Vtx chopper exhaust

I was wondering if there are any companys that make a short LOUD style chopper exhaust for an 06 XTV 1300? I also have the capability to bend the tubing and make the exhuast myself then i would just have to have it chromed but i didnt know if having a straight exhaust is a bad thing. I am not to familer with back pressure and all the terms i guess you would say but if anyone could possible help me out a little it would be greatly appreciated.
