keeping the subaru sound

hi
has anyone managed to keep the scooby burbble on their conversions,ive just fabricated yet another exhaust system using manifolds from RJES but still cant seem to keep the sound,
its a simple set up running from the o/s round the back of the engine between cradle and bellhousing to the n/s where it goes into a 2 piece collector where the pipe from the other manifold connects , from there it goes towards the rear of the van with a 90 degree bend to send it across the front of the timing cover into a backbox ,all this is done with 2 inch pipe the backbox is 450mm long 125 in diameter with a 2" entrance and a 3" exit , engine is a 1992 2.2 legacy lump non turbo
please help

I was under the impression to get that real Subaru sound you need the turbo motor.

But in saying that b4tfink's 2.5 conversion sounds like an Aston Martin Eeeek

Keep your primary headers to around 6" to keep the rumble.
Turbos make it sound much more.

With the Nat Asps it's bad exhaust design(*) that makes the burble. In an ideal world the primary headers should all be the same length

* Done for cheapness/space

Unequal length headers as on a WRX is what you need isn't it?.

Have a look at this

Any reason you're not using a stock (or pie sliced for clearance) header?

hi elusive
what do you mean when you say pie sliced manifold as ive not heard of that, reason for not running a stock manifold is that it is a lot lower than the tsr sump ive fitted and i want all the pipework above the sump for obvious reasons now that the bus has been lowered again

Cut the angle to suit yours.
WRX headers have less "height" (compared to a Nat Asp) to them as stock. I have one but haven't played with it yet
