I (think) I have an XR's Only header and it is extremely close to my return line, about 1/8". I want a stainless system, probably FMF, and was wondering if folks would be so kind as tell me how much clearance their various systems provide. I'm stock on the engine and would rather have a better fit over bigger or prettier. I wouldn't mind getting the old dual 600R headers they used fir a couple years and building a collector. I always thought they looked awesome.
