Need help with changing exhaust on a Newage
 

I uploaded this pic to make it easier for me to understand the various exhaust system components and which bits can be changed to stay MOT friendly on my 2005 WRX that has the Prodrive Performance Pack.

Im told as part of the PPP, the 3rd cat on the mid pipe has been changed for a decat pipe, is this correct?

Could a decat UP PIPE be installed with a Sports Cat DOWN PIPE and still be MOT friendly with the 3rd cat removed?

Ive currenrtly got a Blitz Nur Spec S Back Box installed.

Anyone give me any advice or anyone post up specs of their exhaust systems.

Many thanks in advance.

aslong as you have the cat/sports cat in the down pipe you should pass the MOT. therefor removing the up pipe cat shouldnt affect it.

you may well require another remap if you do decat the up pipe though

I only have ppp sport cat in downpipe and after speaking to mot tester he assures me all should be fine, MOT due in about a month so will find out soon

I have the TSL thundercat Downpipe with the Sports CAT and straight through Center, just had my MOT...... Had problems with the CO2 levels to start off with but after a quick blast around the block to get the cat nice and hot all was well and she sailed the test.
