   group N is a rally spec, there is group n and group A. Basically means its a god damn loud exhuast as all they care about it power not noise limits etc for MOT's. Hope this helps.

   just a very unrestrictive exhaust, allows the gases to flow out better.

   yer, all they want it the maximum power form the exhuast because emissiosn and noise dont matter. group A is a lower rally class, group N is like the WRC cars i think.

   it means it complies with regulations to exhaust systems for that race/rally series.
   noise does matter, limit for group N is 98db.
   
   and its is far from WRC.

   you would need to read the regs for that group/series to see what the exhausts have to comply with.

   Yeah Group N is just another class for rallying. More road based cars.
   
   I could go into detail but there are things like you cannot adjust the suspension geometry and you have to keep a certain amount of trim in your car.
