The answer is yes to both. pre-2009 generation of Honda/Acura motors all featured full on header(s) (maybe 1 or 2 cars out there that didnt so dont shoot me) The reasoning they switched it from my understanding is because integrating the header to the head allows them to place the precat closer to the exhaust port, warming the precat quicker which apparently helps with emissions. From what I am seeing though it's not really a performance disadvantage.. K20s with similar mods to K24s put down expected numbers.. the K20 has a slight HP advantage where the K24 has a slight TQ advantage.. which I am gonna say is more based on the head & cams themself than the exhaust. The integrated head seems to be working really well for turbo manufacturers, PRL(?) has already made 370WHP on the '12 Civic Si. Someone more up on the engineering can maybe chime in as to the WHY they make the head that way now.OK. I knew that but there still is a "header" for 4 cylinder cars.
example - integra, rsx
It seems like most newer Acuras have the header integrated into the head.
The R20 and K24 (2012/3 variants) both feature an integrated header.Quick question while im working and cant take time to find the answer. Are we talking the 2.0 2.4 or both?
its a conservative drop on the ILX, but yes he can go at least an inch lower. But it depends how much trouble he wants to save himself from. Its not fun when you have a slammed car driving around town and new areas not know if theres going to be a huge speed hump that will damage your front bumper or other things.Lookin real good. Is that yours Veilside?
lol It can go much much lower my friend. Still a lot of wheel gap, especially for 18in WHEELS... not rims.
