    Who makes a rear diffuser for the C7?

    Guest-only advertisement. Register or Log In now!
    I don't know why I'm having so much trouble finding a rear diffuser. I have a 2015 Pre-Facelift A6 C7 S-Line.

    Everything I see is for the base model style bumper.

    I'm looking for a diffuser with cutouts for quad tips, or the RS6 style.

    Anyone have luck with any of these at a reasonable cost (Under $500)?

    You should search on eBay, I got an RS7 diffuser there for cheap. I've seen RS6 ones as well.

    exactly.. anyone have experience with them before I spend that much on something from china (Would be such a pain to return it)? especially fitment considering every listing uses the same pictures. I dont know if the A6L has the S-Line bumper.

    I literally said I got an RS7 diffuser there for cheap. I have a 2014 A7 and I got the RS7 replica and it fit perfectly... If you like I can send you the seller I bought it from. Just trying to be of some help

    Awesome man thanks.. That's perfect just needed like a good "referral" lol.

    They all use the same pictures, and so many are they make it point to say not for s-line etc. its confusing and risky.

    Thanks though, I'll contact this guy.

    I think I need this route. All listings still for non S-Line A6.

    Biggest question is will a C7 S6 diffuser match right up to a C7 A6 S-line?

    Correct, the EBay seller I gave you, his products should be good for any A6 bumper. Reach out and confirm with him
