Yes, it can be made to suit your requirements.. (flow, sound, etc)... In my exhaust, everything was custom made including the mufflers.. With anything "off shelf" they generally try and find at happy medium for their potential customers.. Also, because they are bulk made this is where quality and fitting issues can be a problem.. IMO Not saying custom made is the only way to go, however I like being able to have input in what I am buying and dealing with a professional that backs up his work 100%.
