Good morning,
I'm not to keen to hack the OEM system apart for the mod as I may go back to standard in the future so keen to see if anyone has some back boxes for sale to release some noise? Ta,
 
I have a set. Come off my 37000 miler. They won't be going back on. £300 seems to be the going rate. Located in Wiltshire
 
Thanks for the response, are yours oem with a mod and if yes what have you done to them? I ask because having listened to some that have been modded too extremely they sound a bit over the top imo..
Or are they aftermarket if so what manufacturer? Thanks again..
