Had this for at least more than 6 weeks. It came, it fitted, and it went booom booom at first and now vroom vroom. guess what it is?
the answer: a Ferrita 2.5″ catback exhaust system.
The exhaust in its packed form, looks just like the one in the photo below. That’s not my exhaust, but my mind was too preoccupied on getting the exhaust fitted as soon as possible, that I didn’t take any photoshot of my exhaust except the “big lumpy photo” you saw earlier.
When I first drove my car off with the exhaust installed, I was wondering what’s the loud rumbling noise about as I stopped the car in a junction. I thought some beng cars were beside me, and it took me awhile to realise it’s my new exhaust that’s rock’n and roll’n!
The initial run in period was a test of my nerve. Why? The exhaust resonance was loud, and I mean LOUD. Although the exhaust is supposedly a quieter version which Ferrita has specially manufactured for certain country, I guess my mind interpreted the noise level literally, i.e. “quiet”. I can’t imagine what it will sound like if I were to buy the ‘original’ version.
In anycase, the staff from Ferrita (actually it was the top guy, Micael, who responded!) was nice and patience in responding to all my enquiries. As he said, the exhaust needs to go through a run-in period, so that the heat can melt the plastic in the muffler that contains the fibre material. According to him, the fibreglass material, which is the one of the muffling material used to absorb the noise, has to be packaged in plastic enclosure for health reason (probably the health of the workers who are involved in the manufacturing process). Therefore, before the plastic can fully melt (and disintegrated), the noise level of the exhaust will be higher than expected.
Was he trying to pull a fast one on me? Thank goodness, he wasn’t.
So I was told that the average run-in period is 2000km. It wasn’t until 8 weeks later, close to 4000km of driving, did I finally experience a ride that’s close to my initial expectation. The exhaust almost mutes like stock as the car warms up. Once warmed up, the exhaust rumbles with a low bassy note, as if trying to remind me that my car has a ferrita herritage. While I would prefer having a resonance level of somewhere between warming-up and warmed-up, I am a happy man now. The car pulls better now, with little or no lag at low end, but strong yet smooth at mid and high. All these, while yielding a sonic note melodically.
3 weeks ago, we took a video shot of the exhaust in operation; When the car first ignited, as well as the drive itself on the highway. My mind might be playing trick on me but it does sound quieter now (just slightly, if any, but still bassy) vis-a-vis 3 weeks ago 😀
Due to the bassy nature of the exhaust note, the low pitch note will probably be inaudible unless you have a good speaker, or using a stereo headset!
edit: took another video clip of the car accelerating from 40km/h to 140-150km/h. The car really feels silky smooth.
