Exhaust Description

	Upgrading your car, truck, or SUV's auto exhaust system is a great way to build horsepower, free up trapped torque, and improve upon anemic-sounding factory systems. The larger pipes, low-restriction mufflers, and tuned resonators of a well-designed performance exhaust system can make a world of difference on your vehicle. We have truck and auto exhaust systems from Flowmaster exhaust, Gibson exhaust, and a host of other highly-respected exhaust system manufacturers, with applications ranging from Honda Civic exhaust systems to LS1 Camaro exhaust systems. Those of you with newer vehicles are no doubt thinking, "what about emission control regulations?" The government doesn't take kindly to bypassing smog equipment, something the smart tuner keeps in the back of his or her mind whenever an upgrade is planned. Enter the cat-back exhaust system: For newer vehicles, Flowmaster exhaust, Gibson exhaust, and many of our other premium manufacturers make cat-back exhaust systems (short for catalyst-back exhaust systems) to fit your needs. These cat-back exhaust systems leave the emissions-control gear in place, but allow you to put large-diameter exhaust pipes and low-restriction performance mufflers into the system after the catalytic converter. The net result is lower auto exhaust backpressure, more horsepower, more torque, and a much hotter sound, all while staying perfectly legal.

car exhaust can linger

The daily exposure to free radicals from car exhaust, smokestacks and even your neighbors’ barbecue could be as harmful as smoking, according to a new study. Many combustion processes, such as those in a car engine, create tiny particles that may act as brewing pots and carriers for free radicals — chemicals believed to cause lung cancer and cardiovascular diseases.

The findings are from Barry Dellinger of Louisiana State University in Baton Rouge, who reported them August 17 in Philadelphia during a meeting of the American Chemical Society. Whether the exposure equates to smoking one cigarette or as many as two packs a day remains difficult to determine, he added.

His team’s lab experiments — first described in the July 1 Environmental Science & Technology — suggest that noxious chemicals form on soot nanoparticles in the still-hot residue of combustion, for example inside a car’s exhaust pipe and catalytic converter.

The chemicals are hydrocarbon-based free radicals. Similar chemicals usually degrade quickly if they float solo. But in this case, the chemicals stay attached to the nanoparticles, and they linger in the air for much longer than previously thought. “To our enormous surprise, the free radicals survive hours, days, even indefinitely,” Dellinger says.

To mimic the conditions in car exhaust as it cools, Dellinger’s team used silica particles 100 nanometers wide and coated them with copper oxide. The team then exposed the particles to a hot gas — experimenting with a range of different temperatures — containing hydrocarbons typically produced in flames. All those ingredients are common in the exhaust of motor vehicles and factories.

The researchers then examined the nanoparticles with magnetic fields tuned to identify unpaired electrons, the feature that makes free radicals highly reactive and potentially dangerous for living cells. The data showed a signature typical of free radicals and similar to that of semiquinone, a free radical found in cigarette smoke.

The free radicals, however, only showed up when the initial ingredients had been mixed together at temperatures between 200 and 600 degrees Celsius. That means free radicals are unlikely to form during the actual combustion, which takes place at higher temperatures. Instead, they would likely form once the exhaust begins to cool down.

David Pershing, a chemical engineer at the University of Utah in Salt Lake City, says the findings are potentially significant for human health.

Dellinger added that more research is needed to determine not only where someone would be exposed, but also how much the body would absorb.

The exact amount of risk the pollutants pose is hard to estimate, Dellinger said during his presentation. Air samples provided by the Electric Power Research Institute of Palo Alto, Calif., suggest that the risk could be equivalent to smoking as little as one cigarette a day or as much as more than two packs a day, he said. “It’s early in the game, and there’s a lot of ways of doing these calculations.”

The free radicals discovered by Dellinger’s team would not show up in ordinary smog checks, which detect molecules in the gas state and not those attached to solid nanoparticles, he said.

Even the most modern catalytic converters may be ineffective at eliminating the free radicals. Ironically, even as a catalytic converter breaks down smog-causing pollutants, it may be creating conditions (particularly high temperatures) for the free radicals to form. “You could be destroying some [pollutants] and creating some at the same time,” Dellinger says.

