New Boomerang

ya i also find it better , when you like your car , you wanna protect it , and this is what you should buy ! you put it on once and forever thats it , and your car , is always there !
great system i find !

I disagree slammed si. The DC 4-1 usdm header would severely restrict any further modifications like cams or forced induction. The difference is bigger than you think (more like 3-4) and with a hi flow cat the difference will be even bigger than that. I have done long hours of research on the subject. For the extra $250 to get a JDMITR, it will be well worth it, especially in the long run.

Check out this thread. There are plenty more but I don't have time to look. I had better stop before redcherokee yells at me for getting off topic.

now you mentioned the catalytic convertor, we are just talking about the headers and what their possibilities are. flow is flow, who cares what the name plate is!!!
