So I keep reading all these post about how the cat's are causing the motors to heat up too much and changing them would help with the heat. What if their just left alone. Will the bike not last as long. I haven't rode too many miles on my SG to have a problem but I plan too. I just spent a lot of money for my bike and hearing all this stuff about pipes and cats bums me out. S@#T I don't really want to spend 1500 bucks to change all this stuff. I don't care to have a loud bike but I like hearing the ones that are. BUT if it will make my bike last longer then it a no brainer. Can I change from the cat header to a not so loud exhaust and still get the heat away and better mileage? Just asking your thoughts. Mines a 2011 with the new 103 stock its fast as it is so not too worried about the speed.... OK now beat the hell out of me with your responses

Stock Pipes Leave them like they are???????

I guess the heat is subjective to you, and if you get
that hot riding or not. I put right at 15K on my '09
Ultra and just put some Monster Oval slip-ons on
her yesterday and reallylike the deep growl they put
out and sound off when you twist the throttle. I was
definately used to the stock sound and will take a bit
for me to adjust to these, (not loud just different).

Sorry, I can't think of something stupid to say.
I bought a V&H Power Dual 2-1-2 head pipe and it made a large difference in the heat on both my wife and myself.
I used the stock mufflers back and it made a little difference in the loudness/tone of the exhaust.
I lucked into a near new V&H for $200 on eeebbaayy.
Good Luck,

I just did 3500 miles in some heat 100+ temps with a 2010 Streetglide stock head pipe nightstick muffler. Its hot but you can do it if you stretch your legs out to highway pegs your leg get HOT real fast. If you just have your feet on the floor boards its not as hot and at times cant tell. Just sitting in traffic or going slow its HOT.
I think you need to put some miles on it. Ride it and find out what is going to work out for you.
Right now I put a fuel moto head pipe on with nightstick muffler it was louder than I want been there done that loud bike thing I removed 2 disks from muffler and seems pretty good little louder than it was but not to bad. Yes way cooler, I will figure out what I want for a muffler later I have bigger things I want to do with engine cams, etc.

Like you, I'm only worried about longetivity. If the motor is going to last substantially longer with no catalyst and it tuned much richer, I'll yank it off. If the wear difference won't be appreciable, I'm leaving it the way it is. My 103" sounds decent stock, I'm going to put V&H fishtails on it, but leaving the cat unless I see data indicating the motor will grenade unless I change the headpipe.
The only issue I can think of is additional heat in the oil. I'd like to hear from a tech that services police bikes. How are they holding up, with the cat?

The bike will suffer no ill effects from having the catalyst on it.
The catalytic converter is an "afterburner" of sorts to reduce emissions.
The standard cat on most car applications can run an internal temp of nearly 1700 F.
The stock engine doesn't care one way or another if it's there or not.
The transmission (right side) can handle the outside temps , but it would be nicer if it wasn't there.
Your leg will feel it in slow moving traffic , not so bad at highway speeds.
Removing it can improve exhaust flow significantly , and make more power.
If it runs good for you in it's stock form , leave it.
I like the sound of mine stock , and it's different than most bikes because it is stock.
I don't have a converter in mine because it's an 09 federal bike , but I might remove it if I had heat issues on a later model bike.
If you don't mind the heat , the bike won't either.

True, for extended periods towing or at WOT on a passenger car a catalyst can run up to 1650 or so. They usually are damaged for any significant time above that. Riding around town I know mine is nowhere near that temperature, though.
I do think it has the potential to add additional heat to the trans and oil. Would be nice to see what oil temps are on a 09 federal bike and a 2010 bike, with the stock tune, over a similar drive cycle.
I'm not worried about the 5hp it's robbing, if I wanted a genuinely fast bike I wouldn't have bought something that weighs 800 pounds.

If possible you should ride on the same model with a pipe upgrade and see what you think. I'm in So Cal and the heat and cagers can be cruel. I upgraded my pipes to enhance my safety, reduce the bike heat and add some power. It was worth the cost. I'm not sure if the upgrade helps the engine any, but it helps me alot.
