Re: [Cadillac_Performance_Association] 1970 DeVille header and exhaust question
- i think flash has headers that will go right on the car no cutting needed.----- Original Message -----From: Scott PearsonSent: Tuesday, April 22, 2003 9:08 PMSubject: Re: [Cadillac_Performance_Association] 1970 DeVille header and exhaust questionSo you're saying you want headers and duals? Yes, this will increase power.
I heard somewhere that some year of Chevelle BBC headers will work with the
full size Caddy. You will, of course, have to cut the flange off and weld a
Cadillac flange on them. I think MTS has them.
I've never heard of an off the shelf dual exhaust system for these cars,
since yours is pre-emissions, just find a muffler shop that bends pipe.

Another poster mentioned a company called 'flash'. Is there a phone
number or a website? I checked MTS (http://www.500cid.com/) but I
don't know yet whether they fit. I found one person who said that
these headers will give you only around 10hp.
- The cross member that supports the transmission has a
bend on the driver side so the exhaust pipe can pass
by.What my muffer guy did was remove the cross member
and cut out a part of the pass side and welded a cross
section of 6 inch channel steel.So now it has room for
a exhaust pipe on the pass side.I left off the
resonators because the stock ones are pretty big and
like i said it would not fit on the pass side because
the gas tank is not centered in the car.I wish i had
them.There are smaller ones and i would use them.I
think i get 2 mpg better.Before the car went around
105 mph ,now it hits 115 mph on the same road.Its
running cooler i think.So its worth doing.I,d get some
walker muffers or marymount muffers if i had to do it
again.I,ll try to send a pic.Good luck cadillac
