I would think they would be fairly similar between the two unless their resonators are very small or something.


The Mpe tends to be the culprit on on the s55. Is your mid also resonated?

A resonated mid might help but again mpe's are very tough since they were designed to have factory cats and resonators in place. The material they are made from also has more of a tinny sounds as well.

Can anyone purchased this downpipe confirm the accessories you got?
I only got 3 sets of bolt and nut besides the downpipe itself.
