A4 2.5 TDI V6 180, De-cat?

[A4cab-Izzy]

Hi guys,

in need of some help here, i have been hearing many different opinions from people on this so see what your guys input is.
I am thinking of a exhaust system for my audi a4.... I was thinking to de-cat it, with a full through 2.5" pipe without back boxes aswell?

People have been telling me this will affect back pressure, and being a diesel i will loose torque? So i need some input before i proceed with anything.

Thanks look forward to hearing from you guys

Thats a load of rubbish ! If yours is the 180Bhp, then i will start by loosing the pre-cat (evil contraption) then i will move onto the main cats . Take them off and hit the innards with a long metal rod/copper pipe and get rid of the monolith inside. The noise wont increase and the turbo will spool quicker. It will also pass the Mot test as well...
