Hey bro, nice welding there..
my bro jus give me sample pipe that u use, very heavy man...
Any reason u use that thick pipe??is it because of high boost durability??
Ya..hey punk..thanks
...i use 304 gred,3mm thick stn.stell..like usual other exs fabricator use..
nope.. its not to heavy for me..compare oem header...but for sure all depend for header design.if log type sure really light...more long,more material right...but u can just imagine if its cas iron, all runner 17"length(out side conner) x 4 =68"=5.6'...weight???
reason...need more hot and lasting from band,twist,crack(if wrap) when hot,can hold more turbo weight..
Hope other Sifu also can help to answer your question...
