Hi all!

After the frustrations i encountered trying to find a quality reasonably priced midpipe (see here: http://alltrac.net/phpBB2/viewtopic.php?t=24126 ) I decided to contact Berk Technology to see if he would be interested in making us a 3" midpipe.

He said he would be willing to make it if there was enough interest from the community, thus this poll. He doesn't have a price yet since there isn't even a prototype right now, but I made it clear that we were looking for a better quality option than the $200 SSAC from 935, but something less expensive than the $410 Aussie.

I chose Berk simply because he is local to me so I could provide my car for test fitment, and he has a good reputation for his fabrication skills and business practices from mr2oc.

His website is under construction right now (www.berktechnology.com) but here are a couple pictures of his handiwork:



He also specializes in GT30xx turbo kits.


So, lets see what interest we have for a new product for the GT-Four!!!

Do you think he could create a 3" downpipe with a pre-cat in it? California Smog sucks and I want to skirt about as close to legal as I can.

What we need are 2.5" midpipe and cat backs. there are lots of 3" options arnt there?

you can find a 2.5" HKS sport catback if you look long enough

lumbercis, i sent you a PM

@Corey Darling. No, there is only the SSAC or Aussie.

To be perfectly honest, I can't ever see a reason to put anything but a 3" exhaust on an alltrac. 2.5" has been dyno-proven to be a restriction even on relatively low power mr2s. And what happens when you want more power? You would need to re-do your whole exhaust system. If you get a 3" you will never have to worry about your exhaust again. The ONLY benefit of a 2.5" system is sound. But honestly, if you just make smart choices, you can have a 3" system that flows better and isn't loud at all.

By adding a good high flow cat wont you eliminate this?

Not sure what you meant but even if I add a high flow cat to the mid-pipe or wherever it's supposed to be, I still need to show the pre-cat for a smog test and the now ominous roaming smog checks performed by our lovely police state.

How many interested parties would it take before he is willing to build a midpipe for us?

What is a pre-cat? A second cat?

I have had email contact with Bryan(Berk) for my turbo kit. He is very kind and responds quickly. The DP looks good, and so do his turbo kits.
I already have a full 3" aussie system.

If any of you have dyno proof of a 3" being more powerfull than a 2,5" at low/stock hp I would love to see it. Have been questioning this for a long time now.

SARD already does them. Dunno if it's discontinued though, but I'm loving it!

blinging.. i could imagine what a pain in the ass it will be if the cat failed..welding it on would be a pain and hoping it wouldnt crack is another story.

If the Aussie MP could be replicated that would be great (that includes offering a hi flow cat option)

That SARD is badass, if he could build one of those and have it fit I would
be all over it. I would love to be back to stock config with emissions just
in case (already have a hiflow cat in my midpipe to replace the stock
secondary cat).

Do you know what the part number was for the Sard Downpipe and who did you purchase it through?

now thats something ive never seen....

Meurz, where did you find that?

lots of good stuff here
