ok so im getting an andy f remap in the next couple of weeks and i am fitting a hayward and scott 2.5 bore sports cat to my wrx and was wondering how many people on here have had them fitted and successfully passed mot?

I wouldn't worry, emissions rules could be completely different by 2010 !

If you are at all concerned just get it mapped with the standard DP and rear-decat as you can get very good power from a remap and this alone.

Mine passed with just that cat on it...wouldnt worry. If you are slightly worried then just make sure you get the car nice and hot before taking it in for the MOT.

Have a H&S high flow down pipe which retains
one of the two cats. The existing cat is a sports cat
I think. I also have the H&S de-resonated centre section
with an STI silencer. Mine scraped past emissions while being
mildly warm. So don't worry, I've just kept the resonated
section and take it the test station in case there happens
to be problems during the mot.

This is my set up on the Stealth Wagon.

Hayward & Scott 100 cell high flow down pipe (only 2 BHP loss over decat pipe & MOT friendly)


H&S up pipe


H&S Centre pipe straight through


The short section & Backbox from the PPP.


Coming up to it's 3rd MOT in March & passed the first two without problem.
