People, this is an '04. It's got the Y pipe off the rear jug. This is a completely normal temperature condition for this header. The exhaust varies between a 2 into 1 system and a 2 into 2 automatically based on speed and draw. It's the best exhaust Harley ever made in my opinion, and if Rinehart or Vance and Hines made it people would praise it all day long. I wish I could put mine back on but my T-Max won't read the rear O2 sensor correctly because it's on the 2 into 1 side of the Y and when the exhaust starts pulling through the clutch side it reads a lean condition and richens the rear cylinder.

 

Loc Tite ... I mentioned that earlier ... I guess it just hasn't sank in yet. :>)

 

The H pipe coming out of the rear cylinder was subject to cracking after a time. Might want to check to see if yours is cracked.

 

I saw it Larry but there was too much b.s. to wade through to pull your quote.

 

Thanks for the feedback. Correct. 2004 with Y behind 2nd jug. Just never noticed left exhaust not getting warm / hot before adding new exhaust. I have plenty of heat coming out of the 2nd jug where the Y begins so I assume that since the new exhaust do not have back plates and have a real open design, heat is not building up because of less restriction. Bike is running fine, no error codes, check engine lights, etc. Just paranoia on my side. Thanks for everyone who posted.

 

okay, so spoke with powercommander and they sent me a pretty "hot" map, in my opinion. Loaded it and went for 500 mile So new full boar slip ons with cold air blowing out of left exhaust slip on. Talked to power commander and they sent new map for PCIII. Looked
A little "hot" to me, but loaded it and went on 500 mile trip over the weekend. Bike sounded like it was misfiring or back firing here and there during crusing speeds but was not lacking anywhere through the throttle position or RPM range. This was Sunday. Had been talking to power commander already about upgrade to PCV (undecided on autotune). Monday, I start bike and the dreaded check engine light comes on for 4-5 seconds and goes off. Run Diag code and get p113 (open/high temp sensor). It appears that my brand new slip on the left side is already having slight "bluing". Being the genius I am, I decided to clear code and hook PCIII and ride it to see if I heard any backfiring or if it would throw another code. I've had the flu and wasn't thinking clearly and let one of the plastic ends of the power commander touch the right exhaust and you guess it, burned it badly, not to mention "krud" all over my pipes. The bike has k/n open air filter, screaming eagle upgraded hydraulic billet cam plate, Andrews 21 cams and full boar exhaust 2.5" baffles. Now that the power commander is off of the bike, it will start and idle real low and die if I don't give it throttle, I assume to low RPMs. I assume with my setup, this should be expected. The full boar 2.5 allows a LOT of air through. I'm scared to get out and ride, as I don't want to mess anything up (if I haven't already). Should I assume the low idle is normal and most likely starving for fuel? Also, I've ready many people say it was wiring, not the sensor that was bad. Lastly, any feedback on PCV with or without autotune would be appreciated. Still "baffled" (pun intended) as to why left pipe is blowing cold air and pipe is cold to touch after riding hard for 250
Miles. I know that my other exhaust (factory) would get so hot, you wouldn't dare touch it. Is the fact the new slip ons are SO open as to why no heat on left side exhaust? Thanks to all that respond. I'm in Arkansas and it's riding weather as "I gently weep with my Harley" in the garage at the house.

 

If the bike ran right before messing with new maps and a "cold" muffler was the only concern, I think that this becomes a made up problem due to overthinking.
Listen to the posts of Loc Tite and Uncle Larry.

 

Sorry for having too much bs to wade through. To me, information is power. Came to this forum seeing advice. I took the left exhaust pipe off and the air coming out of the rear cylinder is "cool". Not hot. Not warm. And with it throwing a P113 code, I feel like it is not coincidence. The reason people come to these forums is we all have one thing in common and that's the love of riding and our bikes. Shouldn't be made to feel like the teacher is slapping your hand and telling you to shut up and listen. I've ordered a PCV and taking to shop. I will repost the outcome.

 

Call me simplistic, but if the air coming out of the rear cylinder is cool, then the rear cylinder is not firing.

 

Finally someone that realizes motors create heat!! If the rear cylinder has a pipe coming directly off of it, and yes...it is a "y" where gases are pushed to both exhaust slipons, you should not be able to ride 100 miles and literally grab EITHER pipe. When you can literally wrap your hand around the left slip on where it connects to the head pipe and hold it until you get tired of holding it, not because it's hot AND it is blowing cool air out of the head pipe, something is not right. The quandary here is the head pipe is hot on the left side for the first 12-13 inches (right before the head pipe bends back to the slip on.....but.....when you take the slip on off of the left side, it is blowing cool air right out of the head pipe so my theory is that since the rear cylinder is a "y", the heat that is felt for the 12-13 inches on the left side head pipe is actual heat that is being pulled over from the right side because they are connected at the cylinder with a "y". At this point....it goes to the stealership. Thanks, Dave!!
