they bolt up to any -4. but I believe these will need a 1.7/1.8 Muffler... the 2.0 version is straight at the end.
if they are SS they will have the same Inter-Diameter pipes, regardless.
btw - I believe that the 2.0s are a bit larger diameter pipes, ergo better exhaust flow.
Thanx for the clarification & Rique too!
