Made up a 3" 1st and 2nd stainless decat pipe, fitted them the other day with a HKS super dragger back box, looks the nuts but was to quiet could just about hear it over the dump valve and turbo spool.
So out come the grinder today cut the end off the back box and removed all the wadding, never seen it before but its cladded with, what I would say is drilling swarf then packed out with a cloth wadding. I have removed the lot so its just the skin of the back box, tig welded the end can back on, put it back on the car and run her up. Its a little louder on tick over but more throaty when it rises above 1.5k so Im a happy bunny for now:eyebrows: Going to look into changing the pipe that HKS supply as its made from the crapest steel going with some nice stainless as it should be, have a play around with rear box's to see if I can change the note and end up with a unique look aswell
will try post up a sound clip or vid soon
