Due to the size of aircraft the DL-20 is going to be put in we are offering two different versions of our Wrap Around Pitts Mufflers. As with all of our muffler we will also modify or build to customer specifications.
We offer a Standard size version which uses a 1.5" diameter can and will generally work with airplanes that has the DL-20 carburetor mounted in front of the firewall.
We are also offering a Compact Version of the Wrap around Pitts Muffler which uses a 1.25" diamter can and is designed to work with airplanes that have the DL-20 carburetor mounted inside the firewall.
This does not mean the standard or compact version is guaranteed to work with every airplane and we strongly suggest measuring the amount of room you have behind the cylinder before purchasing your muffler to determine which muffler will fit. Remember many of the airplanes that this engine is being put in were not originally designed for this style engine.
All of our mufflers are built to order and as per our company policies we will not accept any returns of mufflers that were incorrectly ordered.
If you have any questions or doubts about fitment you can email at firstname.lastname@example.org or call us a 704-799-1658.
