I didn't install it, I got Pit Stop to do it coz I couldn't be bothered, thought they would've advised re: heat wrap/shields.. Anyways I took it all apart last night, heat wrapped the up pipe and inspected the turbine blades. Nothing wrong with turbo, must've been leaking exhaust from the dump gasket on boost. Found that some of the dump pipe bolts were only finger tight when I was disconnecting, plus they left the old gasket in and just threw the new one on top of it... got a refund from Pit Stop.
