I see ,the Fiesta eco 1.0 turbo lack of LOW end torque
Is a wise to remove all the exhaust system and filter ,I am sure u can feel the pick-up power

Hi all sifus, i am thinking of changing my exhaust system for my older generation myvi EZI auto version. I travel 50-50 half in highway, half in city. I hope that sifus can recommend me the suitable exhaust system for the car. I am hoping for a more pleasant and quiet ride (not loud loud exhaust sound). I would also like to ask about the difference between long extractor and short extractor, the type of metal and the brands.  Thanks in advance.

I go survey at another exhaust shop ,foremen give me another solution for pick up.

Still stick to 4-1 extractor , but add 1 bullet at center ,he say can gain a bit pick up and also silence the noise ,but top speed will decrease a bit.

is this true ?
