View Full Version : Repack Kit?

07-18-2010, 01:20 AM
Which repack kit do I need for my muffler (model# 425-17560)? Is there a pillow pack that will fit? I am at the fewest recommended number of discs and still wake up the neighbors.

I apologize for being redundant as I posted this thread in the Tuning/Performance thread as well.

REPACK KIT 4": FIBERGLASS 10"X.4LBS STI. This kit contains four tenths of a pound of white fiberglass mat. This mat is used in our 4" external disc race systems and 4" megaphone systems. One kit is enough to repack one muffler.
