Could also route ducts in a dual hole bumper for the brakes and get one of the CF ducted headlights for the intake (if you are running a CSL, eventuri, or afe). I've been considering that route myself because it would at least be a little unique.

Personally, the dual-hole ruins the look for me, it just looks too "modified" and un-unique like any other car. I could see its use if you drop an S62 in (with the dual intakes) but otherwise the dual hole bumper ruins it for me. The asymmetry is what makes it look so timeless, and screams function over form (while the dual-hole looks like it's missing fog lights and reminds me of a 90's Cobra Mustang.) Personally, if I needed a dual hole bumper, I'd stick with the stock euro-bumper.


I suppose it is better than the bumper with no holes at all.

I don't know about your neck of the woods, but seeing an e46 M3 is pretty damn rare where I live. Outside of the forums, every bumper would be a unique sight to see where I live, especially the CSL bumper. I only know of one person with a CSL bumper in my state. The rest that I have seen are the stock US-spec bumpers or GTR-style F&F-style bumpers.

The same goes for the CSL boot lids. They might be plentiful on the forum, but they are almost non-existent on the roads where I live.

I'm located in CT but I've seen a couple cars with the bumper and several cars with the trunk. I wholeheartedly agree that the asymmetrical style of the CSL bumper is iconic and would be my preference as well. I love my euro bumper that I had installed in lieu of a US spec unit after an accident but I'm craving a more modified look now because so many of the cars in my area are stock (and verts).

Love that style of Mustang too!

I agree though, looks like one of the better 1-piece lips that I have seen as well. I still prefer the splitters though.
Probably some local off-brand then.

Thanks for the input. As much as I like the CSL bumper, I will probably just keep the stock one, because I prefer having the brake ducting.
And adding the CSL style spltters to the stock bumper make it looks pretty close.

Funny. The splitters are what I don't like about the csl bumper and one of the bigger reasons I won't get one, even though I have an air box.

Form follows function. That front bumper and splitter combo helps to reduce front axle load by 83%.
