Re: [Amc-list] scavenging in a stock exhaust system?

[Wrambler242@xxxxxxxxxxx]

Dynomax uses a perforated pipe laid across the muffler body at an angle surrounded by loose roving packing, er, fiberglass.  I have used them on a couple of Jeeps and one is destined for my WJ at some point.  They have a nice sound IMHO. If anything they start out being slightly too quiet, then mellow up a few decibals as the packing settles and burns in. 
   I've no regrets to using a Dynomax, Note, you can order them from Rockauto from the parts number and I've sent out a 5% discount code I can resend if you need it.  Dynomax also has welded and stainless versions for those with less RM.
