Anytime the factory crossover is used you'll have a very hot butt with the rear cylinder temps running considerably higher than the front.

.................................................................................. [highlight]Do people who have only installed slip-ons w/ stock headpipes (with A/C and ECM mods) also have heat issues?[/highlight] If so, TD's seem to make sense. I'd be interested to hear about the heat issue specific to this. With only these 2 things done are TD headpipes really necessary? Great, more questions! Thanks.

Hoist,

First, no matter what exhaust system you use the rear jug will run hotter than the front, due to air flow.

I'm sure there are those who know more about exhaust than I, but it was my impression that the cross-over was simply a means to allow each cylinder to make use of both mufflers, thereby reducing the resistance and improving flow. It allows us to use smallish diameter mufflers instead of one great big one (as in a 2 into 1 system).  When choosing between a 2 into 2 with crossover versus a 2 into 1, I thought it boiled down to personal preference of style more than anything else.  Can someone correct me, if I have the wrong impression on this?

True duals look great because they have no cross-over.  They also do not contaminate one cylinder's discharge with the other's intake from back pressure.  Unfortunately, there is no true dual system (that I know of) that is sold OEM on the bike, since they are too loud, not being able to utilize the cross-over to breathe into two mufflers. When I read the recent post about Harley OEM mufflers not breathing equally, it made no sense to me.  Perhaps someone here can explain if that is indeed the case, and if so, why?

I think Harley has done an incredibly good job of creating an OEM cross-over exhaust system that is of high quality construction, breathes reasonably well, and is not overly quiet.

Exhaust pipes... please try this site http://www.rbracing-rsr.com/index.htm
If you want the best performance along with good sound and quality then this is it.
I out on a LSR 2 into 1 prostock 2" c style and gained 10 hp and YES 19 ft lbs of torque..
The 1 3/4" would have produced even more torque...
I think you will be impressed with the site and the info

Thanks Mav. I've always loved their 2>1. After I burnout my Supretrapp, it's going on my Pro Street. It's nice on the Springer. But I don't want it on my touring bike. I't's too loud for all day trips. I like a dual exhaust on a dresser. Seems like I'm using V&H TD's at that. I also plan on using S&S SPO Slip-ons. Did you do aything else besides pipes? What ECM Mod? Thanks. Hoist!

A great investment for those concerned about the heat issues is the purchase of an infrared thermometer for about $70.

The really good ones that measure within a 1/2 degree of accuracy down low also can also be a lot of fun pointing at different places on a young lady's........ um......; never mind.

Man....where were you with these ideas when I needed you...... [smiley=xyxthumbs.gif]

Brian, sometimes technology truly is a wonderful thing.

I've always preferred measuring those temps manually...

I've noticed a big difference on my right leg, back of the thigh heat sensor since installing the TD RH's, and not a corresponding increase on the left...I'm sure that there is more heat ON the left side now, but my left leg does not feel any more than when the crossover was there.  Of course, it hasn't been 95 degrees lately either.
