Twin Scroll Headers.
 

I have an MY04 Spec C with twin scroll turbo so runs the equal length headers.

I'm really missing the Subaru burble. Do any of you know of any company's doing unequal length headers for a twin scroll?

Thanks

Andy.

Hi,If you're planning in running unequal headers you better sell the twinscroll headers,turbo and downpipe and buy unequal headers and a single scroll turbo like a vf34 or bigger,otherwise the twinscroll turbo with the unequal headers it will spool worse than a vf34.In a simple answer the twinscroll turbo is designed to work only with equal length.

I never missed the burble just welcomed the scream at high revs.

As above

You would need to do a single scroll conversion
