Any marks or numbers stamped that you can see?

none, other than removing the wrap

Harvey freq marked his turbo conversions but not his headers & up-pipes unless it's a very early batch , it's imposs to identify over a forum , sure Harvey & Dawn had a certain style of wrapping but that's not conclusive.....
Only power runs & dyno would give you 100% conclusion....
Do you have bill of sale , dates & location etc etc
I knew Harvey very well , there are a lot of fakes out there , so I say please if your not 100% don't advertise it as such .

I got mine from Harvey, just a reworked and ported standard manifold wrapped but not marked in any way. A massive crack eventually appeared at the junction and that was the end of it! Fitted an RCM GT Spec Gen 2 & up pipe replacement, so the Harvey special up pipe has been pensioned off too. No markings on that either.

I use the RCM GT 3 Bolt also
However I remain with the Harvey 3 Bolt up-pipe

It's all about pref. & choice can't slate anybody for that..

Most OEM Headers & ported conversions were done on trade
At the end of the day it's a manifold not the star of Gibraltar

Indeed just a manifold but my Bug made 425bhp with it fitted, with just a 2-1/2" front to back exhaust system too. Harvey always reckoned it was time to trade up at around 400. He was probably right as I blew mine apart at 425, maybe not related though!

Yea , I'd say you pretty much maxed it out
Good figure tho on ported OEM
