Just as the title says, who makes one? Where can I get it?

Thanks!

You have a few options

PTE (integral wastegate) stock manifolds or ATR headers
RPM (External wastegate) stock manifolds or ATR headers
ATR (external wastegate) stock manifolds or ATR headers

I would just order the GT35R PTE downpipe kit from E-Rue @ www.turbotime.us

Whats the difference of inegeral and external?

Also this is for the stock manifolds.
