I am so impressed that my decatted 93 wrx has gone straight through the MOT test (for the 2nd time since I have owned the car) I just had to post about it!

For a 15 year old car this really is testament to Subaru's build quality.

No problems with the emissions test, tested as non-catalyst equipped, 1.35% actual CO against a maximum of 3.5%.

 

its good when that happens init .........well done

 

Hi mate. I was toying with the idea of a full decat system on my 1993 WRX too (just need downpipe - got the rest of the system), but wasn't sure if it'd get through on emissions. You've given me renewed hope (must replace my knackered Lambda sensor first though ). Cheers for the helpful post .
