You just can't!
This is like asking, "How can I gain 40 whp and keep my car stock?"

It just can't be done.

Yes. What the OP wants is impossible unless he gets some super small tips so that 2 tips come out to be the same size as one OEM tip.

Maybe I should revise the title of my post. I know that you cannot fit quads in the stock bumper without cutting it. I definitely won't be doing that. I want quads without going any extremes. After seeing this picture, I feel you still MAINTAIN a stock look with this diffuser or a replica.

Doesn't that Hamann diffuser require cutting the bumper for install? Which you didn't want to do.

Wow I really need to be specific here. What I don't want to do is widen the holes where the stock pipes are sitting just to make room for quads. I've seen some guys do that. No matter how straight you cut, it will still look like shit.

Cutting the bumper and putting a diffuser over top of the hole will look proper. You won't even see the cuts.

Anyone agree with me?

This is the best way to go IMO. If you don't like the cf look I believe Cyba and Adamaster offer an alternative for those that want to paint it to make it look OEM.

I see your point.
Well, yes, the best way is to get a completely new bumper if you wan tit to look stock.

Hamann, Bastuck or Mtech is the only way you can go. You'd have to cut the stock or aero rear and IMHO, just a cut looks cheapy unless its 100% perfect.

Why can't I install a diffuser on the stock bumper? wont a diffuser cover the cuts and make it look like it is part of the bumper?

imaznumkay and I have the same rear setup as you see above, its the stock bumper cut and then the diffusor placed on top to look like its part of the bumper. Hamann works the same way but its more expensive. I think there are replicas of that though.

Hamann replica. Looks strange, but painted same color as car, it'll look good : http://www.e90post.com/forums/showthread.php?t=160819

What kind of diffuser are you using? I really like the Hamann diffuser, but Adamaster and Cyba make replicas that are a lot cheaper. I'll probably go that route. I do appreciate your guys assistance on this. I wasn't really sure how this all works until today!!!

Bastuck. With a CSL trunk, its really hot, but even without one its sweet. Go with the replicas if thats your route. You can't go wrong no matter which route you go. Just make sure whatever quads you use fit in the diffusors.

Yea thats been my #1 concern. Although Cyba has a whole thread dedicated to diffusers and tips. I might wait to see what Dimisia comes out with for quads. If they are smart, they will make them fit these Hamann style diffusers.
