- Bigger jets allow more fuel and smaller jets allow less. The rejetting process figures out which size jets is needed to keep an engine running with the right mixture. Too little fuel and the engine may starve or overheat at high RPMs.Too much fuel and the engine could flood and bog out.hares & Saves. Save. Replacing an exhaust with a carburetor-type engine is more than just bolting on a new pipe. Whether it’s a car or motorcycle or scooter, you are likely going to need to make sure your carburetor is running with the correct jetting for the new exhaust.

- You will never pass emissions. But if you don't have emissions tests, removing the catalytic converter will increase flow of exhaust from your engine, allowing the engine to run more efficiently. This means more power, and since the weight doesn't change, better fuel economy (usually).

I have a 2007 harley davidson if i change the exaust will it void the warranty? If you have an injected model, then you need a power commander or fuel pak PC unit, also you will need to change the air filter to a mass flow, like a K&N air filter, then change the exhaust. They recommend running it on a dyno. If you do this it will keep the warranty in tact.

- However, you should not have to rejet after a slip-on. It will probably help w/power, throttle response, and the power curve, but it won't be necessary. I didn't rejet after my full exhaust and it was more than serviceable. It just depends on what you want from the bike, and how much you want to spend.

Understanding Diesel Exhaust Fluid - Basic Training Understanding Diesel Exhaust Fluid - Basic Training. Demystifying the Selective Catalytic Reduction System. Emissions regulations have been on the minds of diesel pickup owners, prospective owners, and professional over-the-road drivers for some time now. It began with the implementation of exhaust gas recirculation (EGR) systems, then progressed to the diesel particulate filter (DPF), and now the buzz is around selective catalytic reduction (SCR). Selective catalytic reduction systems use a consumable diesel exhaust fluid (DEF) in conjunction with a catalyst to reduce nitrous oxide (NOx) emissions. Because the fluid is consumed during the system’s normal operation, it requires the vehicles owner to not only monitor the fluids level but also refill it when it’s been used up.

- #21 Backfiring On Deceleration. Hello Group, One of the most asked questions pertaing to the Honda Elite CH 150/250 and CN 250 Helix involves a backfire through the exhaust on sudden deceleration. An engine is not supposed to backfire and, when it is persistent, It could be harmful to the engine.

New Exhausts for New Indian Scout Performance gains are nice, but this 2-into-1 looks great too. The new header pipes create a cleaner profile compared to the stock set. Trask definitely took a more streamlined approach by shortening the overall system and because it is a 2-into-1, the system is much more confined.f you don’t feel the need to replace the whole system and still want the look of a 2-into-2 system, Trask has just the slip-ons available as well. You will still see performance gains throughout the entire power-band and also experience a better sound from the slip-ons vs. the stock mufflers.

- The second valve, TAD (Thermactor Air Diverter valve or AM2 valve) directs it to the heads or the catalytic converters. Check valves located after the TAB & TAD solenoids prevent hot exhaust gases from damaging the control valves or pump in case of a backfire.he Thermactor air pump draws air from an inlet filter in the front of the pump. The smog pump puts air into the heads when the engine is cold and then into the catalytic converters when it is warm. The Thermactor control valves serve to direct the flow.

- To Change or Not to Change. If you’re just swapping the exhaust with a new one of the same type, there’s probably no need to rejet your carburetor at all. Where it becomes an issue is when you are installing a stronger or tuned exhaust.hares & Saves. Save. Replacing an exhaust with a carburetor-type engine is more than just bolting on a new pipe. Whether it’s a car or motorcycle or scooter, you are likely going to need to make sure your carburetor is running with the correct jetting for the new exhaust.

Remove the EGR Valve â Bad for Your Diesel Engine? The EGR system does not pass the exhaust back through the air filter because there is too much soot which would clog the filter in a matter of minutes. So if the EGR process is too dirty to pass the exhaust through a filter, think of all that black soot that is going directly into the engine. Third, because exhaust is hot, it must first be cooled prior to re-mixing it with new air. Piping 700°F gasses into the engine is a recipe for disaster.

Tips To Modifying Your Mustang - Starting Fast For the 4.6 crowd, exhaust is not quite as important because of the physical sizes of the large engine and tight chassis. To put it bluntly, if a short-tube header fits in a 4.6 Mustang GT, the header doesn't work (that gem came from a Ford engineer charged with developing Mustang exhaust, so he should know). To make a 4.6 exhaust work-GT or Cobra-a long-tube, four-into-one header is required.

High Flow Catalytic Converters: How They Increase Engine Performance and Why You Should Get One Waste gasses from the motor contain harmful smog chemicals such as hydrocarbons, carbon monoxide and nitrogen oxides. It is the catalytic converter’s job to reduce these harmful emissions as much as possible in order to protect the air we breathe.The way that the catalytic converter functions is simple. It forces the exhaust gasses to come in contact with a chemical catalyst, in this case the metals platinum or palladium.The catalyst causes the gasses to quickly degrade into less harmful substances, like carbon dioxide and water.aste gasses from the motor contain harmful smog chemicals such as hydrocarbons, carbon monoxide and nitrogen oxides. It is the catalytic converter’s job to reduce these harmful emissions as much as possible in order to protect the air we breathe.

- The resonator is used to provide the sound the maker of the car wants as well as helping performance in a specific RPM range. So by removing it, you may get the sound you want at the expense of performance.The exhaust system on a car can be tuned just like the pipes of a organ.It has to do with resonance, volume and length. It is one of many details that auto engineers make big bucks figuring out. like loud. Anyways there is a long resonator right after my catalytic converter. My friend says it's for both noise and emission... show more I'm redoing my exhaust system for my 1996 Mazda MX-6. I just want to make it a straight pipe with a glass pack (to tone it) instead of muffler to make it sound loud.

- Rejetting is changing the carb./fueling set-up on the bike: fuel/air mix screw, needles, and jets. It's just the way the bike determines how much fuel to flow depending on set-up, throttle input, etc. A mechanic will know how to handle it. However, you should not have to rejet after a slip-on.

- Diesel Particulate filters (DPF) or 'traps' do just that, they catch bits of soot in the exhaust. As with any filter they have to be emptied regularly to maintain performance.For a DPF this process is called 'regeneration' – the collected soot is burnt off at high temperature to leave only a tiny ash residue.iesel Particulate filters (DPF) or 'traps' do just that, they catch bits of soot in the exhaust.

- Harley-Davidson engineers know which header pipes work best in terms of deminsions, so most of the time a set of slip-on mufflers will give you a good performance boost, without the added expense of changing the header pipes.Here's a look at different types of Harley-Davidson exhaust.TRUE DUALS.xhaust system design has a big impact on engine performance. Header pipe diameter, bend radius, pipe length, muffler volume and design of the baffle effect performance. If the pipe is too long or too short or if the diameter is too big or too small, performance will suffer.

- A smooth and unrestrictive exhaust path after the header is key to FA20 engine power and performance. Free up your Scion FR-S or Subaru BRZ exhaust flow with smooth bends and larger diameter tubing - the PERRIN Performance overpipe increases flow without adversely effecting overall exhaust velocity.

- I've heard you need to rejet the carbs when you change the exhaust but I wonder why. After all, the exhaust is just exhaust. I can see rejetting if you change air filters, air box or other things that mix fuel and air.But I can't quite see why you need to do anything if you're just changing the exhaust.(I do street riding and commuting, no racing).To me its like requiring you to change the faucet if you change the drain in a sink. can see rejetting if you change air filters, air box or other things that mix fuel and air.
