Agree..2 inch piping is max for 4g18p

Bro,how much for that 2 inch piping mendrel bend??

basically how much the cost for mendral bend piping?

I went to 2 WAI HENG's and the first one (Setapak XIN EXHAUST) was totally screwed because their recommendation was totally wrong. The setup was noisy and the car vibrating like mad when you step on the accelerator. The reason is because of the loud humming sound from the mid and rear muffler. After that I changed to a more silent setup in Puchong where I was made to pay RM550. They re-did everything from the front till the rear and the guy also seemed to know what he is doing. However on one fine day, I drove to Cameron Highlands only to know my top speed stays at 170km/h. After that, I went to Genting and came back with a damaged/leaked mid muffler which produces loud humming sound. Not long later, my O2 sensor was broken.

In total, I've spent RM1400+ on WAI HENG but now, I don't use anything from them at all. It's only about 2-3 months and I had everything including piping changed from another shop in Ampang. This new place that I go to have better quality mufflers and are more silent as well.

As I say, what we want is different and mine at 6,500rpm is only some buzzing sound I want a setup that is as silent as possible.

Problem settled at Jian HAng.. And met another Xin exhaust customer over there.. So...

And 1 more thing, my dad saw my car, kena scold like mad say why i go do my exhaust system!
Ask me change back everything! WALAU!!
So any interested please let me know, letting go whole set rm700.. Rugi also no choice.
