Starlet ep91 exhaust

[Jakub k]

I've got a starlet ep91 na and I would like to keep the standard exhaust manifold and the whole exhaust system standard but I would like to change the back box to something with a larger exit, 2.5" perhaps, what diameter is the exhaust system on a na and what inlet would I need to the back box? Hope it makes sense 😂

It's around 1.75" I beleive.

I've a universal backbox here I had on mine. No longer needed as I'm going turbo
