It does not hurt an engine to run it with no exhaust muffler
you may burn up the exhaust valve.i would not do it.
If you run the engine without pipes , you will inevitably start a fire under the hood from the flames shooting out of the exhaust ports
Exhause leak? Bad Muffler? Leaking or cracked exhaust manifold? Bad EGR valve?
Without the exhaust back pressure, the engine could run a little richer. You may need to readjust the carbs to get the bike to run smoother.
you need to buy what they call a tuner muffler. They run from $129.99 and up.
On a car it is the tube that takes a v-8's 2 exhaust headers and combines them into a a single exhaust to run thru 1 muffler.
yes you can BUT it has to be a larger pipe to get the turbo sound out of it
Any thing but stock, Look into getting a 5" from the turbo back with a no backflow muffler. You may get a check engine light permanently on but the truck will run much better.
Any engine needs back pressure to run efficiently. That is what the mufflers do, they create back pressure. So, by removing the muffler(s), you have stopped the back pressure, which in turn causes the engine not to run efficiently.
Your engine is most likely overfilled with oil. Check your oil and make sure it isn't overfilled. However a little oil coming out the exhaust isn't gonna hurt anything, your just gonna waste a heak of a lot of oil
The muffler makes your car run quiet
If ONLY the muffler is missing from the rear of the car, and the rest of the exhaust system is intact, then the only damage will be to your hearing, and your wallet in the form of a ticket for defective equipment if you drive it on the street like that. However, I would NOT recommend running it for extended periods like that, as the engine is designed to run with a certain amount of backpressure, and with the muffler gone you are de-tuning your exhaust system and lowering performance. It's not like the old days where running open headers gave your car a power boost. Also you could be getting exhaust in the car itself as the pipe is open before the exhaust exits out from under the car.
