Cadillac quiet performance exhaust?
Is there such a thing? I have a 64 LeMans that I'm putting a mild 400 in. I am using 2.25'' Ram Air Restoration manifolds and plan on using 2.5'' mandrel bent tubing for exhaust any thoughts on mufflers? I installed a layer of Dynamat style sound deadener and a layer of thermal barrier over the interior also new carpet. H pipe X pipe no crossover any info is greatly appreciated.
