically a Dremel with attitude.
I used the grinder when I did the Roush lower valance and it worked out pretty good.

 

There's videos on youtube. I just watched the one CJPP posted the other day. Doesn't look too difficult. I'm just afraid of the whole permanent part of it.

 

I used my Milwaukee cordless Hackzall for it. A fine blade of course. Worked like a charm.

I tried to use a dremel in my 06's bumper when I installed my chin spoiler. Because of the size of the cutting discs, the short shaft, and the size of the dremel body itself, it was A) very hard to get the dremel into the corners and B) very hard to make a consistently straight cut.

if your bumper is anything like mine, I don't think the jigsaw will really work either. the only time I've ever used a jigsaw was yesterday, but just based on that, I don't think the blades are going to be long enough for you to get in there.

a grinder with a cutting wheel or a hand saw would probably be the way I'd go

 

I ran across that yesterday actually. Pretty straight forward. For me it's more about tooling since a body saw isn't really an option due to lack of air.

I generally shy away from permanent mods as well, so I share your fears. But this one just looks so much better and has the look I'm going for on my car. Even if you butcher the cutting, the valance hides it all. So I finally decided just to go for it.

 

used this on my 13 rear bumper to prep for the boss diffuser. Worked like a charm. Make sure you have extra blades because they get gunked up with the plastic and become useless.

I just picked up a set of GT500 quad axlebacks and will be installing the GT500 valence. It looks pretty straightforward. My plan is to use my dremel unless I can get something better.

 

Thanks for the link!

 

That's how I installed mine. It took forever, especially if you're doing it alone. When the bumper is off the car, it's very flimsy and hard to hold steady by yourself while you're cutting. I drilled 1/4" holes all along the line, which helped speed it up quite a bit.

 

Oh good call, play connect the dots. I like that idea.

 

I had planned on drilling some starter holes too.

 

I used my reciprocating saw with a fine blade. I just made sure the cutting line was highlighted with a silver sharpie, so it stood out.
For the holes for the tabs, I just used a small drill, and a file to clean it up.
The new rear valance actually covers up the cutting lines and the holes for the tabs. It is all relatively easy to do, as long as you take the time.

 

Guys, I used a retractable razor knife. I started out using a jig saw but that required a lot of clean up and wasn't cutting as clean a cut as I wanted. A new blade and a slow steady hand left beautiful cuts that needed no clean up and very accurate cuts. Just take your time and move the blade slowly and you'll be done with the cut and clean up sooner than using a body saw, jigsaw, etc.

 

Great Idea.

Do you have any pictures before and after?

 

Only before and after on the car. Just think how cleanly a razor cuts things. No burs or jagged edges. The retractable razor blade isn't the cheaper snap off type blades that are for light duty work. I used the heavy duty blade seen below.

 

^^^ Never in a million years would I have thought I am taking a razor blade to my 2014 Mustang! But I will give the heady duty retractable razor blade a try once I get my rear diffuser in.

 

I gotta tell you, the razor blade worked so much better than the jig saw I tried first. The jig saw has the potential to scratch the surrounding painted areas and runs so fast, it melts the bumper as it cuts leaving a big mess and requiring a file to clean up. The accuracy and precision cutting of the knife made me question why I didn't start with that.

 

Scott... You made me re think mufflers... **** You. I thought about not cutting the rear because I could not get a clean cut.. I was set to order the single out Gt 500 mufflers.... Well then you post this and now I am re thinking everything...

 

You don't have to worry about how clean the cut is. There is a lot of room for errors. In fact even if you don't clean up the cut, it is no big deal.
You see, the rear valance actually mounts on top of the bumper so to say. It hides the cut completely. As long as you're somewhat close to the line it's going to be ok!
