    Any base non S-line A3’s looking for an S3 rear diffuser?

    Tried my luck on an eBay diffuser. I have an A3 with the base bumper. I have the BK Motorsport RS3 front bumper (pre facelift) and oem RS3 side skirts, so yeah...the base A3 rear bumper/diffuser looked out of place...to me at-least. This diffuser fit 100% oem. Seriously perfect fit. Just a heads up if you want to add quad exhaust to you base A3.

    Video of product and install.

    I have something similar but like it with my aftermarket exhaust. Stock exhaust looks anemic.

    I thought about a carbon diffuser, but thought the OEM S3 was a little cleaner. I’ll admit fast it looks baddd with oem exhaust. Though I have a set of 4” quads that were supposed to be delivered yesterday. (eBay guaranteed) sad when you pay $160 for tips and they’re late and no one knows where they’re at and tracking hasn’t updated once. Lol

    Like those wheels btw.

    I just kept the stock catback and had my friend weld on new tips. They sell RS oval tips.

    I love this total set up. Where can I find the tips?

    Found the oval tips, however, I need ones that are side inlets that aren't as much as a stock exhaust. Plus I want to electronically valve the system so I can make it quieter.
