Does putting an exhaust and/or headers on a bike damage the engine over time?

Question

if so what else can you do to increase horsepower and or torque without harming engine?

for fuel injected motorcycles only

Answer 1

Worst case an aftermarket exhaust will lean the mixture and that can cause it to run hot and burn the valves, the mixture should be adjusted to compensate. Most pipes are now designed to bolt on and work with no adjustment necessary. Note: The oem pipe is very tuff! it will out last most aftermarket pipes 4x. An increase in horsepower will always stress the engine more then less power...

Answer 2

short answer is not any. you ought to use the SILENCER yet not the HEADER from a 4t on a 2t, yet you will prefer to pop it open and wrap the baffle tube with packing like a 2 stroke silencer, maximum 4 strokes don t have packing as they don t might desire to capture unburnt oil in the gasoline and don't relies upon on backpressure as plenty. The header on a 4 stroke is a right this moment pipe because of the presence of exhaust valves, the two stroke has a unfold chamber somewhat, so this is significant the pipe be pressurized in case you prefer to have a powerband. It s all based on the suited backpressure.

Answer 3

adding a new exhaust and a high volume air cleaner on a bike is a great way to pick up horse power and torque. But, the addition makes the motor run leaner, this causes excessive heat, pinging and surging in the motor and over time can cause damage. The cure to this is to re jet a carburated model to rune richer, or to have the ecm on a fuel injected bike re mapped to run richer. I just changed from stock, to python exhausts and a stafe 1 high volume air cleaner on my '07 Harley ultra glide and gained 23 horsepower and brought it up to just over 90 ft pounds of torque. I had to install a race tuner to richen up the air/fuel mix so the bike runs right.

Answer 4

I am going to have to disagree with the others here...

Performance on any internal combustion engine is inversely proportional to it's reliability (didn't you hate those expressinons in science class?)

In other words: High performance causes low reliability over time. The smaller the engine, the more pronounced this is. It is far less noticable with big motors, so it may not be an issue for you. Loud is not good, and is also referred to as "psychological horsepower". I have never seen a straight pipe or debaffled one improve performance, although tuned pipes are a different story.

Answer 5

No and with the carbs rejetted, a few extra horsepower is often the result along with a lot of extra noise. The way I look at it, you only need those extra ponies occasionally while you'll have to put up with the noise all the time. Take your choice.

Answer 6

Specifically no, but as a rule the harder you run an engine the sooner it will wear out.

Fuel injected bikes are ussually modified with a performance ECM and a like air filter

Answer 7

nope, only helps it breathe better... you can change the sproket's a few teeth to gain some additional tq & hp but will gain or loose top end and or cruising rpms may be much higher. Jetting, better air filter, are some of the simple mods unless you plan to have actual engine workdone to gain more performance

Answer 8

no it won't hurt the motor. you can also port the head or heads, re-jet the carb/re-map the ecm, slightly increase the compression. too much comp though will shorten the lifespan. of course riding it to it's full potential a lot will shorten it's life.

Answer 9

no, you need to have it tune to the pipe cause it change the specs but no damage.

Answer 10

of course just like any other vehicle.
