Do you find your Decat too loud?
 

Do you or your wife find the full decat too loud and what did you do about it?

yeah and divorced the wife :lol1:

No. Its how they're meant to sound.

Wife makes a constant droning noise though which I cant cure.

ok not a full decat but iv got a decat middle and a scoobysport back box and I find it way to loud inside the car (dont care how loud it is outside)
Any ideas to reduce the sound on the inside?

Turn the radio up!

Jaycee said that too.

I just told him that on msn! :D :D :D

Well that's 2 people saying the same thing, so it most be right!

You could put sound insulation in the car or put the standard zorst back on.

not after the money iv spent on the backbox

How about some nice cushions on the back seats? ;-)

Well buy a better sound system then!

i find mine ok and i've got a full scoobysport system

You might consider removing the downpipe cat and fitting a sports cat in the centre... More power, less casbin noise and itll pass its MOT. (Youll need a remap of course)

Full Mongoose de cat, quiet when normal driving, noisy with it floored. Easy to live with. Never listen to radio, Scoob sounds far better.
Try replacing cat and keeping back box? Daz.

No it's not too loud.

That makes it three! :D

Magnex Decat Downpipe, Magnex non resonated centre, Scoobysport Backbox

Not loud enough :)

Ear Plugs £0.99 per pair from screwfix direct (in bulk purchase for hygiene)?

Seriously, this is a wind up right? That's how the scoob should have sounded in the first place!!!

Why not go and buy a Civic Type R? They're not so noisy and you get a free set of curling tongs too...

Sorry, had to have a wee pop!

It all depends on what system you have...

Mine is a Scoobysport and it's loud but not TOO loud.

Some are more resonating than others. Im not a fan of the overly loud ones.

I assume this centre decat is a straight through pipe. I was advised that they drone through the midrange on cruise. Try a decat pipe with a resonator box in it or go for an STi middle section which has two boxes but no cat.

Ray,

I've got the same (but with a DP),. Yes. mine's loud in the cabin, but to get around it, (I haven't done it yet), I'm going to Dynamat the boot and probably the reaer seat and under the carpet......

Shouldn't be that pricey either.

The only downside - insulation for low loud frequency is heavy, therefore, might affect your performance slightly :)

Ive got a magnex back box, longlife centre section andjust the one de-cat. Its OK on short daps and when you know your going out for a blast but normal motorway driving it does tend to get on your pip a bit.
You could put back the cat and leave centre and back box
Or have a resonator welded into centre section
or instead of dynamat lift the carpets and chuck in old carpet underlay :)

It's to loud you must be jokeing:cuckoo:

I have Magnex down pipe and center section complete with a vortex afterburner back box :D and it's mega loud and pops and bangs like a b@stard and i love it :thumb: and the neighbours hate it:hjtwofing

dont give a sh1t about my neighbours. I love the sound from the out side but motorway driving its just a bit to much

You will get use to it and learn to love it :)

I have a Revolution 3" decat DP and system. It is pretty quiet at cruising speeds. Floor it though and you get a lovely sound...deep and bassy but not jet fighter loud :D

I had a straight thru centre and a firestorm, because the car is an ra (no noise suppression) it was a bit droney at motorway speed. Replaced the centre with a high flow resonated one and its much better and still get the raw sound from the firestorm on wot.

Ray

Know exactly what u mean Ive got Afterburner with Decat Centre and its a knightmare when cruising on motorways, was alot quieter with just afterburner

Best option may be to decat the downpipe and replace the centre with the prodrive one as suggested earlier in thread....should reduce noise.

Ashley

Easy mate, here's what you need to do and you should find it works well..


You will need the following,

A staple gun
Lots of staples
approx 50 - 100 empty egg boxes (depending on size)

Now, all you need to do is evenly staple the egg boxes to every internal surface of the car, be careful to make sure there are no gaps or the sound will come through. Now obviously for the windows cardboard egg boxes are just silly, you cant see thought them, (and i'd love to see you 'staple' something to the glass, lol), that is why they designed the seethough plastic egg boxes and double sided sticky tape, alls you need to do is stick the clear egg boxes to the windows, don't forget to ensure there are no gaps.

and voila!! reduced sound inside you car! the perfect solution. You can buy this revolutionary noise reduction kit direct from me for only £299+VAT :D

where do i send my money?
in fact i'll ben over for you right now.

different centre or sound proofing is the way to go.

Could anyone confirm would there be any difference in a PPP centre section and a decat centre section say on a MY00ppp in terms of performance?

Isnt the PPP Centre different to the standard centre???

Kinda thinking of fitting prodrive centre section back on but changing to decat downpipe instead.

Ta for any info.
