Also, don't change the catalytic convertor without a tune. You can change the cat-back just for sound, if you want. But if you're just changing for sound, then changing either the middle muffler (or remove it) or changing the rear muffler will be enough to get a reasonable sound increase without going overboard.

In my view that is an improvement. As Keith is getting at though, your tune is still targetting a set boost level so peak power won't be any better.What you want to avoid is making it so easy for the turbo to spin up that it boosts beyond what the ECU seems deems is acceptable based on the stock tune. That will throw an engine light and shut down your fun.Mine hasn't done that, but I reckon I'm cutting it close and am planning to tune it and increase target boost. The BA turbo is different to FG so don't assume my experience will be yours. If I was you, I'd probably do either the cat or the cat back, but not both.Some people claim that any exhaust change on a stock tune risks detonation and engine destruction, but personally I think they have read too much interwebs.
