It's amazing how much smoother this sounds compared to the sound clip with an H-pipe exhaust in one of the replies to the original post.

Damn, that sounds sweet. What diameter pipes are you using? Can you feel any difference in the acceleration, drivability?

OE is 2-1/4. The car belongs to Swen_S8 from the Netherlands.

This is the <A HREF="https://forums.audiworld.com/a8/msgs/56520.phtml">Original Post</a> (note the lack of cats and any crossover), then he installed the cats and H-pipe, and finally he replaced the H-pipe with an X-pipe in this <A HREF="https://forums.audiworld.com/a8/msgs/75063.phtml">Final Post</a>. In this last post he comments that performance "definitely improved in the higher revs" from the X-pipe change alone, and he reports a 292 g/sec MAF reading.
