Science Abuse Posted February 20, 2012 Report Share Posted February 20, 2012 Did they change for the supercharged versions? Basically, will adding 04 cobra manifolds to a 96'ish motor be of any benefit? Secondly, what are these? FRPP extra short shorties? http://www.ebay.com/itm/03-04-Mustang-Cobra-Mach-1-DOHC-4-6L-Exhaust-Manifold-/140693470985?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item20c1fbff09 Quote Link to comment Share on other sites More sharing options...
schmuckingham Posted February 20, 2012 Report Share Posted February 20, 2012 Exhaust flanges were different between the 4V heads, I think it depends on if they are C or B heads. Dont quote me on that though Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted February 21, 2012 Author Report Share Posted February 21, 2012 I'm seeing some classifieds for headers that span 96-04, all of which long tubes which I'm sure isn't a coincidence. But that's taking the used-parts owners on their word. Quote Link to comment Share on other sites More sharing options...
Buckeye1647545503 Posted February 21, 2012 Report Share Posted February 21, 2012 The exhaust side is the same on all 4v headers but the issue becomes the steering shaft. the difference b and c heads is on the intakes Quote Link to comment Share on other sites More sharing options...
Buckeye1647545503 Posted February 21, 2012 Report Share Posted February 21, 2012 03-04 manifolds are a upgrade but aren't a bolt on Quote Link to comment Share on other sites More sharing options...
On3Performance Posted February 21, 2012 Report Share Posted February 21, 2012 The exhaust ports on the b and c heads are not identical. My 04 heads on my notch are larger and more rectangular compared to the heads on my 99. I cant see it being worth the hassle upgrading to the 03/04's. If your going to do anything, I'd do a set of shorties or long tubes if you have the cash Quote Link to comment Share on other sites More sharing options...

I'm looking for something cheap to cut up. Quote Link to comment Share on other sites More sharing options...
