Question DTM exhaust -- why turned up tips?

Is there a reason why DTM exhausts have their tips turned up?

A friend of a friend (heh) claims it is for increased downforce. I dunno who this guy is...

If this isn't the function, what is?

Greg.

I'm guessing just for the looks. Sure looks better than having them turned downwards!

Maybe so they don't scrape the ground when they back the cars off the trailer?

Wow, you guys sure came up with the goods, especially Colin. I'm amazed by the level of technical knowledge that was bestowed upon this post.

Anyways, the guys at bimmer.org's E30 M3 message board say it's to do with either:

a) preventing the exhaust flow from kicking up rocks and debris at other cars.
b) preventing the exhaust from being inhaled directly by a close following car.
c) improving exhaust scavaging by placing the tips in a low pressure zone (?!).
d) collecting rainwater.
e) looking DTM.

heh.

I dunno. Take your pick.

Greg.

I think it's just for looks and don't care for them. Besides, if you got water in your muffler, wouldn't that be a bad thing???
Again, just my opinion.

I think its looks. Come on now...who cares if your opponent behind you gets a little rock thrown up at him, or if he smells your putrid exhaust gas?

I would imagine that it would be to have a louder apparent sound to other drivers.

Wouldn't the fact that they are aimed higher increase the noticed sound levels ?

Greg, C) and E) seem most plausible to me.

I still think they just wanna look like top fuel / funny car zoomies.

Wow, it seems like nobody anywhere can agree on this one

Heh, I'm starting to edge towards "for looks"

Default Rain Collector?

Actually, they don't collect water. They have small holes at the bottom of the bend to let any "collected water" out. As for a reason why the tips bend up I have no idea. I'm thinking the looks one is likely correct. I have a DTM exhaust on my 1991 BMW 318is. It was installed by the guy who had the car before me. I would not have picked this system on my own as it quite noisy to say the least. I'm getting use to it now though.

Please smack your friend. I cant possibly believe anyone would be stupid enough to actually believe it creates downforce.

Please kill him before he breeds

BTW you know that DTM stands for "dual tipped muffler" right? It has NOTHING to do with the race cars.
The cars in that race series have exh that exit out the sides, in front of the rear wheel. I cant believe no one knows this. And you call yourselves car guys

DTM stands for the German Touring Car series (Deutschen Tourenwagen Masters). These touring cars use extensive bodywork. My best guess is that the upturned tips follow the contours of the rear venturis and allow them to create downforce more efficiently.

No really.. it's all about looks. Exhaust pipes nestled up against the bodywork look best.

THEY DONT HAVE UPTURNED TIPS, THEY HAVE SIDE EXIT EXH, WITH STRAIGHT EXITS

JEEZ...

Yes it does stand for Deutschen Tourenwagen Masters. However, on the mufflers, it stands for dual tip muffler. Its just the idiots on vortex that like to think they have race cars that are associating it with the race series.

I just got a DTM style muffler....

I didn't want mine to look like most others w/ cannon exhaust, the two tips are small and fit the bodystyle of the WRX I think, muffler tucks up nice and tips go w/ bumper angle, wish I had pics up to show...