Muffler, Bukan Hanya Sebagai Peredam

Tanabe G Fordan

OTOMOTIFNET - Pada awalnya, fungsi utama muffler adalah meredam suara dari proses pembuangan sisa gas buang pada mesin mobil. Karena dengan absennya muffler, maka suara mesin mobil akan terdengar sangat mengganggu.

Namun pada perkembangannya, fungsi muffler pun meluas. Tak hanya sebagai peredam, kehadiran muffler juga berpengaruh pada performa mesin, tingkat efisiensi konsumsi bahan bakar, emisi gas buang hingga aspek tampilan. Penggantian muffler standar dengan versi aftermarket bisa jadi solusi jitu mendongkrak performa dan penampilan.

Namun, jika ngobrolin muffler versi aftermarket, selera juga menentukan dalam memilih. “Kalau soal kualitas, bisa dikatakan brand asal Jepang tersebut hampir imbang, jadi tinggal model tampilannya dan harganya yang menentukan,” sahut Dalvin, pentolan CK Motorsport. Dengan kata lain, soal kualitas produk dan peningkatan tenaga yang dihasilkan antara merek aftermarket asal Negeri Sakura ini bisa jadi bejaban.

Dari bahan baku, stainless steel paling umum digunakan untuk spek harian. Sedangkan titanium biasa dipakai balap karena faktor bobotnya yang lebih enteng. “Muffler titanium bisa saja dipakai buat harian, tapi konsekuensinya suara knalpot lebih berisik,” ujar Rudy, punggawa bengkel GR 1 Racing.

Sementara untuk peningkatan tenaga, penggantian muffler dengan versi aftermarket bisa melonjak mencapai 2-3 dk dk, tapi kalau mau maksimal bisa diganti berikut down pipe atau bahkan header-nya sekalian. Kalau sudah begitu, 5 dk saja sih tembus, atau bahkan lebih. Lumayan kan?

Sertifikat Jasma Pada Muffler
Pernah melihat plat bertuliskan JASMA yang nempel di muffler yang kamu incar? JASMA (The Japan Automotive Muffler Association) merupakan asosiasi produsen knalpot di Jepang yang mengontrol semua muffler buatan dalam negerinya tersebut.

Sertifikasi JASMA merupakan hal yang wajib bagi setiap muffler yang akan dilempar ke pasar domestik Jepang atau untuk di ekspor ke negara lain yang menandakan bahwa sudah memenuhi standar peraturan yang diberlakukan pemerintah Jepang.

JASMA memberlakukan beberapa ketentuan untuk setiap muffler spek jalan raya seperti, tingkat kebisingan (harus dibawah 93 db), tingkat emisi yang dihasilkan dan mempunyai desain yang dianggap tidak membahayakan (seperti besarnya tabung, jarak tabung ke jalan dan bibir knalpot harus sejajar dengan bumper belakang). Wah..., kalau di Indonesia masih bebas-bebas saja tuh.

bro neh barang dagangan gw yg terbaru...leher knalpot racing thailand merek tsukigi. khusus buat mio/nouvo. selama ini klo kita mo kenceng kan, pusing dengan suara berisik motor kita. skrg uda gak jamannya lagi. di thailand jg ada regulasi serupa yg melarang knalpot super berisik lewat dijalanan. tp orang thailand uda berhasil menemukan solusi baru. mereka mengganti leher knalpot standar yg kecil dengan yg diameter dan tekukannya lebi oke drpada standar. bukan cuma gak berisik. knalpot racing kan terkenal loyo tarikan bawahnya, klo ganti leher knalpot ini atas bawahnya jd enak. soalnya gak terlalu freeflow, sebab silencer masi standar. cuma lehernya aja yg diganti. gw rekomendasiin Las yg kuat buat nyambung silencer ini dengan lehernya. misal las argon. gw tidak menerima pemasangan dan pengelasan.
neh fotonya :



harga sperti biasa PM gw...soalnya ada harga khusus buat pelanggan ring per cvt dan indiglo
bisa COD di cideng jakarta pusat. bisa jg kirim tiki. jabodetabek cuma 5000. drpada jauh2 ke cideng? mendingan tiki aj pak aman koq. hehehe
