Twin scroll exhaust manifold options...
 

Hi guys (&gals)

just a quick one for the EJ20 guru's out there...

I have a BL5 Liberty GT with a twin scroll setup. As warranty is nearing the end, mods will follow. For my first mod, I'd like to make it sound like a subaru :) .... I have the factory equal length headers which have tuned out the boxer rumble.

I would like to fit a different manifold which will give me the proper sound at the cost of some horsepower and throttle response. The OEM/Sti version of this manifold is a "little" expensive...

Are there any Sti manifolds that will be a direct bolt-on replacement and produce the right note?

Cheers,
Alvaro
