I picked up a Tanabe Medallion exhaust and I am also running a Racingbeat downpipe with no maincat, just a testpipe. I want to know what gains i am looking at and all. I am new to Turbo so I got a crash course in the many other things I need since it was a n/a convert I dont have the car yet or have seen it or heard it I should be getting it in 1 week though.

 

Tanabe products are TopNotch, so Im sure that you will love the exhaust. Im running the concept G on my daily driver.

 

the same as if you went with any other open exhaust, only louder.

3" piping will increase the boost, you'll hit fuel cut if you go past ~8.5psi unless you have an FCD.

 

If tanabe made a cat-back for the FC, I would buy it in a second. They have great products.

You will need the FCD and it would be a good idea to rewire the fuel pump so that it sees 12+ volts.
