Like it says. Is the lower rear valance functional or just to hide the muffler?

Traps air, promotes lift at high speed.

Rear trunk mounted ducktail reduces lift.

It's a car designer's muffler cover. When the muffler isn't there it's an air dam and missing on track cars. I remember seeing a recent thread about some louvered factory valances but I'd consider stainless-screened grills if I thought it worth the effort for a nice street 914.

Like the rocker covers I like them to be the same color as the car. It lowers the "look" of the whole machine.

Non functional. I rather like the looks of guts, but if you don't, you could go to great efforts to hide those mufflers and maximize air flow. (IMG:style_emoticons/default/smile.gif)

None of the factory GT race cars ever used them. I imagine if it did anything besides adding weight they would have left them on.

Probably purely aesthetics but I happen to really like the look of the short valance on a Six or any 914. And, yes....I have a deep valance for my Six but the short will go on the car to allow the bottom half of the muffler to show.

I'm pretty sure it is not functional. It just brings the sight line down when looking at the car from the side. The rocker panel is only +/- 4.5 inches off the ground so by comparison the bumper looks jacked up without the valance. Since I don't have a rear valance on either of my teeners, I used high temp (1400 degree) paint and sprayed it flat black to minimize the shocking size of the muffler.

Its non functional, but the car tends to look unfinished without one, IMHO.

If I had one it would be... an overly complicated air-dam. (IMG:style_emoticons/default/beerchug.gif)

i'd taken mine off after a recent muffler replacement led to an exhaust tip that wasn't in exactly the same place (bursch to ansa). guess i'll be like the cool kids and just leave it off!

i'll agree with some of the others above though. the car looks a bit unfinished w/o...

Your humble opinion is echoed here!
Appreciate that it isn't for every 914, but every 914 thru 72 came with one...from the Factory.

And, I fully appreciate that the later valence was a smarter piece. But period correct is just that.

Modified cars aside.

I noticed an increase in stability with it off at high speeds.

I think it looks better with a valance, especially from the side. I also don't care to see the muffler. I do think air flow is better without it which is why the factory did not use them for the race cars. I wanted to hide my muffler, add a lower look to the car, and yet still allow air flow through to reduce lift and promote airflow for engine cooling.... So this is what I came up with.

This was the first version before I decided to improve the airflow. It definitely gave the lower lines I was after and hides the boxster muffler.

Side view. Valence will be painted black to match the bumper and rockers.
