TRD headers are meant to be used with their stroker kit hence the slightly larger primary pipe diameter. CEs ones are ported,flowed and coated stock headers. the difference between the 2 is quite noticable and as SD mentioned Northy had TRD but got rid of them over the CES as the gains were better and more noticable.
TRD may give you slight gains top end with the bigger pipes and a tiny bit low down but if it is mid range and low speed torque the CES ones are the go.
I was made to believe from Honda users that 4 2 1 is the way to go with low-mid range torque. Unless their VTEC engines work differently compare to VVTL-i.
That is one of the reason why TRD came up ...........
Guni the TRD headers are exactly the same as stock headers. Same design but with slightly larger primary pipes. Might pay to do a bit more research before you ask some questions you will get flamed for.
And yes they are 4-2-1 style headers.
Thank you.
If my research answered my own question, there would not have been a need for this post. I was after more information and personal feedback from users of each product and would eventually then come up with my own conclusions. If others wants to get personal about question or queries that I may ask then too bad, because I will ask these questions to get the information I'm after.
Its a general question about personal experiences with a product. If I were to be flamed, so be it. I will handle it maturely.

Well expressed. My sentiments. People need to realize that getting responses based on personal experiences is very important.
