If you're looking at a chinese exhaust system, something tells me you're more into it for the noise it makes than any significant power gains/weight reduction. And if that IS all you care about, go for it. If not, I'd invest some more money into it.

Tyga systems are cheap for a full exhaust ($400) and netted my bike 31 HP after an air filter and jetting.

@splitfire - there are 3 main goals that riders are trying to accomplish when buying exhausts systems; looks cool, sounds cool/loud, improves the performance of the bike. Some even combo those goals. Which goal(s) are you trying to reach? You can get decent mufflers (cans/slipons) for lower dollar amounts, but once you get into full systems (headers, midpipe & muffler) the price goes up pretty quick. I was partial to areap for my exhaust needs; performance, mounting and sound db requirements being on the lower end of the spectrum. Have a look in the racers areas on different or even a local forums. Racers take off those fancy slipons and sell them for cheap all the time and the new race season for many has just started. So that means somewhere out there, there are some slipons just taking up space in a racers garage. The price of new though... $100 isn't going to buy you much exhaust, maybe an extra loud slipon. Anything else is going to cost a bit more. The china cans are like winning the lotto, it's rare... but sometimes you get a winner but it's highly unlikely from the longevity perspective.

I put one on my Kat 600. I will agree, it's good quality for the price.

FWIW I put a Danmoto slip-on on my 2012. Sounded and looked really good (IMO) and was ~$100 at the time. So if its sound and looks you're going for that's my

thank you guys. i think i will pass for now. coz if am going to change my muffler to an aftermarket i have to do rejet too which i dont want to do. dont want to have problems with back pressure, backfire and mileage. i'll just stay stock. If there is a muffler that doesnt require a rejet and has a good price around $100 i'll do it.

A good example of that is the Area P exhaust that Csmith mentioned. Area P sells two different length mufflers to go with their race system, a 12" "Shorty" muffler and an 18" muffler. Can you tell me which one makes more power and why? It's the 18" one. That is because exhaust systems perform better when the exhaust gases expand more gradually toward the exit. (BTW, that is why there are megaphone exhaust systems.) The shorter muffler basically means that there is less distance for the exhaust pressure to dissipate into the packing material whereas the longer muffler allows for a more gradual dissipation of the pressure (More like a longer megaphone.) Look at the exhaust systems on Moto3 bikes. They have an extremely long and gradual taper to extract the maximum possible power out of the engines. They are making at least 55hp out of the 250cc single cylinder Moto3 engines now and you can bet that every bit of the exhaust system matters in making that kind of power.

The Danmoto needed the needles shimmed.
Also the 2 Brothers that was on my 300 needed a power commander and the ones we put on my pregen needed carbs jetted. All slip-ons.

No muffler requires a rejet. What I said is correct. He has mentioned an area p exhaust system... What he mentioned was racers buy bikes with a slip on exhaust... Then they buy a fancy new exhaust system for the race season... Now the "useless" and not requiring rejet, slipon MUFFLER is in the closet collecting dust... I am not wrong, you can buy any MUFFLER you want, you will not require a rejet on a 250. That is the point of a slip on, you slip it on, and go. I said you need to change the EXHAUST PIPING to require a rejet... This is still true... |

I heard I need to change my fuel delivery setup, too — true?
The answer depends on a lot of things. What kind of bike you have, what kind of exhaust you have, and how you want your bike to behave! As a general rule, most slip-on or “muffler-only” exhaust systems do not require alterations in the fuel delivery, but even a bone-stock factory motorcycle will benefit from fuel management changes. -Revzilla It's a general rule... Unless your engine can push more gas out or take more air in (for example WIDER PIPING) you should NOT require changes to fuel management. You may still want to do it, but you do not HAVE TO do it. Anybody who says you must, is frankly, full of crap. The reason most people require shimming is from removing the snorkel, or changing to K&N high flow filter, PLUS they install a slip on exhaust. |

It's semantics.
You're arguing for the sake of arguing.

I would rejet it even with the stock exhaust. The bikes come lean from the factory to pass emissions and even in stock form will benefit from a jet kit and needles. Any reduction in exhaust back pressure will only make the bike run leaner.
