Gutting Cats - the real facts
#31
I agree with you on this. I've been running Xied's for two year's on two different bike's. Mine is running what you see in my sig pic. I've had good result's. Plugs look great, Gas mileage average's around 45 mpg. I know it's not the perfect tune, but what is with all the change's in condition's? My cruise range is between 28 and 3200 RPM's.
And yet you defend them as something other than snake oil. They're a placebo, that's about it.

You might want to lube your muffler bearings while you're at it. They have as much of an effect on your bike as XIEDs.

So, getting back to gutless cats.........what's the difference between a gutted header pipe from a 2010 model to a cat-less pipe from a 2009 model? i realize the O2 sensors are in different locations, but is there any real difference in the shape of the pipe at the collector?

It's not a tune at all, that's the point. It's a one-size-fits-all addition of fuel to the area of the map that needs it the least. Very good for lightening your wallet (and putting money in Nightrider's accounts), doesn't do much of anything for the bike.

I never said they were a tune. They enrich the closed loop from 14.7 to 13.8
14.7 is lean and lean create's more heat right? Everybody complain's about their bike's running too lean and hot. 13.8 is about what the ECM's open loop start's at. Lot's of test and research has been done. I think Steve Mullen at niterider has a good product for folks who want to leave their harley's mostly stock, but eliminate the lean hot condition. I've looked at a lot of dyno chart's where guy's have tuner's. most of the afr's are right in line with 13.8 to 14.2
The smartass remark about greasing your muffler bearing's does as much good is uncalled for. Lot of forum member's use Niterider's Xied's with good result's.
