bus of coz la... their engine so high displacement... duh~!!!
exhaust pipes are bent in certain ways to induce backpressure... so u can feel abit more torque at low revs... but too much backpressure will cause restriction and will decrease horsepower....

QUOTE(gohlex @ Apr 15 2008, 12:37 AM) guys,i didnt meant to be overthinking here, but i got one question in mind, a car mod noob like me, if go to the exhaust shop and say i want a branded fullset exhaust setup e.g hotbits, how am i know that i'm geting the genuine hotbits but not those other brand of similiar item? is the hotbits muffler, bullet and extractor all come with the hotbits word engraved on it? or is there any other way to determine? can somebody englighten me? that depends on what workshop u go to... if u looking for hotbits, go to speedworks...

QUOTE(deepoce @ Nov 12 2008, 11:54 PM) i got a 4-2-1 extractor, 1 bullet, 1 mid-box,s-flow muffler. wondering if removing the mid-box will increase power? i heard mid-box got no effect except silencer? i thinking of replacing mid-box with another bullet..so means total=2 bullet..the power will be better & more fuel economic? Go uphill or Genting also better? did u remove the catcon??
