They will probably smoke for about 100 miles or so. they will also shrink. Caution...... depending on the brand you put on, they may even start to stink a bit, especially if they get wet.. this happened to a friend of mine. But, I have no idea what type he put on.. Im assuming he put on the cheapest he could find.. So it may be different in your application.

Harley-Davidson exhaust pipes too hot(low rider 2016 s).

Hi, Lamont some brands of motorcycles will have exhaust discoloration right out of the gate when brand new due to engine design and the quality of the chrome plating. These bikes will also have chrome heat shields to prevent burns from accidental contact and hide ugly exhaust discoloration. Some manufacturers go as far as having heat shields on mufflers. If you purchased a brand new set of chrome aftermarket mufflers or a complete exhaust system only to find excessive bluing on the headers and golden and sometimes blue areas on the mufflers appear after a few hundred or so miles of riding your first impression is your exhaust is running too hot which must mean so is your engine. Wrong! exhaust discolour is caused by 3 different things.
1. Poor quality chrome plating, usually dictated by the price of the part.
2. Retarded ignition or cam timing caused by improper installation or a faulty CPS, CKP, MAF, MAP sensor.
3. Mufflers discoloration is caused by an excessively rich fuel condition.

Extreme heat coming from the exhaust between seat and body from my 2013 canAm spider RT limited

There are several things you can do to reduce heat on a Can-Am Spyder.

1- Remove the plastic 'Splash Panels' under the frame below the motor. These were added NOT to keep water and debris off the motor, but to reduce noise to pass EPA noise standards. Removing these panels will not hurt anything and allows hot air to flow out and cool air to flow into the engine compartment.

2- Wrap the exhaust with exhaust wrap (found at any auto parts store). Start as far back on the 2 exhaust pipes as possible wrapping towards the front. Wrap all the way to the head on each pipe. 1" exhaust wrap goes around bends better, 2" takes less time. Overlap each wrap by 1/2 of the width of the material.

3- Adding a fuel management system (Two-Brothers Juice Box Pro or Power Commander system) will allow you to increase the fuel mixture to ideal levels. The Spyder runs very lean from the factory creating additional heat.

Where to fill transfer case

HI. On the strat the fill plug is just behind the rear exhaust pipe about one inch or so to the rear. You need to loosen the front exhaust header nuts (don\'t remove 17 ft. lbs. ) remove the rear header nuts (these are allen style 14 ft. lbs.) pull the rear header out of the exhaust port. Use a torque wrench or they will leak. Now you have enough room to install the allen wrench into the fill plug. This plug is about 1 1/2 in diameter. It is a big pain to do. Don\'t loose the exhaust gaskets or just buy new. They are about $12 each. I have reused them just a couple times then install new.

08, 1125r...Just bought it. On my first ride i noticed gas drips from tube on the back of bike opposite side from exhaust. I assume this is an overflow tube but it drips gas for 15 minutes after every ride...

It is a known issue - you can take it into Harley but last guy I knew with that issue - they had the bike for a month and gave it back to him no changes said they couldn't replicate the issue. The gastank on the bike is getting hot causing the gas to evaporate and create pressure inside the tank - hence the gas dripping out of the pressure vent. Some guys have put some heat insulation in between the side of the tank/frame and where the headers get close. Other guys just wrapped their headers with thermo wrap - seems to help tons.

I have an '06 Vstar 1100 classic and i bought new exhaust pipes for it. How do i get the stock muffler off the headers?

often the sealant used is the problem,undo and remove the bolt/s holding the muffler to the swing arm there will be a clamp of some sort to tighen the muffler to the header undo this and you may need to lightly prise the header pipe open ,normally there are slots in this pipe to allow it to compress onto the header or it could be other way round where slots are on the muffler pipe. you may need to lightly tap these pipes away from each other with a block of wood and a hammer. in some cases they will be very tight together. in the past i have had to run the bike to get the exhaust hot and then cool down with water ONE of the sections to shrink it. BE CAREFULL NOT TO BURN YOURSELF. they should seperate fairly easy then.

Heat questions

The shock would get just as hot without the exhaust being next to it. The amount of heat generated by the thousands of up/down cycles a shock goes through, especially at racing speeds, is higher than the heat transferred from the pipe being next to it.
