i jus got defected in brighton n they sent me 2 a blue slip station and epa.. i copped bout 12 defects n the only thing the blue slip station will look at is the defects on ur blue paper.. they will also take photos on th vehicle as u bring it in so u cant change it all back..The front mount they will not clear.. they will send u 2 epa, engineered or not u r gonna get done for the front mount n have to go to emissions, there is no way out of it unless u put ur standard one back on.. I have spent jus under 3000 on fixing my car 2 standard n still havent finished.. Another thin they done me for is my at, coz its an older car ur cat is most likey not gonna pass emissions, so if u wanna leave ur front n mount on, im guessin ur gonna need a new cat!! if u get ur front mo0unt engineered by the way, if a cop pulls u over he can still send u 2 emissions with an engineered front mount n even if u have a certficate to say that u passed emissions they can still send u back, coz there is no photo evidence of the front mount at emissons.. I have jus been through it all n still going through it, n i feel sorry 4 u!!
