3" exhaust

I have an 88 turbo coupe and was thinking about converting the exhaust to a full 3" exhaust from turbo to tip and i was just had a few questions. Where can i find a 3" down elbow that will fit the stock IHI turbo. I looked on stinger's site and the elbow says it only fits turbos mounted with the center mount header they make. Just wondering if anyone who has an IHI and 3" exhaust could help me out and shed some light on this.

Also, if I can find the elbow, can i use stinger's 3" tailpipes and stuff to complete my conversion?

(I was planning on dynomax super turbo mufflers and dynomax catalytic converter)

Stingers downpipe will work with the IHI and the 3" exhaust from him will fit. But use Dynomax ultraflos or some other straight through mufflers on a Turbo car.

They will still work? I thought that since they must be used with stinger center mount headers the turbo would be rotated and the bolts wouldn't line up? Maybe im wrong.

Stinger has a couple sections on his website. He has center mount header parts and stock turbo location parts. Make sure you click on the stock location parts and you will find the appropriate pieces for the exhaust.
