Looks like an HKS knockoff to me. Although, it seems to go above the suspension instead of under it like HKS' Hi-Power.
I'm going to go out on a limb and say that it should fit. The muffler certainly appears to be an appropriate size. The big issue is whether it will bolt up to the flex-pipe properly. You may need to have the flange cut off and modify the piping to bolt up.
Why would you need to modify the flange that bolts to the flexpipe???
Even if it was a Zetec exhaust it (the flange) should bolt right up to the flexpipe.
My AEM exhaust I had, which was for a Zetec, fit perfectly up to the Duratec flex pipe.
FocusSport & MBRP exhaust fit both flanges as well, I might add, so they're probably the same flange.
And the round muffler looks like it should work with a Duratec as well....it's just the 4" tip that would scare me
I'd like to know a lot more about the material that it's made from and get a close up on the welds, but it looks better than some Ebay items I have seen. The big worry is that if you do have a problem with it down the road there is no way you'll ever get taken care of like you would if you were buying it through a company like FocusSport.
Personally I think the Cosworth tip is already too large, so that one is clearly out of control.
has anyone ever tried the magnaflow kit how does it REALLY SOUND the web sites gives you a sound clip but i really cant hear it that well. dont get the ebay exhaust itll rust quick as [censored] my friend ordered one for his pontiac and within 2 month (florida) some rust was starting to show
