Any suggestions on removale of Exhaust Flapper Actuator valve?
Have removed Cat on std. Header pipes (12 R/Glide) and jammed flapper thin open, but need to remove, is 1 3/4" at header and V and H muffler. Thought about cut section off and reweld new length 6", were do I get chrome section from? Should have done when removed bloody cat.Any other methods? Thanks.
new pipes lol
My stock header pipe cracked where the active exhaust valve is welded . I removed the active exhaust valve and gutted the cat while i had the header pipes removed from bike. Check out ( "my pics ), for photos of work done. Bikes is 2009 flht. I could not be happier with the results.
Get dealer to disable the active exhaust valve via the ecm so no error codes are made. If you have a more advanced tuner , you may be able to disable the valve that way. When all is done , just cable tie the cable that went to the valve out of harms way.
Grind off the flap, cut out the cat, Weld it up.
Louder and revs cleaner.
Hey there, I've seen this done somewhere here before.
I'm no performance expert, we propably need some tuning and performance experts to give their opinions . There are many riders that have removed their stock headers and replaced them with custom , (no active exhaust valve, and no cat) pipes. Doing a similar mod on "stock headers', ie, no valve and removing the cat', should give similar results. The custom pipe manufacturers may state that they will give better results on performances. The individual will have to make that decision with regard , costs, looks, and performance. Doing this mod on stock headers works for me.
With regard , can this mod do anything 'bad', in my opinion no, its been done a million times, and we would sure as hell know on forums like this if there were problems, but then again the tuning experts may have other opinions.
From my research, just be aware, what model and year your bike is before doing this mod on stock headers. My bike is a 2009 flht. The O2 sensors are located 'at the top' of the header pipes , near cylinders. 2010 and later have O2 sensors, (smaller and heated), located lower near the cat. I was confident doing this mod on my 2009 bike because , all things being equal, I would'nt have problems with so called 'cross talk' between the O2 senors, ie , tune and performance. This is another issue that the tuning experts may have other opinions
With regard dyno numbers, before and after mods, I have no info on this, but no doubt someone here will .
