Simplest/cheapest first option is to replace them with new OE or aftermarket ones to eliminate them from the equation.
On SAABs Abbot Racing supply metal pipes to replace the OE "rubber" ones for that very reason.
HTH.

Son in law has just been around with his vauxhall zafira gsi - 2l turbo and it has an odd problem. He says it lacks power and on tickover it's
like it's got asthma, every second or so it's like it's taking a gulp of air - tick over is constant. The pipe between the intercooler
and the engine also flex's. If you rev it this pipe appears to collapse a bit for a short time. Don't think it's the turbo as no smoke
or screeching noises from it
Anybody got any clues as to the possible problem - what ever it is it will be expensive - lol
If it's drawing the IC to throttle pipe closed then it sounds like a blockage in the I/C.
You could try taking this pipe off and starting it and letting it idle without the turbo and I/C in line, if it idles much better without sounding
like it's choking then I'd bypass the I/C and run it like that to see if it's blocked or failing that remove the I/C and check for
blockages.
Many cars have the MAP sensors on the I/C exit so if you do bypass it then don't go driving it around to test it as when it comes on boost
it'll probably go into limp mode.

The OE "rubber" pipes on turbo installations tend to go soggy after a time and draw inwards restricting flow.

First thing I'd do is pull out the air filter. Cheap stuff first!
