I thought I would start up a thread on exhausts since there are so many questions that are asked but no specific thread for them.
I have looked around, but not much is out there on differences in exhausts.
I wanted to know, what the differences are between the 3 turbo, cat and dif exhausts in sound, price and performance. For a WRX, what is the best option and what tuning is required.

3" Turbo back is the most efficient, but you will need to think about getting a tune done, otherwise you will be running pretty rich.

IMO, 3" diff back and cat back's are a waste of time.. Might as well do it properly the first time. Altho, I had a 3" cat back on my STI and it sounded pretty good. Economy was out the window tho..

I don't know if Dylan is still making his SS exhausts, but I had one of those as a Cat Back which replaced my RMS built mild steel that I had on first. They are a great exhaust for their money, about $650ish from memory, and lots of guys here have run them in the past. Butler also make good exhaust systems if you can afford to pay for it.

i'd personally be buying the butler built one off spanner great dump pipes those butler spec ones, might need modification of the dump splitter though if it was previously on a car with a vf turbo (the splitter length is different on a td04)

changing just your diff back is full of fail, will make more noise but the main restriction is the factory dump

Karina, the answers to all your questions are here

3" Turbo back exhaust.

That is all.

Will run slightly rich, so a retune would be your best insurance. But in my opinion for just an exhaust on a street car it isn't needed.
