change the spring also la? maybe the srping got soft ady and go senget when you swirl your kelisa?
My new exhaust tail end got a little bit of rust.
Went back to the shop and the boss says my engine is 'good' and so got some vapor in the morning and this causes light rust at the tail ring edge. He says many town driving cars also got the same issue one, unless i rev for a long distance then 'maybe' the rust is gone. true or not bros .. ?
The rust is because the exhaust pipe is not stainless steel, it will continue to rust and rot. Revving it will not make it solve it.
I got the same problem too.
The original pipe on my has rotten so much until the exhaust hook section. So I go for a replacement at one of those 'exhaust specialist'. The foreman told me he's replacing with a stainless steel pipe, won't rust. Charged me RM180.
After 3 months, I saw some rust just like yours. Went back to the specialist, he told me my engine still good, still producing some water vapor in exhaust, and the little rust is normal. I was mad as I know (at least to my knowledge!) that stainless steel won't rust. I argued with him, then he just grind off the rust and spray some silver paint over it. I know it won't work and don't want to argue with him any further.
About few days later, the silver paint peel of and revealing some new patch of rust.
Bottom line is, I got cheated. As he told me it was stainless steel, turns out it is not. Next time just go chop shop to look for Kelisa exhaust pipe. As I see it, certain batch of Kelisa comes with good pipe that won't rust. Other unlucky one like mine, will rust.
