bought a fgk for my l2 kancil.it was just the tail section without muffler.only tips.so join the end twin tips till the front downpipe.
the sound so loud:_: ,sounds like na when fully boost.power also good but too freaking loud when cruising.
bought another 2 muffler for centre.now got some sound,not loud.no more fierce sound,no more power.but good for cruising
piping 2 inch
if u buy 2nd hand branded like fgk or tanabe twin tips it will be around rm600 with muffler and twin tips
if custom made,prices will depends on shop
