HiFlow Crossover v2 Group Buy - yes finally here
PAYMENTS DUE TODAY 6/13
Please paypal amount to [email protected] This is dedicated to everyone that has been bagging on us to get this GB started Welcome to our Version 2 Subaru Exhaust Manifold HiFlow Crossover. As many of you may or may not know, we came out with our 1st Gen crossover the end of last summer and had sold out of them instantly every time we got a new batch in. Well we've decided to step it up a notch with our first revision of the crossover. Meet HiFlow Crossover v2. Immaculate welds, smooth as butter 2" stainless steel, thick 12mm stainless flanges. you cant beat the quality of this piece. Customers have seen up to 15 HP INCREASE when combined with our PnP Subaru Exhaust Manifold. This unit is built from 2" 304 Stainless Steel throughout, maximizing exhaust flow from cylinders 1 and 4 to the manifold collector for faster turbo response. This unit has a flex in the center to allow for easier installation. Add on our amazing Ceramic Heat Coating for a VERY SMALL fee to help keep the heat in and speed up those exhaust gasses even more. Specs: -HUGE 12mm stainless steel flanges -2" stainless steel piping -flex joint -pure hotness -direct replacement of tiny/restrictive stock crossover -Boost transition is improved over stock -Mid range to High end HP/TQ increase -Fits 02-05 WRX, 04+ STi, and 05+ LGT -We believe also fits some dual port jdm turbo manifolds however we have not personally tested. When installing we advise ditching those used subaru stock gaskets and use our new RemFlex 50***37; crush graphite gaskets(20 bucks). If you havent used these before you are missing out. If we go over 15 there will be a delay as we will be out stock for a short period..so if you are past #15 on the list yours will be shipped 3 weeks after the GB has ended.

Ok, I'm dumb... how/why would I see any increase of power in with this pipe vs, OEM pipe? The ID of the OEM piece is the same as the exhaust collector/manifold thingy.

Thats interesting. They look the same to me LOL.
What I dont get is...The worst part of the crssover IMHO is the flex joint creating turbulence in the pipe which hurts flow. If you still have a flex joint, then what increase is there? Cant be size because if its much larger you are actually losing exhaust energy and reducing the speed of the exhaust gases. Wouldn't this actually be hurting performance due to unequalized pressure from the different banks of the engine? and isn't that what killed the injen pipe in the first place? |

After seeing your new pipes, this almost makes me want to call in a favor and ditch my Borla header. That's high praise from a huge header fan. Maybe you should have a combo deal with these and your ported and coated stock manifolds and call it the GrimmHeader?
