I posted pure (stock non Comp),( Comp ) plus Just posted (X Pipe only). All three vids are the same iPhone so you can compare the differences. All three vids have the stock rear muffler. Just resonator changes.

thanks for the link, xpipe alone and nothing else sounds decent. if you ever end up doing a video with the car driving under full load, please post.
