NEWS: PAYMENTS ARE NOW BEING ACCEPTED.
Please paypal to paypal@grimmspeed.com and put in the notes, your nasioc screen name and "nasioc crossover group buy". Since we are now at the cheapest price tier your total will be 109.99 shipped to lower US 48.

Due to customer demand we have decided to start our first Nasioc group buy!!

Get rid of that teeny weeny stock exhaust crossover and replace it with our new HiFlow Crossover. Inner diameter is a beastly 45mm compared to the 38mm stocker. This unit is built from mild steel tubing throughout and maximizes exhaust flow from cylinders 1 and 4 to the passenger side manifold collector for faster turbo response. A big problem we face as boxer engine owners is spool up time... one of the reasons being the driverside cylinders are sooo far away from the turbo. Add in a tiny stock xover pipe and it makes it even worse. If you want to stay with the stock setup, one of your only options is to increase the diamater of the crossover pipe allowing the exhaust from those two far away cylinders to get to the turbo sooner. Our enlarged crossover does this for you.

For a kicker....all of these pieces come standard with ceramic coating to keep that exhaust flowing and the heat confined in the pipe.


Pricing Tiers are as follows:

1-9 participants: $114.99
10-15 participants: $109.99
15+ participants: $99.99 <-- oh the insanity!

Want to add double heat protection? As an option we can heat wrap your piece for $45.

Shipping is a flat rate of $10 to the lower 48.

Fits 02-05 Turbo OEM Manifolds

Group buy ends on February 26th (duration of 3 weeks)

Thanks to everyone for your continued support!!

yep you can use your stock gaskets. we made the piping/flange about as big as you can go with while still giving yourself a little extra space for the stock gasket.

Not having the flex joint, would that be a problem. I had already got the pnp manifolds from you and anything to help spool is great. I am just worried about it cracking or something without the flex joint. But I'm not running one in my up pipe either so....just curious.

Since these are larger diameter than stock: 45mm compared to the 38mm stocker. Do the oem manifold outlets that mate up with the crossover have to be port matched? OR does this larger crossover match up flush with the unported stock outlets? To get full efficiency out of this mod I presume that the outlets need to be gasket port matched.

yes it does. we made sure not to make the pipe TOO big so you dont have to go buy different gaskets.

Thanks,
Mike
to tell you the truth, i'm not sure what the standard is when other vendors take payment in the group buys. could anyone advise us on what "typically" happens regarding payment in group buys? i dont want to make it harder for people so i just want to make sure we are in the norm.

got you on the list. when i was prototyping this piece awhile back i put the stock heatshield on the pipe. i remember doing a little modification..but i cant remember exacty what i did. i think that i just took the brackets out and it fit right in.

good question, people ask me about this frequently because we are the first in the industry to offer one without a flex. What i can tell you is that from testing one on my car for a long time now, i have had zero issues with this piece(my prototype wasnt even as nice as these production ones). If you take a look at the stock "flex", it actually doesnt even flex that much. My thoughts were; i put 1000's of miles on my test piece with no issues, the stock piece doesnt really even flex that much, we will gain higher flow with out a flex, and it will be more cost effective for you guys....these are the exact reasons we made the pipe we did. A few customers have had to loosen the 6 bolts that go from the collectors into the head to get theirs to fit perfect but that really isnt a big deal. so in short, i have yet to have a single problem with even my prototype that i have had on my car for a long time now.

wrxed is right. to make MAX potential from this piece a mild porting just to one port(passenger side collector inlet) would be a good idea. However, you definitely do not have to do this to find gains. I suppose i should be pumping our pnp manifold services here but i really dont care...just being up front and honest.

thanks for all of the activity on this so far guys
