Will a GST Greddy SP catback fit on my 2g RS?

[earthwonder83]

I've got a great deal on one, but it was for the GST. Will it bolt right into my RS w/o problems? I know that the GST muffler would fit, but what about this?

I'm most certain it will bolt right up, but how much bigger is the piping? I know the Greddy Evo is 2 different sizes from N/T to Turbo. You wouldn't want something to big because you will lose serious power.

60mm, the n/t one is 50mm. Does the size matter?

Ask her

Yes it will matter, if you were to put a 3" exhaust on an N/T you would lose basically all performance. You need to stick with something that's more compatable with your car. I wouldn't want you to waste your money for something you might not end up liking.

So I'll lose low end power, what about high end power? Will that increase or stay the same or dip too.
