Is there somewhere I can buy quad tips to replace the square tips on my 550? I don't want to replace the whole system just those square tips if possible?

Yes, it is possible. you may get "piecha design" , they sell just tips. And they are nice looking, if photo needed i can post. replace my cat back system.

please post photos

Okay,
will go for it today. I will place some photos tomorrow or today if i won't be busy.

Great. So I can JUST replace the tips? I don't want to replace anything past the tips.

Please post pics! Also how much and where did you buy it from?

Will these fit the standard rear apron o the 550?

Yeah they will need fitting on to the pipes that the 550 tips are connected to - which are bolted to the diffuser too. Should be suitable clearance for them, if not cut the diffuser piece a little

What about the E63 Tips? Does anyone here done that?

I believe those tips would look great on the E-coupe but not sure if its gonna fit:

lol, i seen exactly these tips for around $300.
Yeah, as Dr.Nab said tips will fit e350/550.
Btw, took photos, will upload them soon.

Good price.. where did you see it?

I saw this tips on JC Sportline web site. But never bought there anything.

Quad tips i bought from chrome-tec.com because i couldnt get in touch with piecha-design straight away.
The owner of chrome-tec.com is Patrick, very friendly guy, i bought staff from him, so you may say that David recomends you.
Here we go my photos.

Love those tips but no way I'm paying $800 for what is essentially $25 worth of metal.

Agreed, it is just simple replica tips, which can be found for 70$ here(similar shape) and graved amg logo on it. Ebay link

Hey Folks,

Went by my local custom exhaust shop today. They're going to work with me to come up with some stock looking tips for the exhausts. They're going to just tack weld or bolt them on so they can be removed when necessary.

Will post pics when it is completed.

still waiting for the pictures

here is a picture for you guys...

In my opinion I think the oval shape tips fit our coupe rear end better since our rear end is short it doesnt look so good with the square tips.

Those tips look out of place, IMO. You definitely need an aggressive diffuser and a spoiler to pull the AMG tips off.

the 550 looks sex-ay as is....350 looks like crap IMO

sick car man, what have you done?

Check out my thread " My 2012 Black E500 Coupe"

I too am also interested in quad tips for my 2012 E350 coupe (US). I don't really care if they are oval or square. What is the easiest and lest expensive option that looks decent?

Thanks
