hello guys. i just got a 1965 deville and i must replace the exhaust. it's broken and rusted. what is the best pipe size for this cadi. it has 429 ci. more power and sound needed. and if you know any place sell parts for this car, headers, lowering kit, and body parts.
I used to own a 64 deville with the 429. Mine was kept stock so im not sure about performance parts. But if you need parts, I used to use www.caddydaddy.com. They are a bit pricey on some things, but they usually have hard to find parts.
Automobile(s): 75 coupe de ville , 76 sedan de ville.
Re: 429 Engine
I just replaced the exhaust on my 65 coupe de ville, did it myself, it had single exhaust . I cut the pipes just after the manifolds on both sides got some 2" pipe and a couple of cherry bombs, exited the pipes just after the doors on both sides, and presto ! cool dual exhaust, sounds great , looks great , performs great, if your inclined and have acess too a set of torches..
I ran 2 1/2 inch duals on mine back when I built the engine on the old 65. If youre going to get into modding this motor, know that it costs a friggin fortune to have custom parts made. Most obvious mod setup is a 650 carb with dual exhuast and a K&N. If you want more, it gets a little nuts.
