Ibrar Jabbar Posted January 8, 2004 Share Posted January 8, 2004 If you are buying a cat back system it will bolt straight on. Quote Link to comment Share on other sites More sharing options...
Scooter Posted January 8, 2004 Share Posted January 8, 2004 "Edited re Ibrah's later comment, the Uk sensor is mounted on the 2nd Cat pipe and so the sensor issue is only relevant when decatting" FYI your UK does have a sensor mounted in the 2nd Cat However it seems to be common practice see here to just tie the sensor up out of the way and not refit, but as this was frowned upon by some with more knowledge than I maybe a current uk'er can comment. Bobbeh, Geeza.....Branners? Quote Link to comment Share on other sites More sharing options...
Ray Posted January 8, 2004 Author Share Posted January 8, 2004 hmmm well its something il have to think about then Im most certainley going to remove the cats.

Ibrar Jabbar Posted January 8, 2004 Share Posted January 8, 2004 Originally posted by Scooter FYI your UK does have a sensor after the 2nd Cat thats mounted in the standard exhaust and the apexi almost certainly won't have any such mounting. However it seems to be common practice see here to just tie the sensor up out of the way and not refit, but as this was frowned upon by some with more knowledge than I maybe a current uk'er can comment. Bobbeh, Geeza.....Branners? There isn't any sensor mounted in the exhaust itself, so an aftermarket exhaust will bolt straight on to the second cat pipe.

Scooter Posted January 8, 2004 Share Posted January 8, 2004 I'm almost certain Geezabloke and Bobbeh are running without the sensor but i didn't want to just say go right ahead........ the decatting thing is another FAQ but basically the Uk cars don't respond as well as the j-specs with just a decat & exhaust (something to do with the different wastegates).

Terminator Posted January 8, 2004 Share Posted January 8, 2004 The UK EGR system defeats alot of the gain with decat, you need to add a boost controller. Or get a lighter faster JDM car.:flame Dev Quote Link to comment Share on other sites More sharing options...

I would argue they respond better. The UK specs boost to about 15 psi unlike the j-spec that tend to boost to silly levels. Quote Link to comment Share on other sites More sharing options...

Terminator Posted January 8, 2004 Share Posted January 8, 2004 What is your max boost without a controller Gavin? Quote Link to comment Share on other sites More sharing options...
