Two into One exhaust scavenging
the alternating pulse from one side can actually create a vacuum to help pull flow from the other.
Even ARH Headers come with a new Y, looks very much like the Magnaflow Y
My Maggy Y ($27) welded in with SS Mandrel Bent pipe ...
stock squash bent and compressed Y pipe :
it's all the little pieces that add up to the bigger results in the end, its just a supporting mod that wont measure much on its own, just like a Catch Can or a Jet 180º T-Stat.
-add up enough supporting mods that only pick up a tenth or two on their own and before you know it you've dropped a full second off a quarter mile.
I started last Summer with mid 15's, now I'm at 13.8 and still dropping.
I cant quite afford ARH LT's, ($1600) + Ceramic Coating ($300) but will have JBA shorty headers
to replace my ugly cast exhaust manifolds soon...for $500, the $27 Y- pipe seemed like a no brainer.
on the intake side I've got an Airaid, home made Ram Air feeder tube, Fastman 85mm Throttle Body
and a Tuner capable of Data-Logging and custom CMR tuning to make sure I'm optimizing everything to run together.
