These exhaust pipes are made by  Armours in the UK.
Our stainless steel pipes are made from Grade 304 stainless steel. The advantage of stainless steel is that it will not rot even when neglected. Some yellowing and discoloration  may occur depending on how hot the pipe gets, periodic polishing will restore the product back to as new appearance.
