See mb this weekend loh..
TT means teh tarik.. T.T means crying face.. haha..
Adding a bullet helps to compress the air and add backpressure.. When u add back pressure u are maintaining the compression of the engine combustion, which is very important .. When u add back pressure u actually reduce a bit of pickup.. cos when u accelerate ur exhaust velocity becomes faster, but the bullet and s-flow is restricting the airflow a bit by compressing it.. Thats y removing a catcon can improve pickup and low end power..
But then backpressure is still needed.. Thats y auto gear cars need to have s-flow mufflers.. It helps maintain a certain amount of backpressure and exhaust velocity, therefore maintaining compression in the engine.. If u lose compression in ur engine u actually will damage the engine due to the engine burning either too rich or lean..
Theoretically no.. With a firing sequence of 1,3,4,2.. THe air technically clashes when the 1st and 3rd chamber are fired consecutively, then the 4th and 2nd chamber are fired.. But then in a 4-2-1, scavenging effect from a well tuned extractor actually helps to pump the exhaust air out, therefore increasing exhaust velocity and giving much better pickup.. But the problem is each extractor is only tuned to operate at a certain RPM.. FOr example hotbits may be tuned for max scavenging effect at 3.5k RPM.. So the pickup will generally improve until 3.5k rpm.. after that the effect is not as good as a extractor tuned for 5k rpm.. etc..
depends on the scratch and dent.. The dent the bigger it is the more expensive.. Scratches generally no matter how many or how deep on the door, when u repaint u actually repaint the whole door.. Therefore it cost the same to repaint with 1 quite deep scratch or 10 very deep scratches. .
A midbox creates multiple air distortions in different directions, therefore muffling down the exhaust gas sound.. It does create slight amount of backpressure too..
FINAL DESTINATION!
Know ur car better.. Push it beyond its limits, then only u will know what is ur car limit.. U will never know the limit of ur car if u never push it beyond the boundaries!! hahahahaha..
