Does the 1.8T and 2.8 have the same rear muffler exhaust hanger layout. Im looking to get a stock muffler put back on my car and i want to know if a 1.8T muffler will have the same mounts.

Thanks

I would think so I have an s4 muffler on my 1.8

Just looked at ETKA. All the mounts are identical. The differences are forward of the resonator. Interestingly, there are 4 different part numbers for the quattro rear muffler itself and the splits are funky:

1.8T pre-facelift
1.8T facelift

V6 drive-by-cable
V6 drive-by-wire

I would guess they are just "tuned" a bit differently for the different engines.

Identical even for quattro? Hm..the different part numbers
Must be for the different pipe sizes. What is this database u checked?

I only checked the mount situation for quattro cars. Obviously the Frontrak stuff is completely different from the quattro layout.

There is a pipe size difference, but it is a little less than clear. I'll identify the clamp size that is given for each:

1.8T pre-facelift: 55mm
1.8T facelift: 60mm

V6 drive-by-cable: 60mm
V6 drive-by-wire: 60mm

However, the V6 drive-by-cable muffler has a remark stating '50mm', which seems to be at odds with the required clamp which is 60mm. But that remark is only there for 98.5 and 99.0, even though the part number is listed for other years where no remark is given. The remark is probably in error. Data is from ETKA.

I've found ETKA is next to useless for exhaust information, even if you manage to decipher all the alternatives it'll most likely end up being wrong anyway.

I just called a dealership and he looked up on the computer the difference between the 1.8T and 2.8 exhaust size. He said that the..

1.8T = 55mm
2.8 = 60mm

so i guess it is usless to get a 1.8T muffer for my car because it is not as efficient. does anyone have any input about weather 5mm is worth not picking up this muffer? dam.


edit.... something has to be wrong with this....
60mm = 2.3622 inches
55mm = 2.16535 inches

so the 2.8's stock exhaust is reall 2.36inches? and people call going form stock to a 2.25inch exhaust an upgrade? im confused as hell now. maby the '60mm' or '55mm' is OD or ID?

That is the clamping diameter, so OD of the pipe.

i wonder if 'clamp diameter' or OD is the base for which people ushally measure pipe.
