eh??? How come got ppl mention my name here???
I seldom do exhaust mods one le... Ben Soon @ Masaigot few of my mech customer do there... Din really look at their workmanship, but never heard them complaining la...
Another one old timer would b TopSpeed @ Tmn Sentosa, quite a old shop n famous, carry M7 products too... Oso his son is a race driver, they got some track cars there... They somehow got connection wif kazama if I not mistaken...
As for me, I did at a fren's shop... K-power @ Mutiara Rini... Very good workmanship, he really pay attention n do stainless stell welding nicely for my 4" bling ling exhaust piping...
I suggest u to go to a few shops n see wat they suggest n oso to get a quote...
Also, since u say u cannot tahan the sound... Got consider doing halfpipe/sideplant/watever they call it... Can "on" when u r in "need for speed" mode... N "off" when u on paktoh mode or see roadblock... But from my experience of using it last time, the throttlebody easily got stucked n can't close back... So if u wanna do tis mod, try to find good quality ones, dun bother to mod throttlebody there...
These r just my 2-bulus... Sekian terima kasih... Happy modding!!!
