harganya bergantung sama tipe mufflernya, starting di 4.5 juta kalau tak salah. itu untuk tipe muffler yang universal. kalau yang bolt on / sudah di desain spesifik untuk suatu mobil sepertinya harus order deh :big_think:

Posisi di sby ya?pakai kansai aja gan.hehehe.untuk yg 41 maupun 421 tempatnyabwalaupun sempit ttp bisa kok.tp ane lbh menyarankan pakai 41 drpd 421,kareba 421 lbh boros saat saya pakai di t31 saya,

Pasti lebih boros karena maunya di-gas2-in terus supaya kedengaran suaranya yang mantab.

Backpressure and Exhaust Pipe Size

Q. Why do engines need backpressure? Won’t a larger exhaust pipe give my 944’s naturally aspirated engine more power?

A. I’ve always understood that you want to keep the exhaust gases moving, even once you get them out of the cylinder. One thing that will cause the gas to slow down is a sudden decrease in temperature, which is one reason why auto makers don’t try to cool the exhaust manifold. The other thing that can cause a decrease in flow velocity is rapid expansion and turbulence, like going from a small passage (like the exhaust port in the head) to a 6-inch pipe.

A smaller-diameter pipe geometry will tend to keep the flow rate up, but it will also lose heat more quickly (less exhaust gas per linear inch of pipe). However, a large pipe will slow the velocity due to expansion. Worse still, the exhaust is constantly cooling from the moment it leaves the cylinder, meaning it’s getting denser and slower. See the problem here? It’s all about compromises. The proper pipe size is going to be influenced by the flow rate (volume rate, which is related to RPM and engine displacement), exhaust velocity (again related to RPM), exhaust temperature (constantly changing, and as high as 2,000&Mac251;F, if I remember right), and undoubtedly an array of other factors. All of this is dependent on the application: is this a street car, a race car, or something in between? Where will the engine spend most of its time? Idle, full throttle, part throttle?

I’ve also heard the thing about back pressure, but I believe that they’re really talking about flow velocities. That is, if you can keep the exhaust gases moving in the exhaust pipe, they will cause a small reduced-pressure area behind the closed exhaust valve, in the exhaust. This happens because the gases have momentum. They move away from the valve, creating a localized reduction in pressure. When the exhaust valve opens, this reduced-pressure zone will help evacuate the burnt gases from the cylinder. Or so the theory goes, as I understand it (two disclaimers there).

Kalau saran ane pribadi

Konsul ke produsen knalpot yg benar2 well develop utk mobil yg akan dipasangi

Utk Indonesia = Standard Adi Knalpot

Utk mesin NA modifikasi knalpot harus hati2 / dihitung dengan matang / lebih complicated drpd mesin Turbocharged......bila kita ingin hasilnya improve di seluruh powerband

*bukan seles knalpot*

Mobilnya apa ya pak? Kalo aftermarket partsnya lumayan umum, ya beli aftermarket parts aja.

Kemaren mobil saya ganti midpipe custom di SP motorsport lontar, bekas promobile. :big_peace:
