With the cone facing the end of the pipe, i have a deeper rumble and it is loud. Up here in northern wisconsin, deer are around every corner, so loud pipes really do save lives. If your on the fence about theses inserts, do it. D&K has a great product here.

Thanks Kevin, I already watched the video, but it doesn't show any actual installation of the TTI's, hence the question. But if a basic cordless drill can get through, then I think I got it from there. Will be ordering some very soon.

Thanks for the tip Mac10
