The TPIS is more of an oval opening (80mm x 90mm?) and is basically used with their own modified LS6 'wide mouth' intake (unless they also have a round one?) and the FAST is a regular round 90mm opening.
Quality between the two is subjective.
I personally would use the FAST with the FAST intake and the TPIS with the TPIS...not to sound obvious or anything.

I went with the TPIS because it fit better than the FAST T/B, the FAST T/B doesn't match up to the FAST intake very good and the TPIS 90mm does. The TPIS 90mm is not oval it's round and is a great quality T/B and fitfits and looks great.

Yea I should of made that clear, TPIS didn't come out with the round one until FAST was having big problems with their 90mm T/B.
