I'm thinking of buying one of these as my Group N Mongoose system is too loud to get into many track days. Does anyone have the decatted Magnex system and do you have any trouble with noise regs?

Ta in advance

Andy

 

I'd like to hear info on this as well. I've got Magnex backbox and centre section. A Scorpion downpipe.

It sounds loud but I've yet to test it.

Thanks

Sonu

 

I've got a Falkland Downpipe with a Magnex Centre (with silencer) and backbox.

My car got through the Noise section of the MOT without any problems!!

Hope this helps,

Mark

 

i have a Magnex 4" round end B?Box, am having a centre section fitted this weekend at HALFORDS (£91.50 as they said they would match the price of Roadrunner Motorsport Nottm) plus they will fit it free!!

I will tell you what it sounds like, but does anyone else have this Magnex set up?
Whats it like for MOT's etc also loudness again???

 

Soon to be a popular abbreviation,MME6 {my mates evo6}has one fitted and has been measured at 96 and 98 dba at castle combe and oulton park.I know its a completely different car but may give you some idea.My sti 3 with full SAS {aldershot} system gave 98 dba at oulton park LTR meeting last friday and i reckon it is loud.

 

Salsa-King,

Do ou really want to take your car to HALFORDS to have a centre section fitted this weekend?!?! Talk about taking it to a specialist!! Make sure they don't fit a fiesta centre section instead .

 

Make sure they dont fit a windscreen wiper by mistake

LOL LOL LOL
don't worry, i'll be there in 30mins to have it done, the reason i've gone there is that the Manager has a WRX, SIDC mender and IS interested in cars!!!he also ordered a Magnex centre section for this Scooby at the same time.
He also knows Mike Tuckwood.


have every faith the fiesta exchaust will fit fine! LOL

Cem
are you still up 4 taking me round in the evo6 at Donno (12th Nov)?
if they fit wiper blades as well thats good! could do with some new ones 4 winter!

it's fitted, not done much driving with it yet but,
not as loud as i thought! sounds good though
does seem to be pulling quicker (or is it me thinking it is?)
want to get someone to drive round the block noe to see if i think it sounds good when I can her it! from the side of the road, (to simulate others hearing me!!!!)

 

We have had our magnex for ages now ok it sounds loud but not had any problems with mot's etc and now have changed from decat with resonator to Magnex straight through pipe and it sound the dogs B*****s poping and banging

ps. Good old Roadrunners to come up with the cheepest price yet again.

Right,

silly question time. What does the resonator do?

Does it affect performance?

Thnaks

Sonu

 

yes
whats a resonator????

i've now got the Magnex centre (de-cat)pipe + B/Box, inside the car i carnt seem to think it sounds any louder!!!
and when i asked dad to drive round the bloke for me it did't seem much louder than when i had just the back box on!!!
or is it just me????

 

have disided it is quite loud, not on tick over though, but when driving at certain revs.
heard they guy who sold me the centre pipes car, he had pipe fitted at same time, but has a (sirbring)???? b/box and on tick over its not as blowy as mine makin a noise!!!
will hear anyones next sunday at donno if you go.

 

Salsa,

Halfords (Mansfield)priced me up a Magnex "cat back system" £208 fitted. They say the back box is not available separatly, Magnex web site seems to agree with them. Did you manage to get a Magnex backbox?

You can buy the Magnex backbox and centre sections separately. Of course they would like you to buy both at the same time

Judging from the price you've quoted, I think things are a little confused. The Magnex backbox is around £200 and the centre section with resonator is approx £110.

It depends on their definition of what 'from the cat back' is. Is this the main cat in the downpipe or the secondary one fitted in the centre section?

I now run a Magnex backbox and as of today a decat centre section with resonator (thanks Steve ). It doesn't sound that much louder on tick over, but rev it a little and it takes on a nice growl and I would agree that the turbo does seem to pick up a little quicker.

The resonator BTW performs a similar task to the one that is fitted in the front wing. It reduces noise. Some people have reported that the cabin gets very 'boomy' when you fit the straight through centre section - hence the reason they now fit a small resonator. A lot depends on how much you drive the car, but I would recommend you go for the one with the resonator (in fact some companies will no longer supply the non-resonator version, because of the number of complaints).

Chris

Downpipe next....

 

Thanks Chris,

More investigation required I think.

If the centre section removes the second cat will the first cat be good enough to pass the MOT on its own?

Cheers
Lee

 

Lee,

The first cat is the one that does all the work. The second is there for noise supresion (why you would want to supress the Boxer Beat I don't know.) and to clean up a little more.

So yes, you should fly through the MOT.

got the 4" round end Magnex B/box from RoadRunner Nottm last year £218.50

Halfords at Netherfield sold me and fitted Magnex centre pipe for £91!!!! as this is the price at Roadrunner anyway (they match the best price!!) (i have the fitting instructions that were in the packet from the Magnex C/Pipe so i know its Magnex like the Back Box!!!!!!)
e-mail me and i will send you a pic of the tail pipe.
are you at Donno next sunday?

chrisL
where is this resonator thing?? is it on the centre pipe? or is it an airfilter?
as when i saw my centre pipe fitted last week, i thought it still had the 2nd cat still on it, but they said it was a sort of silencer! but still let the flow of air throught the pipe a lot lot better than when the 2nd cat pipe was there!

 

S-K

Yep - that bit that looks like a cat is the resonator. I assume that the straight through centre section (not having seen one) is exactly that - just a straight piece of metal tubing.

As you said, I doubt that you would be able to tell that much difference between a resonator and non-resonator centre section. It just a case of how much noise you want.

Chris

 

Does anyone know how loud/ quiet a Magnex back box is compared to a Scoobysport one. I have a full SS exhaust on an STI5 and it is pretty LOUD, attracting the wrong sort of attention when travelling quickly.

ChrisW.

 

Chris

In terms of looks, they are very similar. In terms of sounds, I would say that the Scoobysport one is louder. Get yourself along to a meet and have a listen, you are bound to find all sorts of exhaust systems.

Cheers

Chris

 

S-K

You can still get the centre section without a resonator (but I think you will find it is a special order). As I mentioned before, some suppliers simply don't give you the option as the non-resonator CS can be very intrusive. It really depends on how many miles you do and how loud you want it.

should i have had the choice of it with or without that resonator thingy???
are all new Magnex C/pipes now with this thing that still looks like a 2nd cat?


but i like the sound of it the more i hear it now, getting use to it more.

 

hi,

don't know if it's any use but I have a sample of my wrx with a 3 1/2" round magnex back box and magnex mid-section. Various
formats are available (mp3, low quality wav, high quality wav).
