Hey whats up Im plannin on Put a Star Stage II Turbo on my 97 GS with a howell rebuilt bottom end, and wanted to know what to do exhaust system wise. The kit comes with a 2.75" downpipe but I'm not sure what i need or where to go from there to have the best performence. Please help me out and Thanks to eveyone that replies

the down pipe connects to the cat. converter, add a test pipe for best performance,a test pipe replaces the cat. with a straight piece of exhaust piping, it will help your turbo flow exhaust gasses better making for quicker spool-up for your turbo and after that a 3" cat back would would be great with the turbo kit too. BTW the test pipe is hardly street legal,so you'd want to add it after you pass emissions.
