I'm looking to loose one of the Cats in my MY98 UK Turbo, however I don't want to risk an emissions failure.

Which is the best option, Downpipe or Midsection?

Also, any comments on which make to go for? I currently have a Scoobysport backbox, so am tempted to go Scoobysport. I have noticed that Power Engineerings downpipe has a seperate pipe for the wastegate? Is that a better design, or does it not make much difference? Which provides the better sound / power?

Thanks in advance,

James.

 

Losing the centre cat will not affect emissions and will give a small increase in performance.
