S4 Stock Exhaust Schematics

[Highlander1010]

Hi All,

Does anyone have a link to or PDF of the Audi OEM specs on the S4 stock exhaust? I need to do some comparisions and I can't find anything in the search or on the web yet, but I've not given up.

Thanks,
Joel

What kind of info are you looking for?

Physical layout and hopefully dimensions as it matches up against an A4 avant. I'll do the leg work but cannot find an underside schematic, pn set or anything.

Doubt it would help but here's a shot of my stock exhaust. as for actual dimensions might be a little harder. Maybe try getting in touch with GMG. Pretty sure they're the ones who made a B8S4 Avant.

Thanks for the pic. I just picked up one this weekend with only 200 miles on it (was switched out for a Stasis set). Just trying to figure out how to compare to the A4 Avant setup. Searching out loud I suppose.

The Avant exhaust will bolt right on but you'll need to change your valance if your picking up the dual version.

The s4 exhaust would need to be butchered to try to get it to fit your A4 and even then it may not fit.

Not sure if this will help, but courtesy of APR.

Yup - I'm planning on butchering it at a well recommended shop nearby. I'll do a Y out of the resonator towards the downpipe and be keeping my APR Stage II in tact while removing the catback.
