Selling a Da50 with header and canister. All items were purchased around march and have about 15 flights on them. They were installed in my ars 300 and I am selling as I just want more power. The canister has developed a dent around the mounting area. It doesn't affect performance but non the less it is there. I will also provide a standard muffler with the setup as well. Asking price is $550 shipped due to the dent in the can. You can respond on this ad or message me at+12053565828.
