The Victorys are all direct injected since inception. there are no carbs to worry about. Slip ons should not affect performance since the header pipes are the same flow. Using a free flowing intake and exhaust will greatly improve performance from stock but will need the computer "flashed" with the appropriate fuel map. These flashes can be done by dealers and performance shops that work on Victory and will be included with many of the intake or exhaust sytems such as Lloydz and S&S.

You may need to adjust the timing and or air flow to your carbs as the mufflers create a mild amount of backpressure to your cylinder heads. Over all this hould not be a problem, but if you plan on keeping the bike for some time you may want to look into this. Thank you.

Drive it to a muffler shop. You won't hurt anything driving it, just your ear drums, maybe.

I have a 2006 Royal Star Tour Deluxe with a 1300 V4 engine.I would like to know if the existing stock mufflers have any kind of removable baffles or anything that could be removed to effect the sound of...


loud sound is attractive to only the rider and will attract the ire of the neighbours and the law
another point , if the manufacturers thought that a modified muffler was good for the engine , the loud mufflers would be already fitted but as the design of the mufflers also includes economy and engine life that means that a balance of economy , engine reliability and noise is struck in the factory

Would after market slip on exhaust affect engine compression of zx10r? What is the best after market exhaust slip oni can to use that would have no effect at all on the power of the zx10r? Are there any...


As long as you get a muffler that is comparable to a stock muffler then it will have no effect on the performance. Most aftermarket companies make stock mufflers that would fit your bike though it would likely be cheaper to just replace them with stock kawasaki pipes.
As to replacing them, using an impact wrench will make removal easier and be sure to use a new clamp even if the old one looks good

Will taking the baffles out of my 2007 Harley Davidson Sportster effect the engines performance any?


A motorcycle engine is a finely tuned system. If you change anything on the system it will effect everything else in the system. For instance, if you remove the baffles from your mufflers, it may cause the engine to run lean. You may have to rejet the carb if you do this. You might want to check you state laws as well. In some states (or countries) if you remove the baffles it's against the law. Personally, I'd much rather replace the original mufflers with a set of high performance "slip on" mufflers. The engine needs a little backpressure to run correctly. If you remove the baffles, you may not have enough backpressure on the exhaust system and this can cause a "dead spot" around 55 to 60 mph. The bike's throttle response will be less than normal.

Good Luck

I have a 2010 harley 1200 custom sporster,if i put different slip -on mufflers on would hurt the engine if i don't change anything else


If you replace with street legal mufflers then it is unlikely that you will have to make any other changes !
Go by the silencer manufacturers recommendation

I have a new 2010 wide glide i whount to remove baffles on stock pipes will this hurt bike? or due i have to change complet exhaust and intake?


Any change or modification to any of your vehicles systems can effect your bikes factory warranty! Removing the baffles from the existing mufflers is possible with the proper tools but I think that the internal catalytic converters will prevent this. Changing the entire exhaust or just the mufflers should require the addition of a electronic "fueler" to ensure optimum operation as your bike is delivered to the showroom from H-D running lean thanks to the EPA. For the DIYer I suggest looking at www.vanceandhines.com for exhaust options and accessories.

I was wanting to find out if i took off my stock slip on mufflers if it will hurt the engine in any or anything else


Greeting!

The answer is yes, and no... provided if you replace the stock mufflers with replacements that provide the same amount of backpressure, there should be no problems. However, if the replacements do not provide enoughbackpressure, or too much, the bike's spark computer may need a software upgrade in oder to compensate.
