+1 for Megan Racing quality being POO. I had their downpipe for my 240 and I had to cut and clock the flange for the turbo outlet a good 35 degrees for it to fit properly…

Also, their coilovers for 240’s last a solid 2 years.:retardclap for $900 down the drain!

BUT, as long as it works, in your case, its probably better than OEM. I don’t care how “crappy” a header it is, flow is flow. I’m sure that header will flow better that your stock manifold but what do I know, I hate Hondas and know little about them…

As for the TB spacer, IDK about heatsoak and whatnot, but I do know that the longer the intake runners (as in the further the butterfly is from the valves) the more low end you will have. Even if it is a minuscule amount its still a gain, maybe not what they claim you will get, but a gain no less. Also, I’m sure the air will be cooled off more because of the slight increase of the low pressure area in the intake manifold (in theory, shooting shit on that one!).

And yeah Chris, when my vtec opens up at 9500rpms on my WRX, it’s sick. I can get some serious rally racing done then.:rofl

George!!!Haven’t seen you in forever! civic is almost done,you can drive it,then you will like hondas my friend.
