Hi All

need someone to confirm whether i can do a dual exit on my Audi A4 B9 2.0 tdi.

i wanted to facelift it with the dual exit on the newer shape and i have the parts but i ran into a problem.

the oval tips doesnt fit on the opposite side as there is a black box , anyone know what this is ?

how do people get round it ?

Going to take a guess and suggest the black box is the control ECU for the TDI aftertreatment system.

thanks for confirming , make sense as the ad blue is also directly above it.

Ive got a diffuser and the chrome
Strip waiting for someone who has a dual exit already or a TFSI LOL

I've seen a lot of people do a fake 2nd exhaust because of the adblue tank and other obstacles... Planing of doing the same with either a B9.5 rear or a B9 normal twin bumper.

But you would have to get the same exhaust as the other side.

any guidance on it at all ?

I'll probably buy a new exhaust tip for the original too, i've seen some cool ones, like chrome or black..
