Aurora 40........i sure have heard great things about the exhaust you have.....just really didnt want to put the money that they cost into a used car. You bought your rora new didnt you? If i could afford to get a new one.....i'd spend the extra dough that you did on a great setup .....of course if i could afford to get a new one now......i'd be SOL wouldnt I......hehe

Flowmasters are sort of an odd muffler. They use baffling, much like a Dynomax Super Turbos or an OEM, but they don't have serious bends in them. An OEM or dynomax will typically have 180 degree bends and perforated tubes. Flowmasters have sort of triangles like you said. So they tend to be pretty loud and flow pretty well. But they still have baffling. As an alternative, many mufflers use packing like glass fibers (not just round glasspacks, either) and a tube with lots of perforation. The packing tends to absorb the sound and they are straight-through in design. However, a perforated tube won't flow quite as well as a solid one. These mufflers tend to flow quite well and are not always very loud depending on the perforation and material. They are however usually pretty heavy. I believe this describes Magnaflow mufflers. The Dynomax UltraFlow or whatever mufflers are of this type. The Magnaflows may flow slightly better or the same as the Flowmasters, but probably aren't as loud as them. Flowmasters are pretty loud... I suspect even with the resonator you may have some noise at cruise, but hopefully more burble than drone. Like I said, you really may want to put the resonator back in.

I took my resonator out when i installed my 2.5" cat-back system and i didn't really notice any unwanted effects. although i can here my car a bit at cruise, it's not bad though (at least in my opionion)

I think i am going to eventually.....they are pretty cheap so i'll just geta new one. I also used 2.5 pipe all the way....till it hit the factory tips that is. Overall I am very happy with the performance and sound......I think sound is a preference thing and not wanting to misslead anyone it really isnt that loud. Not like the ol big v-8's that is........and it sure as heck dont sound like like a 4 bannin rice burner/weedeater either. It is deep and mellow.....thus the low hummmm when cruising.

If i could afford to get a new one.....i'd spend the extra dough that you did on a great setup .....of course if i could afford to get a new one now......i'd be SOL wouldnt I......hehe It wasn't my intent to disparage any other product. And I definitely don't think everyone should just buy a Corsa. I just wanted to point out the differences in the various systems. What's important is that you get a system you are happy with. And any exhaust upgrade is sure to improve over the stock flow, and help free up that torque and subsequent horsepower from your mill. Supa, you went with Super Turbos, correct? My memory's not the best, but that's what I recall. I think Flowmasters in combination with no resonator will be more pronounced... And everyone likes a different amount and type of sound. Here are some picts of various types: Magnaflow: Dynomax Ultraflow: Dynomax Super Turbo: Flowmaster 40, Delta 40, and 50 (note quieter = more baffling): You will probably find the Magnaflows and Dynomax Ultraflows are fairly heavy, heavier than the Dynomax Super Turbo and the Flowmasters. This is due to what's inside. My Corsas were very light. Greg actually had his installer make fun of him. He laughed at how light they were as if it meant they were cheapy. Greg said he stopped laughing when he fired the car up... Sometimes I feel like I have to be defensive in exhaust threads just because I shelled out a lot for mine...

Do you have any soundclips?
Right now I am leaning toward Flowmaster "Original 40 series" and i was just wondering what they would sound like. I know you have the 2.5 inch pipes all the way and without the resonater. But it would give me a pretty good idea what mine would sound like.
Thank You MpWarrior21

I actually have no way that i can think of to get a clip. My camcorder is not didgital.......my camera is but does not record sound.......and i dont have a laptop. I do have a small didgital voice recorder.......but no pc cable....dont even think it came with one? Ill ask some people andf try to get one. It wont however be done very quick, as I own my own cabinet shop and am very busy till christmas.....very sorry. Regards, Grant

Thats perfectly fine with me. I was just wondering how it would sound. I was curious. The insurance guy is coming out Wednesday to look at my car. Then comes the check then I'll put on the Flowmasters. i think is a pretty safe choice.

I went to the local Wisconsin Muffler shop and got an estimate. 2.5 inch pipe from the resonator all the way Y-split is $100. 2 connecting pipes are $20 Each. and 1 Y-pipe $70. Totaling $210 not including mufflers or tips.
For the mufflers $170 per muffler for Magnaflow. $150 per muffler for Flowmaster. Plus tips either Magnaflows $110 or $100 each depending what tip I get. Totaling $540 for the Magnaflow muffler and the cheaper tips.
These prices are crazy right?!

I would say so. I was quoted almost $500 from a shop, so I got back in the car and laughed all the way home.

MpWarrior21wow, i bought my mufflers for 35 dollars each, Dynomax super turbos 2.5", i bought pipe for i believe 40 dollars for 15 feet. brought it all to the exhaust shop and he quoted me $110 dollars for labor.so 110+70+40= $220 or so ;D. depending on how close you are to Minnesota, it would be worth the drive, its in Forest Lake Minnesota, if you're interested let me know and i'll get you the number, the guy is super nice, he also said that i shouldn't have bought the pipe for it cause he gets his cheaper and it's better quality.

