Based on the quote above, I believe I want the Flowmaster Series 50http://www.mustangmonthly.com/howto/30940/index2.html said:The Flowmaster Series 50 is the Series 40 in a pillow. The Series 50 offers a soft, throaty idle. When you rev the engine, it remains soft. No cabin noise at cruise. This muffler offers us the best of all worlds.
The Flowmaster Series 40 offers throaty idle quality with a sharp crackle when the engine is revved. Cabin resonance is unacceptable for lengthy journeys. Great sound for the occasional driver.
http://www.mustangmonthly.com/howto/30940/index3.html said:The Ravin’ sounds virtually identical to a Flowmaster Series 40 at idle. Where this muffler differs is when you punch the throttle. Punch the throttle and the Ravin’ delivers a crackly roar—a nasty bark that might actually startle the guy next to you at the traffic light. This muffler idles friendly and nicely. Where it does its best work is at part-to-full power. It roars! Not recommended for the open road where hearing is threatened; great for weekenders, though.
I like the idea of Magnaflows, but sound volume is important to me. I don't want to be the "look at me" guy in everyday driving.http://www.mustangmonthly.com/howto/30940/index4.html said:We were sure the Magnaflow would be noisy, considering its staright-through design. To our surprise, the Magnaflow delivers a soft burble at idle and a sharp, crackly roar when the throttle is opened; good for weekend cruises, but not so good for the open road.
The struggle to my personal needs is between Dynomax Super Turbo, and Flowmaster 50s. Price may determine the outcome. I do like the fact that the Flowmaster does not use sound deadening material. It relies on physics to bounce the sound and cancel waves.http://www.mustangmonthly.com/howto/30940/index5.html said:From what we could tell, there wasn’t much difference between the Walker DynoMax Super Turbo and the Ultra Flo. The Ultra Flo is a pinch louder, which wouldn’t be good for the open road. At idle, the Super Turbo offers a soft, throaty exhaust burble that won’t offend in traffic. Under acceleration, it offers us a throaty roar without the sharpness of a lot of high-performance mufflers.
Your exhaust looks custom--that's a larger pipe going from the Y down to the mufflers isn't it?Eldyfig said:I thin the model # was 17733. I cannot remember the length. It was about 3 years ago that I had them installed. I am not at home right now, so I can't get to my car's paperwork. Here is a pic of the back of my car:
Sounds good.Eldyfig said:From the Y to the mufflers used to 2". I opened it up to 2.5".
I may have noticed a little increase in MPG. Usually, an exhaust upgrade is a good way to get an increase. I can't say how much of an increase I got because it has been a while since it was stock. As a matter of fact, it was the first thing I did to the car besides an oil change.
At idle, there is a definate difference over stock; deep note but not offensive. My neighbors say they know when I start up the car. Anywhere above 2000 rpm, the note is more aggressive. So at 70, I am usually running just a hair above 2000, I think. When I gun it, people hear it coming. My buddy that works on custom trans says it sounds like a Maseratti. I haven't heard one myself, but I take it as a compliment.
I do remember before I too the stock mufflers off, those stock ones sounded like crap compared to these Dynomax's. Hope this helps.
You're right... when the speeds climb past 60 the Eldo is overcome by wind noise... hearing the exhaust over the wind noise is probably not that big of a deal.Eldyfig said:As far as road trips, you don't notice the exhaust much. It certainly isn't louder, to the ears in the car, than a moderately playing radio.
Car Talk's Click and Clack said:Dear Tom and Ray:
I am retired, age 75, and I finally splurged on a new car that I have only dreamed about up until now. I figure I only have so many years left, and since you can't take it with you...I bought a new Cadillac Eldorado with the new Northstar engine. It's a beauty, and it lives up to all the hype. I haven't as yet tried out everything they advertise about it, like the 0-60 in seven and a half seconds and the 150 mph top speed (and I probably never will), but it's a terrific car. The only think I don't like is the exhaust sound. If I were in college like my grandsons, I would think it's really cool. It sounds like the muffled hot rods that we used to drive 50 years ago that had special exhaust pipes, except it's not as loud. I notice it mainly when driving at highway speed and then especially when I accelerate at that speed. Now, don't tell me I shouldn't be driving that fast, because if I go any slower almost everyone passes me. The dealer's service department has examined the exhaust system and says there are no leaks--period. At my age, I don't need to listen to that muffled hot rod sound. Is this normal? What would cause it? And can I do anything to eliminate this bothersome sound in an otherwise wonderful car? Joe
Tom: Gee, Joe. I'm afraid it's your own fault. Cadillac makes three similar cars off of this same basic "platform" or "chassis." There's the Eldorado, the Seville STS, and the Seville SLS. And of the three, the Eldorado is the sportiest. It's marketed to swingers....people in their 50s and 60s. Not old geezers like you, Joe.
Ray: And because they're trying to sell it to younger folks, they make the ride a little stiffer, the acceleration a little faster, and the exhaust noise a little louder. They went to great pains and expense to purposely create this throaty exhaust noise because they assume anybody who wants a sporty car would want to hear the engine roar--at least to a point.
Tom: You probably should have gone for the Seville SLS (the "sport-luxury-sedan"), which is a little softer and a little quieter (by the way, STS stands for "sport touring sedan"). The SLS has the same engine as the Eldorado, similar performance, and even a set of back doors. And it's very nice car.
Ray: The only mechanical solution I can think of (other than just turning down your "Miracle Ear"), would be to see if your dealer would be willing to order an SLS exhaust system and try to install it on your Eldorado. It's risky, because taking everything apart and "customizing" it may make the noise worse, and could effect your emissions as well. On the other hand, you WILL have the only 1995 Eldorado RGE on the road (that's the Rube Goldberg Edition).
Tom: Here's my advice. Next time you buy a new car (you sound like you're gonna be around for a long time, Joe), buy an SLS. And don't worry about your losing that sporty image. You'll still be able to pick up plenty of babes in the SLS (you probably called them "chicks" in your day, Joe. But FYI, "babes" is now the politically correct term).
