You should take your vehicle to the mechanic if it is letting power and exhaust popping.
The letting pf power and popping of the social in the BMW 318 series should be taken to a mechanic ASAP.
If your BMW 318 series is letting power and the passage of the exhaust it is important that you take it to the mechanic ASAP.
The popping from the exhaust and the lack of power sounds like there is something in the timing. Most likely the timing chain is worn and needs replacing.
A slip on exhaust will give a dirt bike more power. A full exhaust setup will give you even more power than a slip on.
It depends on your ATV exhaust size height and location so i really couldn't show you how but if you don't want a cheap homemade one just go to hmf exhaust .com and look at the swamp series pipes which can attach there snorkels for more power and water protectection.
converter stopped up
In a four-stroke engine, both the intake and exhaust valves are closed during the power stroke, allowing for maximum pressure to build from the combustion of the air-fuel mixture. Similarly, during the exhaust stroke, both valves are also closed momentarily after the power stroke until the piston moves up to expel the exhaust gases. However, the intake valve opens before the power stroke begins, and the exhaust valve opens at the end of the power stroke to facilitate the exhaust process. Thus, while both valves are closed during the power and exhaust strokes themselves, they open at specific times in the cycle.
Intake compression ***** POWER**** exhaust
It sounds like your catalytic converter is clogged up and needs to be replaced i had same problem had no horse power to make it up a hill and exhaust would get cherry red.
intake compression power exhaust
It' won't give you any real advantage over the stock exhaust, but it won't decrease your power.
It's a turbine mounted in the exhaust manifold to give more power and smoother running to the engine.
