Red5speed Posted October 29, 2005 Report Posted October 29, 2005 I was wondering what the stock size and specs are for the mufflers on my 1992 Lumina Z34? Also I have a wierd rattle noise coming from the exhaust system (I'm guessing from the converter), is that common? I'm looking at Flowmaster 40 series for the mufflers, and I'm not sure what to do about the cat. Any thoughts about Flowmasters on my car? I'm looking for a low growl, very little "rasp", average noise outside, minimal noise inside, and good power. Basically the best of all worlds... yet I don't want the import sound. Any other mufflers to look at? Thanks for the help. Quote

Flowmaster's (and especially 40's) sound like complete and utter ass on 3.4's, and personally I suggest Magnaflows (as would many other people on this board). Flowmasters are simply FAR FAR FAR too raspy for this engine. Quote
