This the same design? or is it?. You be the judge.

Has mr. self destruct tested these? Im looking for the pros and cons.

Thanks

dc jdm 4-1 has larger primaries a true 2.5 in collector and weighs a good bit less than the jdm itr header.

I personally think that the JDM is better. its much better made than the DC ill tell you that..


plus its OEM JDM Honda parts....

i would suggest a comptech tig welded header and test pipe if you have a b- series motor. if you have a sohc i wouldnt buy one. when i had my sohc i bought a dc 4-2-1 ceramic and it didnt do shit to my knowledge. my 4 cents.
