you dont even need the piping..you can leave the stock pipe if you want((the ugly plastic thing)) the piping wont help u as much as the intake. i have it and bought it from nopi also..but it came with an adapter. i DID hafta buy different screws tho..and due to the angle of the connector, one of em can be tricky to get in, just so u know.
2 THINGS THAT BUG ME ABOUT IT:
1) it just kinda hangs there w/out any reinforcement..probly wont be the case with the accord pipe..the pipe should hold it. or u could rig something yourself. dont hurt anything the way it hangs there..but i just dont like it.the stock plastic is connected and flexible...but i just cant imagine what its going thru over the bumpy road.
2) my "usual driving" combination of highway, but mostly city MPG's dropped from 19 to 16mpg. kinda sux... NOTe: i have an auto...and the filter makes it stay in third gear alot longer..and it rev's higher in every gear, so this is probably the cause...wont be as bad with a manual car.
WHAT I LIKE:
ya know how the car kinda suffocates right now between about 5400-6800 rpms? all noise and little power? well that'll dissapear real quick. i can actually FEEL it when i peak at 5600 rpms.((hp or tq... i cant remember which peaks there) but you feel it get pulling real hard to there..and then just about as hard all the way to the redline...its a nice feeling, yes it is
JUST SOMETHING YOU'LL NOTICE:
after installing, when you start your car up...you'll hear a slightly raspy sound...almost like a mini-blower. you can now hear your car sucking in the air. sounds kinda cool. a post a made a long time ago when i put it on back in ....NOV? maybe. may still be accessible...it gives an indepth review of what i thought after installing and driving. see if you cant find that.
hope this helps
