bravo turbo clamps

[toomany]

i know this had been discussed ad nauseam before but i couldnt seem to locate prior posts. regarding the bravo turbo clamps - do both the welded and riveted need to be replaced after 2 torques or is one able to be used past the 2 torque limit? i need to replace the tailpiece section of the exhaust due to heat erosion at the tailpipe bend but want to make sure about the v-clamps before i venture into it. last price i got was 2k per, which is ludicrous in my opinion. i got the entire exhaust section from plane exhaust in fl for $1200 - they did a fantastic job on the bends and welds, we'll see how it mates up.

@toomany Only the riveted v-band is approved for installation, P/N NH1009399-10 (Aeroquip) or 40D23255-340M (Textron-Lycoming).

Here's the SB from 2004 that established the requirement.

And here's the Lycoming Service Instruction that explains how the v-bands are to be installed.

Yes, the riveted clamps still need to be replaced after two retorques, and as @Rick Junkin mentioned, that's the only clamp allowed since 2004.
