I am going to install an aftermarket wastegate. I have the GDP Progate with a 38 mm TIAL wastegate, and I ordered some gauges, boost and EGT. The wastegate should bring down EGT temps by allowing more flow, and the boost level can be adjusted. I am going to gut the cat and tie the wastegate outlet into the exhaust pipe. I want to be able to use some higher levels on the Smarty without any head gasket issues.

 

I notice you have a steering brace on your sig, was it worth the money and did it make a big difference? Been considering putting one on mine, I havent had any problems with death wobble as of yet.
