You know what a mm does to some high tech missile component? It's like a tiny $14,000.00 part worth junk because it broke out in a millionth of an inch say, let alone a mm or two. So, did the square times bore square off by 2 or 4 mm say?
Something like 2 mm is X and another 2 mm is Y? So now you grab your '06/08 header you know fits from 2006 to 2011. Then, you sneak up on that 1441cc R with a 1352cc size pipe.
So now you know about this stinking mm kind of fit is no fit at all. You can look at that first gen set from the factory fit to the after market fit and fit all day long is the '06 to '11 First-Gen. If a pipe of said years [f-g] are involved to fit an R? I can say how those pipes will fit in spanish... "No Way Hose Say" is the answer.
Fit only First-Gen 14 to 14. Forget any 14 fitting an R, be it stock or aftermarket. Here are the 2 questions you place into the guillotine. This cuts you off at the pass no matter how you try getting there.
First X to Y:
I have 4 port holes and 2 crossover pipes. Say I could use a spreader/collapser kind of idea to reline the header to port? Okay, who do I cause stress to? How far out or in do I mickey each header pipe? Bingo, it's in is a 1/4 of the battle to X the 4 tubes.
Now I'm here at the sump cover and Y do you think I would not have trouble here if growth is the expansion-x and y-height is next, as you spread a curve away from the Y is the growth of the 2 mm is that long rod? Or was it 4 mm?
Second X to Y:
I'm at the end of the R's header. Since I can't tell you if the first Y would have banged into the lower part of the engine, let alone that I couldn't X: get it on the 1441 head. Nor would I attempt to change that much fit to finish off a smaller header pipe diameter too. I think I had the '08 header? If I recall, the R's pipe diameter is a touch larger, but guess who doesn't have a honeycomb inside the end of the header? The 1441's pipe. So with the ports not fitting, the no brainer was the 1441 header goes right back on.
I now grab the straight tubed stainless steel [f-g] muffler, weight that against the triangle black coated R type muffler. Find out they are pretty close in weight. So here is part X I know about, but have no clue about Y at the hanger end off the passenger peg mount? As I try to fit a well worn, but tight fitting mid pipe gasket over the 1441 header, I now begin to set a new indent into the gasket. In other words, this is where X does not fit: header end to mid pipe end.
The Y part is to imagine you standing over the muffler hanger point that is welded to the muffler itself. That is where the position of Y is the passenger peg/slash/muffler hanger point? To conclude: I could not get either to fit right on as if it would bolt or slip on either engine or pipe combo. I think we walked into Second-Gen fit to fit is the new animal of 'parts is parts.'
As I recall where Brock would post over at the pond, this being, before I gave fish his own fishslap for not listing to wee or the hand, and especially NOLTT, was how I tried to push the gun away from his foot but too late LOL! So anyway, someone chimes in with the first year R, Brock sends out a 1352 fit. The chime back in says she no fits. Brock modifies some in hose fix at the pipe bender's ear, meaning, Brock chimes in with that call to Hindle.
Right, Brock? Or ask him. I'm just assuming the header pipes needed a tiny tweak at X. Being that Brocks header to mid is going to fit, so Y is out of the picture this way. As for slips, 'Onlyour hairdresser (Brock) knows for sure.'
