200cell cats plus Xpipe =loud and rasp. How to fix the sound
#22
A pair of 18 cherry bombs definitely helped some
Placement is right downstream from the xpipe.
After driving for a few days , I must say it sounds nearly perfect with fuse 19 back in. Nice deep rumble at slight rpm increase yet no drone. At idle it's quiet. At full throttle it's throatty but not overbearing. Happy with the outcome!
