Here is some update. Actually last month i ordered 'Exhaust Electric Cut Out' which produce by Raceland. I asked my friend to get it shipped from US to Malaysia last month and it arrived yesterday. Below are some pictures of the electric cut out.
wiring and remote control
hero of the story, the electric cut out, complete with piping :)
catalogue... for future reference :P
Woke up early today to fix this exhaust cut out. yeah. thank god the exhaust shop that i always visit doesn't close today, yeah on christmas :P if not then i have to go another day which i think i might be busy...
need to do some adjustment to the piping since the exhaust cut out is quite big...
sorry i forgot to take the picture when the welding job finished. too busy looking at other performance parts in the shop :P
some video taken from youtube if you guys still dont get how this thing works :)
and below is my video. Sorry for the lousy video quality. Just using camera phone.
Can you guys spot the difference in sound? yeah. These are some of the benefits - this cut out enables us to bypass the muffler hence increasing horsepower and giving car an extremely throaty rumble. Since you all know that i'm using s-flow type muffler so, my high end power is quite suffocated. After i installed this cut out, my high end power is improving a lot since there is no more restriction in the flow but the low end power i can say drop a bit. The good thing using this cut out is, i can choose wether to use my standard setup or free flow setup. Cool isnt it? I think i wont have any issue with the authority since i can now have the ability to control the sound of my exhaust :)
p/s: this 'weapon' is very effective in drag race :P
