Hi guys and gals ..... I have a 2015/16 Dog with an S&S V111 which I believe you'll call a chopper. 250 rear end and a 10" over front end. I have the stock Supertrapp 2 into 1 4" mega exhaust system fitted. I'm just guessing from the Supertrapp website that it could be part number 828-71471. The Supermeg system for custom 250 rear end softails. I'm looking to add a few plates and replace the open end plate as it has a small crease in it. I wondered if we have other members who have already played around with this system ..... baring in mind it's a pretty new 250 BDM chopper which has been put together for us guys in Europe (UK). It's not the TUV motor .... the Supertrapp has a small opening end cap. Cheers in advance to any responses from guys with the same set up ......... Oh and wishing all of you guys and gals a belated Thanksgiving. I hope you all enjoyed yourselves and spent good times with the people you love. Malcdude.
