Builded full smooth undertray and new high flow exhaust pipe. Exhaust pipe comes out from drivers side and that has two purposes, reduce weight of the pipe and make air flow better behind the tire. At the moment pipe is quite far behind from the tire and I wonder would it be better if I turn the exhaust exit towards the front tire to get it closer the tyre?
Exhaust noises arent really high on the highway but on lower speeds you can call it race exhaust when the turbo is not yet spooling. I dont yet need no ear protectors inside the car, but the interior will be stripped out in the future. I was muvh quiter than I expexted it to be
. I will try to measure the desibels of the new exhaust as soon as I get some dB meter in my hands.
New undertray has impoved the gliding properties a lot and Lupo start to glide as good as my old seat. Still I think it will at least those rear skirts to be at the same range with Seat.
I ordered full set of Bridgestone B381 Ecopias 145/80R14 to be able to use the stock magnesium rims and to get cleaner looks to the car. I also did not like the gliding properties of those Toyos :/. Well now when I have the set I can compare those two in paraller. I also have one wicked looking idea conserning the wheel covers. It depends on the tyres will it work as planned.
