Hmm, not sure I like that idea. The flexis are the weak point and do eventually fail, maybe thats why they removed them?
But on my Invidia G200 I have had to replace them both in the last couple of years, although they were 6-7 years old and take a battering due to being FI. Not a big problem just cut out the old ones and weld in a couple of new ones, you can get from any motor factor for about £20.
BUT they must have failed because they were doing their job and 'flexing'. If they had not been there then the stress of the engine movement would be felt else where - probably the Manifold And i wouldn't want that to crack.
