Does anyone know how I can get my hands on the APS 3.5 inch downpipes. Will these work with GReddy turbos? Will there be a fitment problem with the (future) SGP open wastegate dump tubes? Also whats up with the 3 inch exhaust from APS? Where can I get one?

Shariff- Do I need a ultimate e-manage or can I adequately tune my Z to 600 hp with the regular e-manage?

Thanks- James

 

I heard it will be for sale late september/early november.
