EDGE Exhaust Dyno Results are in!

[Erik@EDGE]

We have been playing with a couple of aspects of the design and wanted to get the dyno results out to the world. These results were acheived in a single night, on a stock 97 m3 with cats. The only modification to this car was a Superchips Flash update about 6 months ago that didnt show anything on the dyno, so we are assuming it had no bearing on these tests.

Tests were done with about a half hour in between, with our Quiet, Loud and an OEM system bolted up.

We are doing the same tests with a 95 325 today.

Bottom line...We all know that exhausts don't make much power, no matter how much you spend. The factory stuff flows great. They look great, sound great, save about 25lbs, and actually MAKE POWER, for $399. Call to order yours today!

[JUNGLISTluder]

so you raised the price because you have dyno results now?? :confused that sucks.......

[Erik@EDGE]

We raised the price to cover the expense of building them and boxing them properly in order to ensure they arrive safely. Our introductory pricing has been out there for several months, lots of satisfied customers and positive dyno results allow us to get what its worth. We are still significantly less expensive then anyone else.

[Zoso]

Any reason why there are no EDGE results under 2600 RPM?

[Erik@EDGE]

Just a matter of where we started sampling, thats all. We normally start sampling at about 3k, so the oem one was a pre-mature trigger :D

[Erik@EDGE]

We were really trying to improve the midrage, and with the Loud version you can see the substantial gains from 3-5k for TQ and across the board on HP

[techno550]

$400 is still an excellent price. Especially for something that works.

On the dyno numbers, would it be possible to get runs that started from much lower? Say below 2000? Just to see the difference (if any) in torque down there.

[mjvela]

any sound bytes of the different exhausts?

[mjvela]

I checked your site for the bytes.

What do they sound like at Wide open throttle? If you were going to rank your product vs. supersprint, remus, and uuc for loudness, how would it go?

[m3fosho]

I was at edge today while they were dynoing their exhausts on a 325...The "loud" version exhaust sounded incredible during WOT.

[MWhip]

Big ups to a company that actually posted to the public their back to back real dyno results....

[Erik@EDGE]

Techno, We'll be sure to do that with the 325. The mule that came in today (my co-driver's 325) had a custom exhaust from the headers back and no hangers to mount up the stock center section so we didnt get the tests done. Maybe next week, but with Nats, hard to say.

Probably slap Gordon's car back on there for some low RPM pulls. Problem is that 2k in 4th is pretty much bog city, but it will be interesting to see.

On the loudness meter. I would say SS is quietest, then remus, AA, stromung, UUC. Those are the ones I hear lot. Our quiet one is louder than remus, maybe a about AA, but totally different tone. The Loud version is on par with UUC.

what are the dimensions of the canister? diameter, length, and weight of the entire unit?

and do you have any comparison pics of the canister size compared to stock.

reason i ask, is i love the sound of my aa gen3, but the canister IS HUGE, and it is only marginally lighter than stock.

Mike, I'm curious to know why its necessary to know the power output below those RPM's?

In my experience, in nearly *any* tune, these motors bog at those RPM's. In fact, I don't even like making WOT pulls from below 2k, simply because of the high load it puts on the motor. On customer cars, generally with custom software (maybe advanced timing...) and such, the low-RPM high compression 'pinging' is enough to make some people nervous. The only time you will ever dwindle at those RPM's would be from a standstill, otherwise, higher (and friendlier) engine speeds are only a downshift away...

[cheech]

I'm stilling waiting on a call back from Edge about the exhaust.. :rolleyes

[Erik@EDGE]

Cheech, we have one in stock with your name on it. Call us tuesday and we can get you scheduled.

[Bernanke]

not bad, loud version seems like its worth the money, dunno about quiet one though, looks exactly like stock.

[F Dogg]

the exhaust sounds pretty sweet. More sound bytes and more pics would be great!

do you guys make your own mufflers? Or does someone else manufacture them?

And how much more for the cat eliminators?

Steve

Exactly! If you are trying to go fast, why on earth would you be down below 2500rpms?

By the way, I have all the stock exhaust hangers here at home. If you guys need to borrow my car for a few days to test (or re-test) I can leave it with you.

can you answer this???

Its not necessary to know, but that doesn't mean I don't want to know. :) For the quiet version, I doubt anything changed down low seeing as up high there wasn't much change either. It is on the loud version that I'm most curious. From 3k-5k the loud makes a lot more torque, which is where its really important. I'm curious though to where the difference is between the two from ~idle to 3k. I think there may be a good chance of no appreciable loss in torque with the stock cats and mid resonators still intact. I don't know for sure though. (not that one car's dyno would be good proof either way, but it would potentially be a very good indicator of which way things go.)

As a side note, people run chips with enough timing to ping at low RPM under high load? What about driving a car like that on the interstate? 50mph in 5th is in that region, no? Sounds like potential bad news.

I don't think the quiet one is only for its performance gains. There isn't much of a HP gain, but you do shed a good bit of weight.

[Serious]

loud is the only way to go.

any sound clips of the full exhaust system?

[JClark]

More sound clips would be great. Anyone with personal experience?

[slcook54]

If that was a 97, I would be interested to see the gains on a 95 M3.

[JClark]

ditto

[mazur]

Can we get a measurement on the tips? Cause in one picture it looks like they're nice and large. But in the other picture (shown below) they seem small. :confused My stocker tips sit closer together than that.

[ndehlinger]

They've changed the exhaust a few times as it's been developed. Their new ones I've seen have nice fat tips. The one in the photo above I believe is an early prototype.

[Erik@EDGE]

Noah is correct, the new tips are larger and closer together. Forgive us for being slow to respond, Gordon left for Topeka yesterday and I am on the way tomorrow, so we are swamped getting the last orders out and will be out of comission from tomorrow through the 19th. We will do our best to stay in touch on the road, but if we miss you, shout at us on the 20th!

Wish us luck! :buttrock

[s_ribs]

I listened to the sound clips on your site. It sounds great! A few more would be great though from different perspectives though. Looks like a great exhaust and a great deal. I'll keep it in mind when I'm buying an exhaust down the road.
Seth

[JClark]

Take video of the Edge team at the races! Now THAT's some perfect exhaust videos.

[CodeMonkey]

Hey, where's the 325 dyno charts?

[Erik@EDGE]

Sorry guys, we ran out of time to do them. We will get some test going again now that we have a 325 to test on.

[B.Watts]

What about driving a car like that on the interstate? 50mph in 5th is in that region, no? Sounds like potential bad news.

Sure, but how many people put their foot to the floor from 2500 RPM in 5th gear?

[Suneal]

The Loud version is on par with UUC. TSE or System-U? And the clip of Gordon's car on the site is with the quiet version, correct?

[Erik@EDGE]

On par with the System U I used to run. Gordon's clip is the quiet version on a 3.2.

[M3corey]

ive had an edge exhaust for awhile now .. i dont know what i have .. quiet or loud .. love the tips .. i hope i have the loud version lol

[MightyAl]

what diameter is the piping that is used on this system? I am lookign for something to use in a turbo application and am trying to avoid fabbing up my own cat back.

[eightballrj]

Has anyone found any DECENT sound clips. Kid's is too short. I am really intersted in this exhaust but dont know which to get because I want to hear it before I buy it.

Richard

[JClark]

Im also interested but no one can give any information on it.

[GreekM3]

is there a stainless version coming out? Any way you guys can do a comparison to an AA?

[accel junky]

Any updates on this exhaust system? I searched for the sound bytes on the site but couldnt find them.
