Got a Piper full system with middle box fitted to my VTS. Sounds lovely, but I rekon it's a little on the loud side though. 
Been thinking and I may look into having a box welded into the decat pipe (providing there's enough length to work with - it's the shorter MK1 pipe) to keep the noise down a little.
Will there be any noticeable loss of performance/ throttle response by adding another box to the system?
Cheers
