The reason I asked is that you paid $2.5K for a "custom" stainless steel exhaust and you ended up with what looks like an Xforce mild steel dump with off the shelf mufflers? I'm a big fan of custom exhausts, I even paid a little more than you for my old 3.5inch system. However, the whole exhaust was custom made, including Dump and mufflers.. Not off the shelf products that have pieced together. At the end of the day, as long as you are happy with it that's all that matters. However, if you going to post details of your mods on a public forum, expect to get honest opinions and feed back. Ben
