I have a 2002 Eldorado ETC Collector Series this car was suppose to have a stainless exhaust, but the mufflers are rusting. I'm looking to replace the system from the cat back. any comments or suggestions.

have a friend that can weld.

We did the cat on an '02 DHS, and it was pretty straightforward. We dropped everything from the cat back, he made a couple of welds, and a bit of wrench work.

Maybe a couple of supports to hold it up as you reattach.

You're in the exhaust shop custom stainless steel welding business. Be careful which mufflers/resonator you use or you''ll create a drone that will drive you crazy at highway speeds.

The original exhaust system was stainless steel. Here's part of my 2002 original. (Replaced with a CORSA cat-back in 2006)

Thanks for the reply, did the CORSA's change the sound? I can't believe the shape of this system with only 48k miles

Yes, the CORSA very definitely "changed the sound" for the better. Their catbacks are not made for Deville or Eldorado - or for several earlier Seville model years.

The Corsa has a decent rumble at idle, is very docile around town, has no drone at highway speeds and, when you put your foot in it, it will wake the dead. There's not a baffle in it - it's all straight pipe with tuning cutouts in the resonator and muffler cases. You can see right through the entire system.

Here's the resonator - see the rug ?

You want the least restriction you can achieve - in whatever mufflers you use. And the exhaust and Y-pipes are pretty lousy in the original setup, too (Post #3).

That looks really good. I'm going to make some inquiries around town and see what we come up with. The weather is getting better, time to remove the cover.

I've heard the collector's edition models have a slightly different exhaust from the factory to sound a little throatier than other standard models.

Curious to what your factory system sounds like.. I've been looking for something just a hair louder than my stock ETC setup.

Can't swear to it, but I think they all got the same exhaust systems.

The 2002 ETC ECS has an exhaust all its own. Although, it doesn't sound much different then my DTS. Now Sub409 went out to make a difference, his Corsas look awesome.

that last surge off "collectible" eldorados had their exhaust tuned to sound as close to a '53 as possible.

I think that's what I was getting at.

Wondering how exactly they're different. Maybe just different mufflers?
