So there’s been a lot of talk on loud suburus, most recently with kina @gashwin on this thread here http://www.kenyatalk.com/index.php?threads/drunk-driving-weekend-manenoz.34204/
For clarity purposes, I’m going to explain exactly why some of these Subarus have loud exhaust systems.
Unlike what most guys assume, si ati watu hutoa silencers. They simply upgrade their entire exhaust sytem to increase vehicle power.
Shifting from stock to turbo-back exhaust systems immensely increases the airflow to the turbo charger. Here’s a short vid on it:

For optimal power, Subarus are then taken for mapping, where the entire ECU is remapped to reprogram the engine to increase horsepower and output. Kuna several experts wa hii maneno in Nairobi.

At this point, the subaru has already built up sufficient power for most guys. But, for guys who still need an extra boost, there’s the option of installing a bigger STI turbocharger, which might lower the torque but increase overall power. That’s when a dyno tune is needed.

Alafu kuna what we call Antilag. If you’ve driven a turbo-charged car, you know that feeling when you’ve built up sufficient boost at the right rpm alfu you encounter a bump, corner or a slow driver and you have to wait till the boost kicks in again. That’s caused by reduced airflow into the turbo charger. That’s called a lag.
So, to maintain a great boost even when you slow down, some guys choose to antilag their cars. Basically some of the air flowing into the car bypasses the engine and flows straight into the exhaust pipe, mixing with petrol vapor and causing explosions, pushing the air pressure towards the turbo-charger, hence maintaining a great boost.
Here are a couple of antilag videos:

Kutoa silencer ni stunts za watu wa Toyota :D:D:D:D:D
