Getting FlowMaster Super 44's tomorrow.. What tips!?
1 - 20 of 28 Posts
I was thinking about going with Delta flows on mine as both of my stock mufflers now have holes in them.
I didn't think the stainless steel would rust. Bummer.
I didn't either, but I have to work hard to keep it off my SS tips, too. I guess its just another sign of the times - inferior products/processes.
Corsa exhaust man... Corsa. Or Borla. Flowmaster is good for some cars. But my opinion is that Corsa dB mufflers are the right ones for our cars.
I don't know, I think I'd have to add the dual slant Corsa tips to that list.

+1 on the 02-03 STS tips, the tips on mine are some of the best looking tips I've found and the only way I'll ever consider replacing them is when I someday put Corsa on the car.
Not to get off topic...
Hey, Iowaseville, about what part of Iowa are you located, if you don't mind me asking? I'm from around DSM myself.
Back on topic...
Realizing now that you were asking another question, I will also concur with Gizmo on this one- keep the stock tips. They look great on your car (which is very very clean!)

so the turbo mufflers are too loud on the highway??
I was thinking of opening up my exhuast but i dont want any noise crusing down interstate, mainly at 70-80 mph.
If its a rumble that will put you to sleep i defenitely dont want to do it......

Currently I call SW Iowa home...and by SW Iowa I mean I can look south and see houses in Missouri and within 15 minutes of Nebraska. Lived in the DSM metro area for about 6 months last year but then moved to Ohio for work, then to my current spot.
Well, got the Flowmaster Super 44's installed yesterday. They sound really good idling, starting off and up to 3rd gear. 70mph on the highway, they dont really drone out the cab of the car. I mean.. you can hear it, but not enough to give you a headache or w/e. I did keep the resonator after the cat intact. I just wanted to start with something simple.
The old cadillac exhaust were cut off at the Y-split after the cat/resonator. I also had the guy extend the stock chrome tips out to be flush with the exhaust molding openings. Before, they were tucked in there about 1-2 inches from Factor. The 44's costed $100 each and labor was calculated at 1.5 hours. It took us about 2hrs15min cause we were BSing some in the garage. It was $350 after taxes. Over all, Im pretty stoked about them. I think I will have them remove the resonator next week ($30 dolla job). Just because I want more grumble out of it! Im a young chap, and I like the sound!

Heck yeah man glad to hear it. Id also love to get new exhaust for my 95 eldorado, but seeing as Im having trans issues i guess itll have to wait. Id love to hear a sounds clip of that corsa or brola exhaust (preferablly on a northstar) you mentioned earlier Warmarshall2nd.
Bschorr, I also would like to hear a sound clip of these.
Here you go, Fatboi. Corsa's site has the sounds for all their catback kits (at least the ones I've looked at). There are several different clips of the exhaust under multiple conditions- idle, rev, launch, drive-by, and dyno.

The problem is, the exhaust kit for the Seville won't work on an Eldo because the plumbing is different. You can modify it to work, but it's still going to be difficult.
As Gizmo and others will say, you can get a set of dB mufflers to replace the stock ones. They sound nice (there are a few sound clips of other cars with them on the site as well).
As far as the exhaust is concerned, GM did a good job. There are a couple things, in my opinion. The plumbing BEFORE the cat is one of the areas. It flattens out a bit to fit over the oil pan. I haven't looked at it in depth, but there's probably a way you could reroute the plumbing. Not a big change and won't make that noticeable a difference I'm thinking.
Also, I'm unsure on this one, but the Y joint seems to be a little sudden. You might be able to improve it by putting a more gradual split in? I'm not an expert by any means, though, so I'd ask for some other opinions... Again, it won't provide that noticeable a change.
So basically, if you want a good sound and slightly better performance, replace the mufflers with the aforementioned Corsa or Borla.

Here's another take on the exhaust thing.
I did the CORSA on my STS in 11/06 and couldn't be more satisfied. That said, if you find some of my old posts on this, you'll see that the OEM system is good, but not great. The under-transmission exhaust crossover is there to stay, and there's precious little you can do about it. BUT, if you're determined to get the most out of the engine as delivered, then get to a GOOD exhaust shop and have them mandrel bend up a s/s cat-back for your particular car. Why ? Because the OEM system is bent and jigged on a roll pipe bender and some of that 2 1/2" pipe winds up crimped down to 2" and some of the 2" pipe winds up at 1 3/4". The original cat is just fine - it's a honeycomb ceramic affair, just like the so-called high flow units. From there back, lots of room for improvement. 3" to a smooth 2 1/2" Y, decent mufflers and tips - the muffler piping can go to 2 1/4" because you're splitting the 3" main pipe to 2 pipes which, with both at 2 1/4", have more flow than the single 3". Shift to a straight-through resonator at the same time - leave it out and the new system will drone you out of the car.
No, a good job won't be cheap, but it will be noticeable up near redline shifts.
Take a hard look at the Y and piping bends on my original STS system. Now zoom in on the CORSA parts on my workbench - the Y and tip bend transitions are far better than stock - same principle as blending pipes into header collectors for low restriction.
