I found a place that sells both the MX and PE for NA FCs. I was wondering which one is better? They are on discount too, clearing stock or something.
They are selling it for around $600.

Deciding between the Hiper and these 2

 

I have the dual PE on my 89 turbo and love it. The main difference between the PE and MX is the fact that the PE hangs very low on the back of your car. My car is lowered with Eibach springs and the low point of my mufflers is only about 4" off the ground. If you want the "big *** muffler" look, then get the PE. If you want more ground clearance and less muffler canister hanging down, get the MX. PE sounds very good and not too loud on my turbo car (as compared to say....an apex N1). Both exhausts ( the PE and MX) will probably give about the same power increase. Its a matter of your personal preference. Good Luck
