hi guys
i'm looking for a blitz backbox only exhaust,can anyone tell me the difference between the nur spec r and nur spec s?? also at the mo i have a prodrive exhaust on as part of a ppp will it be ok to change to a blitz or will i have any problems??i have a 98 impreza wagon turbo!

thanks in advance for any replies

nick.

 

the nur spec r is the system and the s is the backbox.

 

as above.Plus the s has 3" pipework that tapers down to fit the standard centre section whereas the R is 3" all the way
