So I put the header on last night. Before I did, I took a picture of my DC header's clearance (big ass dent and all). Getting the new catalytic converter hooked up to the exhaust today (After I drive it over to the shop.....open header). Hoping to feel a difference with the switch. The 2" vs. 2.5" plus the removal of the dent (lets see how long I can keep this one without a dent) FYI the Dent is from a ex-girlfriend driving my hatch when I was drinking (she effing sucked at driving over speed bumps) And the JDM ITR header. Before install.....I sat them right next to one another and it looked like the JDM header was about 1/4" taller (so I figure a 1/4" less clearance. So.....yes the stuff I read was true.....it sits pretty low. But I am optimistic in its survival on the roads with me behind the wheel.....famous last words.
