Only with a grinder... 
Well could always run it without the back box , not that loud is it
Anyway who do i order the exhaust from please ? 
Funny you should say that, last Exhaust I had fitted on my MFL V6 was at the VX Stealers (2 middle and rear box). I promptly went to collect when I was informed was ready ! On walking across car park I saw my car and noticed the Tail Pipe on them "New VX Exhausts" must be short as I could not see it

On closer inspection I looked under the rear of my car to be greeted my two shiney middle section pipes looking at yer !

and NO rear box

Surely it would have been a bit "Throaty" when parking her !!!
I walked in and asked the service lady to "Come outside"

A suggested she look look under the rear of my car ( in the "very" short skirt aka Belt - not as I had noticed or the reason for making her look under the car

) and tell me what perhaps the issue may be !!!!! Ooooh Sir was the reply !!!!!! I had to wait another day as they did not have one in stock.
