Exhaust sound

[B33mEr]

Is it related to ecu issue if exhaust flap keep open all the time? My technician told me is my ecu problem issue and ecu needed to be replace....

May i know which workshop said that to you bro? Just check whether the vacuum hose is connected to the exhaust valve or not ... If it is then the valve may be broken .. It's nothing to worry about. I've had mine open for years already :4:

It's not much, at low rpm it sound abit more bassy and throatier ... of course can't compare to the aftermarket exhaust like remus, eisennman and etc ...

Bro, I tried going under my car.. and I couldn't find the cable to remove and put in the bolt

Here's a simpler way of carrying out this mod, without the need of getting your hands dirty, rolling under you car etc. trying to plug, crimp, or disconnecting the vacuum line under the car...just unplug the actuator in the trunk in front of the drivers side tail light..it's simple, easily reversible, and doesn't involve crawling underneath the car

Step 1:

Step 2:

Step 3:

After experiencing the simple mod on a long drive(KL-Penang-KL)over 3days,I've connected the switch back to it's original place.I don't feel that the sound difference was errrr 'different' enough to warrant it permanent status.Yes,it was a tad louder(with an accompanying ever so slight drone) during cruise especially around 110-130kph and when accelerating from medium speeds,but it wasn't any different,to me at least.Just louder,not nicer loud.
Anyways,everyone has their own take on this.This is just me sharing mine.. so I'm back to square one again.
