Then Change to 4-2-1: (Stainless Steel, No more clearance issue) (Power starts at 1.5k~2k RPM)
After 2 Days: (Stainless Steel change color to Yellowish after Heated by Exhaust Gas)
Overall comment is 4-1 is very good for track and Drag as it power at top range is still better than 4-2-1. It does suffer in town driving due to need to maintain 3k RPM and Low clearance.
The 4-2-1 is more suited for town driving as the power starts at 1.5k~2k RPM and it does not suffer low clearance issue. The drive is smoother but less powerful on the TOP End RPM if compared to 4-1.
Yellowish mark can be used as a tell tale sign that a Stainless Steel header has been used before.

Wow..the color damn nice. I saw a 'words' on it. JASMA? SPOON? Hehe. I also saw some stain marks on your head cover. Leaking? When you will fix it? Hehe..
The stainless steel extractor looks so nice.... No one can match you during standstill pick up now...
But the engine bay looks like a mess....
Spend some time clean it up la bro... exterior so dam nice but engine bay spoil everything....
Actually the valve cover rubber seal already harden so oil vapor is leaking out and cause the stain.
The valve cover dirty and screwed paint job cause the engine to look like messy.
The tag is "OTTO Racing". :)
Planning to remove, clean and paint the valve cover when I change the LMA and timing belt at 70k~75k.
