...so people have to make there cars quieter to use test tracks..i noted Porkie said it aint hard to quieten a car...very true BUT after looking at Martin H's masterpiece of an exhaust surely this has a dramatic effect on BHP?.....Isnt it better to just run less boost (i asume its less noisey)..Are we gonna see cars that dyno at 700bhp on the dyno(in which the big playas all harp on about) in reality be 600bhp due to bigger exhaust restrictions?


Or am i wrong as per usual.
