what up y'all! just wanna know if a b16 header will fit on a d16 motor? are the primary flanges the same?

 

no they will not fit.

 

thanks john666.. because i have a jasma header but downpipe is a smaller diameter than my stock b16 header. what makes it different? a d16z and a b16 header..

 

im guessing the head flanges are different

 

what else is different? is the length of the secondary longer or shorter?

 

Yes, the flanges are different. Also, for future reference, there is no such thing as a "JASMA" header. The JASMA (Japan Automotive Muffler Association) badge indicates a type of certification, not the manufacturer.

 

ok yeah, it's an approved header by jasma..
