headers make a pretty significant different for peak #'s and area under the curve. Likely more under the curve vs. peak to be honest. Gobs more of midrange torque, too.What are the gains? Is it worth the price and install?
or do what many do and get the touring muffler or just weld some resonators inthe only way i would buy header is to sell my corsa extreme and get a full ARH.
Cosra extreme+headers= super rasp!
