Also, based on the Hamann diffuser I could also shorten the 335 diffuser(s) to just wrap the exhaust openings - that could look a bit better, rather than having it span the length as the non-335 would have to...

I like those layouts. So are we looking at 6 months down the road to start production on a diffuser? I want to know prices and when this can get going.

Yeah - 6 months is probably realistic. I'm going to push to get it done quicker than that though. So far pre-LCI, single cutout seems to be winning the priority race, so I'll look into that one first.

As soon as the m-tech diffuser is completed I'll be registering as a vendor and then will discuss pricing on both - that should be relatively soon - within the next few weeks...

Ok I'm defiantly ready to do deposit and such when it gets going... The only thing is I want dual cut outs... Anyways I will try to do a couple photoshops when I get home.

+1 The third one is nice, but I have a 330i

Can someone do the same for a 330 with single exhaust to see how it looks?
Thanks

I think its a good idea

But just seems a bit to long of course only because we are use to seeing oem diffuser.

I would be interested In the diffuser for a single exhaust cut out

But what if you was able to make a diffuser that would make the rear of a 330/328 look like a 335 instead of the slot being so big and fitting two tips make the diffuser so it can over one tip and with a custom exhaust run it to the other side with another tip so it would look like a 335 instead of the quad set up

I feel like quad set up Is to far apart on non-335

Thumbs up

Non-335, Pre-LCI, single cut-out, matte-black

approximately how much would this cost?

It would be an interesting project but not very easy to pull off... The problem being that you'd need to make the diffuser big enough to cover the existing opening in the bumper and then you'd need to cut your bumper for the 335 positioned tips... Might work out quite expensive in the long run especially considering the custom exhaust.

Got you details - as for pricing, can't discuss pricing yet as I'm not a vendor on the forum. Will be soon though, so just stay on the lookout...

You mean a Photoshop of the 3rd one? I'll see what I can come up with...

As for the final product, the prevailing priority at the moment is for the singe opening non-335, so unless that changes soon it's more than likely the case that I'll do that first...

Hows this?

I think the tips aren't exactly the right size, but it should give a bit of an idea

Now were talking!!
How would it look if you go up a little more? Just up to the where the bumper starts to shape in.
Thanks

Depending on pricing, I'd be interested in one for a non-335, single cut-out.

Im sorry just dont l just dont like how its a bubble around the exhasust. Looks goofy. I think there should be a small round lip around the outside and the line following the oem bumper looks good. And then add the option of 3 fins between the duals.

Hey klove

Like I say my photoshop skills aren't wonderful - I didn't mean for the lip to be that big. I spent a bit more time - how's this one? This is probably closer to what I had in mind anyway. I'd definitely follow the lines of the OEM bumper and just create the lip along it's lines.

Agreed - that perhaps the fins would only look good on a dual (as in 335 standard) or quad (either 335 or dual 330 and down) setup...

For now the prevailing appetite is for pre-LCI, non-335, single cut-out, no fins...

I thought of that but I reckon it would be a bit too high in this case. I thought that if I hit the crease nicely then it should look ok - any higher would probably cause a bit of problems trying to get the rounded edge shape as well as the kink in the bumper right...

Problem is that this one is for the m-tech. It would be cool to put the slot and shape in but the issue there is the existing bumper. I could do something like this but it would definitely require cutting the bumper and I'm trying to avoid that so that it's as "direct" bolt-on as possible.

I can have it come down lower than the bumper a bit and include a horizontal slot like this one does if people reckon it's a good idea...
