Anyone familiar wth the Remus exhaust for the 997? How is the sound and build quality? Any drone? Anyone have any sound files?

Thanks,
Jon

 

I just put one on my car. If you want quiet power it is the way to go.
I have AWE headers and cats. The AWE Muffler was too loud for me inside the car especially, but I later found out AWE has instructions to minimize this.(I bought the system used)

I put the stock mufflers back on leaving the rest of the AWE system on - The noise inside was gone but you definitely heard the exhaust - Significantly louder than the stock.

Sounded great going underneath a bridge or through a tunnel.

Now with the Remus Muffler and the other AWE pieces it is as quiet as stock.

I can hear the air being sucked into the engine now and the road noise is back to being louder than the exhaust.

Not for everybody but I like it. Quiet performance that won't draw the attention due to noise.

With my mods the car will push me back in the seats.

 

Wow dndodd !

THAT'S THE feedback I have been wainting for long !
With AWE Headers & Cats + Remus Muffler you are really as quiet as stock ? But better performance than AWE Headers + Cats + Sotck mufflers ?

Well... I'm in for a set of Remus...

By the way (sorry, don't want to hijack the thread), My car is at the dealer for GDA (oil adjuvant) C2BS plugs, GT3 front control arms, Plenum and X51 headers, I'll let you know how is goes...

What I can say after trying my associate's 997 C4S with GDA & C2BS plugs is :
- I have noticed that the car is less rough when cold, and it is really noticeable, the engine seems to be more free
- There is a little (really tiny) more or low end torque
for around 100 € of plugs and 40 € of GDA (around 220 USD), he is quite happy with the result.

In fact, it's not about massive BHP gains, but the engine feels really better, especially on cold starts.

The plugs are also supposed to give a better gas mileage, but I haven't been able to confirm it yet.

Cedric,

I have only put about 20 miles on it so far but yes. Quiet as stock.

I think Cargraphic offers a quiet performance exhaust too.

Please refresh my memory on the GDA what is it?

The brand of plugs too?

TIA.

 

dndodd,

The GDA is an oil adjuvant produced by a French company (mecatech) which is used by many racing teams. It is supposed to reduce engine frictions. I am giving it a try, as to the C2BS plugs, because a well know french Porsche magazine (hope that's correct) have proven their merits on different cars and with real testing (dyno, lawyer...).

The plugs are in fact NGK ones machined by C2BS (french company too) with a patented process to improve their efficiency to get more low end torque and a better gas mileage.

For the small price, I'm happy to fell the car running better on cold starts and hope for the better mileage :-) No massive BHP gains anyway.

May you just confirm that you get better performance with the remus mufflers than with the stock ones ? (on your AWE setup)

Is the performance the same that you had with your full AWE setup ?

thanks a lot

Cedric

Cedric,

By feel alone on both counts I would say yes, realizing the mufflers themselves don't make a big difference.

So far I really like the way this combination runs and sounds(lack of sound)inside.

I am really not sure how it sounds outside the car I will assume it is quieter because it is inside. I haven't lowered the windows yet.

I will see how long it takes the wife to notice. She definitely noticed the last two set ups. After I had taken the AWE muffler off and put the Stock Muffler back on she asked if I had changed the muffler I said no just the Cats. She never said anything about the AWE muffler but was only in the car once with them on but she said she could hear me coming and going with both set ups.

So I expected a change in the sound when I put the Remus on just not as quiet as they are. My brother had them on his car at first with Stock Cats and didn't notice any difference in noise in fact I think he thought is was quieter but I need to confirm that with him. I exchanged my AWE mufflers for The Remus and my brother sold the car to his neighbor who likes more noise.

This may be an answer for a lot of people. I personally don't mind the sound of the stock 3.8. Actually think it sounds good. BUT, would like to see some weight reduction AND increased power. From all the posts here it seems that the AWE 200 cell cats are the key to power gain but when used in conjunction with AWE or other aftermarket mufflers can be too loud for many people.

Is there a weight advantage with the Remus? Do they claim any power gains with the cans alone?

Its this kind of info that makes this forum so great. Wife says' "What is that website you are on 24 hours a day? Porno in disguise?"

 

LeNoah,

www.maxmoto.com distributes Remus. Alex at Shark Werks sells them.

I couldn't find the online info but if you contact them I am sure they will e-mail it to you. From memory they claim there design improves flow by 80-90%. I think that is for their complete system.

Weight savings is about 1Lb per side.

If you want quiet performance I would recomend just what you said AWE CATS and a REMUS muffler, but I would also change the headers. I had an E-Bay/Suncoast on mine and probably wouldn't have changed it but I got a good price on a complete used AWE system. The AWE Primaries and Secondaries are all bigger than stock or the E-Bay Headers. Another option the x-51 header.

AWE put allot of time into the engineering of their system.

 

Thanks a lot David. I'm gonna look for a pair of Remus... :-)

 

Not too sure about changing the headers. I've done a lot of searching on this site and others and find very little evidence that headers do much. In fact have seen some cases of loss of low end torque in exchange for a small boost at the very high end. Certainly not what you want for a primarily street car. In almost every case and every manufacturer, useable gains come from the cats. Larger diameter tubes is not necessarily the answer on a street car. So if I can find a muffler that matches well (for sound quality) with the AWE cats, that is the way I will go.

 

I guess I am a little confused. If everyone is pretty much convinced that the car does not get any increase in HP with mufflers, and you are wanting to keep similar to stock loudness, why switch at all? If the cats increase HP, but do not necessarily change the noise level, why not just swap out cats and leave stock mufflers? Help me out, am I missing something?

 

Piper,
That may be a good option. I've heard from some that the combo of AWE cats and stock mufflers is not a great sound, but that is subjective. Also if aftermarket cans are lighter, that's a good thing. It's always good when you can reduce weight at the aft end of a 911. All that being said, the sound is a personal thing and you just have to find what works for you.

 

Piper,

I had all AWE H, C, and M then I took off the AWE Muffler and put the Stock Muffler back on. It was still significantly louder than stock. You definitely hear the exhaust but their was no boominess or resonance inside the car as their was from the AWE Muffler.

Bottom line adding AWE CATS and not changing the muffler will increase the noise level. I didn't mind it that much it really sounded good doing under an underpass or through a tunnel etc. So if you want increased noise and power my best recommendation is change the cats first.

Knowing I wasn't going to use the AWE mufflers I traded for the REMUS.

I now have a quiet car with hi-flow mufflers, I am very happy.

I think it runs better, but for me it just might be the change in noise creating that impression as I have not dyno'ed any of the changes I made to the car.

If anybody is interested AERO996 has a used set of Remus mufflers for sale for a 997S, in his words the were not loud enough for him.

He PM,ed me about a week ago as he saw a post where I as interested in a set of Remus mufflers.

 

Well, interesting David. Do you know how much he sells them ?

Thanks

Cedric