Can you bring your own mufflers? You can get them from somewhere like www.summitracing.com or something probably for less. Why do you want to do the pipe, though, if you are keeping the resonator and such? Couldn't you save a bit and just swap the mufflers and tips? $220 for tips seems pretty steep too, but I dunno...

Im not sure if I can bring in my own. Also Im not sure if the resonator would be left on. Im not really sure I need to talk to the guy again. I need to see how much money I get from the insurance agency and see what will happen from there. At the Bumper to Bumper about a half mile from me the Flowmasters were $66 each. I really dont know why they would be $150 at the Muffler Shop.

Also, look at what guage the tubing is......mine is thicker than say what comes stock on cars. The guy that did mine pointed this out and alot of franchise/big commercial outfits dont generally use this type of pipe. I think I would seek out a good independant muffler/brake shop. Talk to the owner They "Y" really isnt all that difficult to make just a matter of him making the right cuts. This shop owner that did mine says he does them alot, even on cars getting cat backs that didnt origionally come with them in the first place. I do know that I was charged 70 dollars each for the mufflers which left 160 dollars for the new "Y" and ss pipe. It took him 1 hr. and 15 minutes. For a grand total of $300. Everything was symetrical (sp?) and the welds even look nice. Hell, the tips are at least on center of the bumper relief now.....something ALOT of stock aurora tips from the factory were not. Good luck, and support the little man.

Hey guys, what exactly is the "resonator ?" Where is it in relation to the cat ? Does anyone have any knowledge of Borla Mufflers ? There is a shop here in town that does Flowmaster and Borla. Is everyone doing 2.5" pipe from the cat back ? Does this resonator restrict the air flow ? I am used to my old truck, no cat, just a couple of mufflers and 3" pipe..ha.

The resonator is right behind the catalytic convertor. Borla makes a quality product from stainless with a million mile warranty. I don't believe they make an Aurora system. I think they use glass packing in their mufflers, but I'm not actually sure. The guy who started the company (Alex Borla or something?) had an Aurora back in 1995 that he customized and lowered and had a progressive nitrous system installed on (about 50hp if I recall).

Do you have to have to resonator on ? Or can I pass emissions without it ? I am lost as to its fuction. What size pipe would everyone recommend ?

Post by Aurora40 on Dec 17, 2004 10:09:43 GMT -6
You don't have to have it on. It cancels out resonance, which is a very annoying buzz/hum usually in the lower rpm range. You can hear it on a lot of cars from the 80's when cruising on the highway. A resonator helps a lot with this, but doesn't really restrict flow much. You can pass emissions without it. Whether you can stand driving around without it is up to you.

like i've said before, i don't find not having a resonator to be annoying, i used 2.5" pipe. I think our cabins are very well insulated for sound though.

At Wisconsin Muffler I tried out both the Magnaflow and Flowmaster Original series. I liked the sound of the Flowmaster better. Ill try and get a sound clip of them once i get my car back. Its still needs to be looked at because of the accident. Hopefully I'll get the car back tonight.

2.75" pipe to a 2.25" y pipe into 2.25" dynomax race series (1 chamber) mufflers and tips off an 04 gran prix.
no resonator either!

Opinions on using a "racing muffler" as a resonator? They're totally straight-through and I can imagine them doing the same thing as a resonator, cancelling out the unwanted noises especially coupled with actual mufflers down the line.

I have Dynomax Super Turbo mufflers and i got the resonators cut off. it cuts out a lot of the nice sound.
I dunno, i shold have gotten the Dynomax y-pipe put on too, that probably would make it sound twice as better than it does now. At idle its a nice burble though, classy V8 sound. Very nice. When flooring it and winding the gears it sounds VERY loud in the cabin, and i love it that way.

i've said it before and i'll say it again. dump the resonator, run 2.75 back to 2.25 or 2.5" y into dynomax race series mufflers. can't beat the sound, it sounds raped.

can't beat the sound, it sounds raped. Uhhh, is that a good thing? I guess so... I just don't want anything that sounds too loud and sloppy. I'm still considering '04 Mustang GT mufflers (I can get them for free), if I can determine what kind of sound I'd get from the 4.0L.

I've heard Corsa mentioned a few times. I guess folks are using the STS/SLS or Deville setup on the Gen I Aurora? I got a Corsa system for my Yukon and it is sweet. Can someone give me specifics on what they are doing with Corsa on their Gen I ?

whoa... after reading this i am completely confused. i had planned to go with the flowmaster. i jus want a deep low rumble like a mustang or something. what should i do about the resonators and Y pipes? i want it to sound good at idle and nice and load when flooring it. but dont want it poping or real annoying loud when going down the highway. i wanna hear a flowmaster on 1 of these.
