Currently have a HKS full system but think it still has both CATS and a big silencer on the back box, its very quiet all the time. Hardly even hear it when idling.
Want something thats a bit louder with a nice burble but not too loud.
My last WRX had a loud system (not sure of name) but it was a bit too loud.

What exhaust system or back box would you recommend that sounds good and not overly loud?

Its a 97 STI.

Any help would be great.

 

I've just fitted a afterburner vortex backbox and couldn't be happier with it, great sound on tickover and an awsome sound under boost

 

i have a blitz nur spec r and thats mega loud i also have an afterburner vortex and that sounds great.its nice and deep loud but not too loud so id say a vortex matey

 

cheers

where's the best place to pick up a Vortex back box?

 

i have one for sale mate.its in the for sale section.the backboxs come from scoobyworld and are £250+p&p.mine is only a couple of months old and only done 150 miles.

 

i agree with the afterburner vortex, got one on mine n i love it

 

I'd buy it at that price but pickup wouldnt be an option as it would cost me about £160 in petrol to get down there and back.

Cheers tho.

 

The ninja is not as loud as the afterburner, but everyone will still be aware of what you're driving.

 

Few sound clips on view my scooby, also afterburner and firestorm if you go into my youtube videos.

 

 

will listen to some sound clips later when i'm not at work.
reckon it'll be the afterburner tho.

Do you think I should go for just the back box or is it worth the hassle of getting the de-cat centre/downpipe and having to get it changed over for the MOT each year.
I gather it will also be even louder if I get the full de-cat system?
Think it'll just be the back box i'll buy.

 

Aye, it will be much louder with full decat.

If just the backbox, then the afterburner is good.



(* Don't always have to change the decat over for MOT. )

 

centre section and back box then decide on de-cat

 

I have a full 3' HKS system on MY03 STi (decatted with headers), sounds awesome! Really loud rasp! Louder than the Afterburner I had on MY02 STi. Different sound though!

Blitz for being loud

Hayward & Scott all day long!

 

i have an 03 sti prodrive with a unresonated centre section and vortex back box(jap style) which sounds great!

 

Hi, go for a firestorm

 

Can't beat the afterburner vortex.

Andy.

 

think i'll get the afterburner back box then.

just got a de-cat centre section from a mate,how easy is this to do myself?

 

Anyone tried the RCMS system or back box ?

 

bish,i think you will find it difficult to do without getting it on a ramp!!the bolts will have siezed up at the manifold end and may some heat with a welding torch to get them of
take it to an exhaust centre,they'll charge about £15 and u won't get your hands dirty!!

 

good advice this is what i did much easier

 

sounds like a good idea, if i had ramps i could try it myself, but i dont so garage it is.

 

got the car booked in tomorrow morning to get the centre pipe swapped over for the de-cat one, if it makes a decent amount of noise difference i'll leave the back box as it is.

 

The centre section was about 3 inches too short to fit in place of the original.
It was also curved slightly different at the side towards the front.

The guy I got it from had it on his classic impreza wagon, a few years newer than my sti(saloon).

Is there a difference in exhaust length or can it be due to my particular back box being situated further towards the back?

 

Another vote for the Afterburner Vortex system.
