Just got my gt91 and was wondering what size the turbine outlet is so I can order a v band for it. Any one is know what size it is. A 4" is too small and a 5" is too big. I assume 4.5", but wondering if anyone else has ran into this. Thanks, Josh

You will need to get the v band specific for the Garrett turbine. I'm sure Forced Inductions has them.

Ran into the same problem. You will need the 5" version of this one.

A 4.5" will not work, as stated, it is a specific size by Garrett. U can get stainless or aluminum and u can get them to accept a 4" downpipe or a 5" downpipe. They sell either

Clarification, I ordered the 4" downpipe version from racepartssolutions.com I already I had a conventional 4" and 5" and they were not the correct size.

For my GT88 i had to order the 5" version on the link i posted. Then i bought a 5"-4" reducer pipe so i could make my 4" downpipe.

Oh and how is the 4l80e treating you? Just got mine installed with the Transgo HD2. Hoping to get her finished up and start tuning around july....

I drove it for a few hundred miles and it was great. I pulled the blower off the car and sold it and now doing the gt91 setup. I got tired of the meat grinder sound from the f1. Glad to hear you got yours together. What converter did you get?
