HMM i did try and make the link work, but cant see the zorst in question. anyways it should be ok
the exhaust needs some pressure in it as i understand it, but generally the faster the exhaust gases escape the better*
i just have a manifold, cat, centre section from a vectra then no back box, mine works nicely, sounds good as well

*feel free to correct me if ive got this wrong*

Imagine all the people who have twin zausts. If they didn\'t work then no one would do it.

Try and get a system that splits into two silencers rather than running a remote pipe from the rear of the main silencer over to the second.

While you\'re having exhaust work done, get them to fit an extra silencer in place of any cat section - there\'s nothing worse than having a constantly booming exhaust note!

[quote=\"Q-C\"]I would keep the cat. gains will be minimal and you\'ll get worse mpg, louder exhaust and higher emissions[/quote]

Cat is an expensive component to replace so fit a silenced decat. Noise levels are reduced and emissions are typically below the limit anyway on baby Vauxhall engines.
