What has been done by others to a 472"? We just bought a '71 Coupe in mint condition. Also, what can we do to make the exhaust rumble? We do not want to ruin it, just redo the E

A set of 3 chamber Flowmasters will give you a nice rumble sound with out blowing out the neighbors windows.Cant remember who it is that specializes on Caddys but Im sure some on else here knows. Just my 2 cents but that paint needs to go. Maybe Black with a nose to tail flame job, yea thats the ticket.

The Flowmaster site does not even list Cadillac in the application guide.

Just go down to yer local Speed Shop and get a pair to fit yer pipe size or go to the muffler shop and tell them what ya want to do and they can fix ya right up. Piece of cake.

Hi Alan, Nice Ride. You don't have to do to much to a big block Caddy, To make it GO or to make it sound good. A pair of turbo mufflers at your local exhaust place will do the job. I work on a good amount of Big Caddy Engines,Mostly in older Chevys & fords. For Infomation or speed equipment, go to Maximum Torque Specialties (Cadilliac). They sell big block Cadilliac Hot Rod Stuff (472 - 500 c.i.d.)
