Hi everyone, i noticed on the internet that some 2011 A4 has dual exhaust and some dont... Why's that?

What i mean is having exhaust on both sides and not just one.

This one compared to


vs.

this one.


Sorry if this is a stupid question, im just a newbie =)

The white car has had some mods done like the Rieger Body kit which probably included some exhaust work. It also looks like the exhaust from an S4 model.

Ty for answering my question Mikeh, how much would it possibly cost to have something like that installed on my 2011 a4? would it void any warranty?

Hey nald, welcome.
There are sooo many options for your A4. Click around the net and you'll see various segments of the exhaust. Catbacks, downpipes, etc. Range from 1500 to 6000 and yes it voids any warranty as far as exhaust goes.
If you get an engine light come on...or worse due to over airflow, workmanship etc, (due to after market exhaust) you will have to pay out of pocket. All other aspects of the car are still covered.
I'm still under warranty (except exhaust) with a full Milltek system and it's well worth any out of pocket coin. My costs were a $60 diagnostic for an engine light that worked out to be toooo much airflow for the computer to read. The exhaust works!

haha ty for your reply Blue!
I am so hyped since i know there are still so much to be done to my ride!
It's super stock right now (except for the s-line upgrades).
Im planning on tinting it next any suggestions on what % looks best on a black ride? I live in calgary alberta so if anyone knows any good tinting places please hooke me up!

To answer the op question here is a breakdown of what is what.

-The V6 A4 sedan came with a dual exhaust (single tip on each side) as does the A4 Avant 2.0 TFSI.

-The 2.0 TFSI sedan comes with a single exhaust (dual tips).

-The S4 comes with a quad setup (dual tips on each side).

If you decide to go with a dual setup you will need the following:

1 - 8K0 804 172 - Passenger Side Heat Shield
4 x N 907 965 02 - Clips for Heat Shield
1 - 8K0 253 144 M -Hanger Assembly
* And of course a new rear valance and exhaust system.

As others have posted many aftermarket systems out there. If you go with single tips the A4 Avant or V6 A4 valance would work or for the quad setup the S4 valance is the way to go for an oem look.

BTW if looks is the sole reason for the swap, you could/should look into a used Avant oem exhaust that someone has upgraded to after market unit (such as myself). This would bolt right up and offer the best bang for the buck.

Hope this helps!
