Looking to replace the small pressure pipes between the turbo nipple outlet, wastegate inlet and solenoid. Some people refer to these as vacuum pipes, but in reality they aren't as they are pressure pipes, so the complete opposite. The only people I found who correctly list them are Cobb Tuning who call it Silicone Boost Line.

Is there anyone in the UK who supply proper Silicone boost line with a nice thick wall that won't expand as it gets hot and pressure is applied.

 

Alyn at AS performance is where I got mine from

 

I got mine from a cheap kit on ebay, working like a charm for more than a year, and lasted over a 40º trackday.
