#2254 of 3244 My 1997 Crown Victoria by henry_c May 15, 2004 (3:48 pm)
Question. I have Four Catalytic converters on my Vic and I am wondering are they Really necessary to have Four of them? Can I have two taken off and still pass smog. I know it will change my horsepower and my fuel consumption. But how much would it change the horsepower and fuel consumption. My Vic runs great. but that model year only came with 190 hp on the 4.6 . I have a K&N air filter on it and am planning on having the exhaust system changed next month to dual exhaust. Suggestions on the Catalytic converter issue and would it be better to have dual exhaust Or a single exhaust with a three chamber muffler and two inch tip? Oh, and the car has 100,600 miles on her. Well maintained.   Henry Replies to this message: hotrodlincoln1 (May 20, 2004 12:23 pm) henry_c (Jun 04, 2004 4:36 pm)

Replying to: henry_c (May 15, 2004 3:48 pm) I'm not sure, but I think you have to keep all the cats in order to comply with federal regulations. It would be best to ask your local authorities what they will accept, since enforcement varies widely. If you think your cats are bad, you can have them replaced. High-flow replacement cats are available, but they aren't cheap.   You can get performance out of a dual exhaust or a single, but if you keep the single, it needs to be much bigger than 2". If I wanted to go that route, I would get at least a 3". Your best bet would probably be a dual system with a crossover (H or X) pipe. Choice of muffler depends on your noise preferences. I prefer straight pipes or glasspacks myself. Replies to this message: henry_c (Jun 04, 2004 4:36 pm)
#2256 of 3244 2001 Grand Marquis by whitpg22 May 27, 2004 (11:58 am)
With approximately 47,000 miles on my car, my overdrive went out, subsequently requiring me to replace my transmission. The dealer stated that what occurred was something they don't often see. I don't have much technical knowledge, but was curious if any others had experienced problems so early? Thanks.
#2257 of 3244 Overdrive by jsylvester May 27, 2004 (8:23 pm)
Myself, I've never heard of one going out before. I've heard of torque converter issues from bad fluid, but even then that is fixed by merely replacing the fluid. Replies to this message: e_gillman (May 28, 2004 7:16 am)

Replying to: jsylvester (May 27, 2004 8:23 pm) I've been told that the transmission fluid should be changed every 25-30K miles on our cars. Especially if you drive alot of short distance driving or heavy traffic. I change mine every 30K miles and have no problems so far at 72K miles. Is it possible the fluid was never changed and that this may have caused the problems?
#2259 of 3244 Buying 04 GM LS by carbuyer2 May 31, 2004 (7:16 am)
looking to buy an 04 GM LS - trying to decide new vs used with 10,000 miles - can anyone provide some recent prices they've paid for either - is it worth buying slightly used given rebates - Thanks

I honestly think Mercury should freshen-up the Grand Marquis. Even though the majority of the sales are to cab companies and police fleets, they should just add some new things. New attractive styling, newer features, and other updated things that may draw buyers to it. While almost all of the Mercurys in the Mercury line-up have key-Mercury styling details, the Grand Marquis doesn't. I think Mercury should just think about even adding little things that would make it better.

The Crown Vic has many of its sales to fleets. That is NOT true of the Grand Marquis.   There is even speculation that some day the Crown Vic will ONLY be available to fleets, but so far the Ford dealers have raised so much you know what that that has not happened.   And if the cars are/were selling without substantial investments, Ford didn't/wasn't going to do much to them.   The Chrsyler 300C and Dodge Magnum (and coming Charger) may change all that. Or not.
#2262 of 3244 2006 Refreshing by jsylvester Jun 01, 2004 (9:23 pm)
Cars are to be refreshed for 2006. What that means is unclear, but expect no huge changes.   Some talk that the new 3 valve cylinder head 4.6 engine in the 05 Mustang will make it, and a lot of hope that the interior will be updated. I would not expect any big exterior changes, as the styling has worn well for it's purpose.   As mentioned, if the 300 steals sales, expect to see more changes.

Replying to: hotrodlincoln1 (May 20, 2004 12:23 pm) Thanks for the tip. I tlaked to Ford afew times about the CAT issue and they all said the cats have to be there. As for the axhaust system, I believe I will go dual. Not sure how the muffler shop will do it. I have not talked with my muffler guy in awhile. I did think about a three inch system on my Vic, but that would look kinda funny, though the result may be awesome...I will run that by my muffler guy to see if a three incher will fit around the rear axle, etc.
