Do the cars pass the emissions with the cat built in on the motorbike exhaust then ? I have a 1996 mx5 donor, so my car would require a cat, but the systems suitable on a. 7 is basically a straight through, so I just wasn't sure if a bike can is used, how iva & mot friendly the bike cans are ? I know that they will definitely be louder, but will they fail the tests ?
