hey i got the same car... have fun actually finding parts that fit except for the intake. i have the aem intake which fits fine.
header was too long at the part that connects to the cat so i had to have that cut and welded.
they don't make a full exhaust either so you can go rice and just put a muffler that don't do sh*t excpet make noise. or you can try to find a cat-back which they don't make, or atleast i haven't found, and have that cut and welded also cuz the b-pipe is too long also.
the parts you found are for the EX model, they won't fit the LX model properly...atleast that's what i came across when i bought everything.
