Does anyone have the sidepipe inserts, (maybe an FE) and if so can you compare them to a typical, smaller flow thru diameter, glasspack design. I had these mufflers on an LS1SS and they sounded great.
Scroll down to see the sidepipe inserts. Also there is a sound clip in the Sight and Sounds tab on the left side of the web page.
