NOTE: I currently dont have these installed (I am hoping sometime later in the year or next year). I was just wondering if it was possible to get a cert for the exhaust because its going to be quite loud (over 90 dB).
I still want my car to be road legal (bearly;) )
I am quite new to the car scene so any help is appreciated
You'd need to find a vehicle owner who has fitted that exact combination to get an answer on if it could pass or not. We would not know until we tested it, as we do not keep easily accessible records of exactly which components each vehicle uses. My suggestion would be to fit it and if need be add a resonator into the middle of the straight pipe.
