After some exhaust advice,

my current exhaust is a haywood and scott, very loud, cost over £700 new.

Was fitted by previous owner and is just to loud for my taste. using car alot with kids in and on motorways and it just drones.

i fitted bung and loved the quiet tone.

whats quietest exhausts, i dont mind the burble on idle and full chat but want it as quiet as possible on longer drives,

ive seen the Varex adjustable butterfly back boxes but cant find a uk dealer.

ideally id like to change the back box only so if i ever fancy the burble back its a 20 mins swap over.

the car mapped so need free flowing.

cheers

 

H and S are normally one of the quieter brands. The only brand that I know of that is quieter is Milltek

Be careful using the bungs, they restrict the flow of air quite a lot. I tried mine with a bung and it felt like I was running standard power or less

 

I'd say Milltek or Prodrive system and agree i wouldn't use a bung again, use to feel underpowered with it fitted. Basicly restricting air flow.

 

What about the the hks silent high power system?

 

Milltek is the quietest I have heard, mine is 3" bore full decat etc and probably the quietest I have heard on a Subaru

 

when i install bung im a sunday driver, dont even boost

Il google miltek and hks.

 

Another one for milltek, really quiet system but loud when you want it to be . Have a full milltek system with sports cat and de-resonated centre section running 400bhp.

 

And another for miltek 3" system sports cat running 330 , on previous impreza's I've had H&S and afterburner vortex exhausts and this is by far the easiest day to day system to live with .

Kev.

 

Had the Prodrive on mine, pretty quiet but still had a nice tone when giving it the beans.

 

fujitsubo gikken one peice system, 94 db@ 6k rpm. Passes track day noise tests and still sets off the occassional over sensitive car alarm. They come up second hand frequently as they are too quiet for the average subaru owner.

 

MINE HAD A 3" POERFLOW NOT TOO LOUD, FLOWS WELL TOO

 

^^^^^^No need to shout. lol

 

I've got a almost new hks hi power silent system so cat back I'd sell for the right price...I payed £500+ from new for it via sumo power ... Reason for sale = to quiet drop me a pm if interested

 

Revolution ( Jetex)

Had 3" turbo back on my classic a few years back , had a good rep as being a quiet but unrestrictive system

Exhaust from Revolution is one of the quietest available.

What people need to remember is, if they have a standard unequal exhaust manifold, then it's gonna be a bit louder regardless of the exhaust fitted.

 

Revolution is defo quietest, 89db static at 4k revs on a rotated GT30R

 

Is the centre section resonated or straight through? My H&S was straight through and really boomy, but H&S offered a resonated centre section and it's made a world of difference. Might be worth a try before taking the whole thing off.

 

@crazyspeedfreakz you've got pm

 

another thumbs up for revolution

 

Replied

 

cobra 3 inch system is pretty good, not ear bleeding even with wastegate disconnected haha

Fujitsubo
