How bout this, take the extractor only, dont trade in yur oem exhaust, anything happen u can always revert back to original exhaust? Who knows in the future when u try to claim warranty, the exhaust might be an issue, u can always revert back to original?
By just changing extractor u can measure how much the performance gain and if u r satisfied with it, u can always go again next time to change mid and then later muffler later, since catcon is at the extractor which the only things that is suffocating the oem exhaust, change that first. After all i tink u'll gain like 4-6 hp at the extractor and might be 0.5hp at the other things?
So give it a try to my suggestion.
I also planning to do the same

, because of tight budget also

..hehehe..
so, if only change extractor will cost less than rm300...woohooo, so tempting

...
Just wanna ask, let say I changed my extractor than I still go to service at proton. will they directly said i void warranty

... or if something happen 1st

..
Because I plan to improve my FC, n extractor will really give some effect on that..
