Hi, i've got a triangle shaped exhaust with 2 outlets, one larger than the other. Have been told it's a blue flame- I need a baffle for the smaller outlet, got the larger one and fitted it but it doesn't seem to make any difference in the noise!
the baffle's are held by large circlips if that makes it easier to identify. only really need it for the mot or will it pass with only 1? Anyone any idea's? Tried the blue flame website but they don't list the twin baffle type
Cheers BriF
