Back Pressure - Zorst ’n’ filter

[Karl]

A Peugeot engineer guy that lives near us reckons if you change your exhaust and put an air filter on a VTR you ruin your back pressure and your car will be slower than before the mods.
This true?
or is he talking out of his arse? :S

Depends which filter and Exhaust

If you get a CDA and a Magnex system you will be fine

We can sort something if your looking to buy smileys/happy.gif

standard vtr manifold is very restrictive, citroen designed in this way to make the vts so much better.
