I have bought a greddy turbo and it comes with a downpipe, but have heard speculation that greddy downpipes only work with greddy exhaust. I was looking at getting the HKS Ti Racing or Rotary Extreme Ti Exhaust. Just want to make sure that they will fit before I blow some cash on my exhaust. Please give me feedback... Thanks

 

It should fit just fine. The exhaust only has one path to follow, so I see no reason why it shouldnt fit.
