I've seen some mention here and there about the OBX headers fitting the 3.5RL
They're inexpensive so I'd like to grab a set, but any confirmation about suitability/modifications? The gaskets and bolt patterns appear the same. Honestly I have to admit I'm not sure what the differences are physically between the C32A and the C35A.
I would prefer someone to chime in that has already done it.
I know the primary tubes are 1-1/4" does anybody know the pipe diameter of the y-pipe and b-pipe? The math says the y-pipe diameter should be just under 2.25" so I would be happy to see that being so.
I had wondered why everybody complained about the y-pipe, but from looking at pictures, it's nasty. I read that the Y-pipe necks down to 2.25" but from the looks of the B-pipe and the cat-flange a 2.5" y and b pipe combo looks simple enough. Of course I'm not into 'simple.'
I'd like to hack off the Y pipe collector and flange and replace it with a 2.75" SS V-band Clamp.
From my personal battles with exhaust systems, I'd really like to run 2.75" at the y-pipe merge, but this really is depending on the initial pipe diameters and clearance. I would of course try to improve the 'y'ness of the y-pipe. I'd then put a smooth transition to 2.5" pipe.
This is all pure theory, since I don't have hard facts at the moment...after I get some facts, I'll make some choices. I'll probably plan to do a few of 'em.
