Hemi mufflers

[slyfox]

Hi, I got Hemi mufflers on my 400 Cordoba 4bbl, no H pipe,  I'm pretty sure one of my mufflers as a baffle rattling, would this cause it to idel rough. Thanks.

Are you getting approximately the same exhaust flow from each tailpipe? Check when engine is warmed up(heat riser open position). If restricted flow through 1 muffler, you could be getting a slight difference in back pressure which could cause the rough idle.

I'll check it tonight. Thanks

Hi, I did what you said, Pressure seems the same, but one of them sounds like a tin can when idling, When I rev it up and let go quick, there's a something in the drivers side rattling bad. I'm guessing that's my problem.  Be the last time I buy Hemi  mufflers from Accurate Exhaust, only 2 year old.
