Hi all,

I would really appreciate any help, i have a 1996 sti import saloon, i have just had it for an mot and it failed on the exhaust emmisions CO levels, it still has the original air box and filter and the original downpipe and cat fitted and a s/steel from the cat back, could anyone tell me any possible things i can do to get it through the retest.

Thanks
Dan.

 

Make sure they tested it against the right levels.
