This is a set of resin 1/48 P-51B/C Mustang exhausts from Ultracast. These exhausts replace the Tamiya kit #61042, #61047 exhausts to give a higher level of detail to your model.
Each exhaust pipe is hollow on the end for added realism. These resin exhausts would be a big improvement over the plastic kit exhausts.
You can buy this and many other detail items directly from Ultracast.
