New ND Midpipe

[awales74]

Still enjoying my RoadsterSport Race and now looking for my next project.

I've read that there is a new midpipe for the ND in the works. Something about a higher flow cat? Is this true -- is it a different product or just an enhancement to the RoadsterSport? Would it carry roughly the same legal restrictions or does the higher flow cat make it off road only? Would it come with a different resonator that keeps a little more control on the sound? Any idea of date?

Yes, new MaxMidpipe is coming. Been saying that for many months, but almost done. No CARB version yet, though that is planned....but it will be ANOTHER version of the same item, not the same item. The CARB version needs higher density core, doesn't get the 5 inch 200 CPI for track use, but would still get big 5 inch diameter cat that would easily flow better than stock. That's the plan. We have CARB midpipes and cats for NA/NB....so we hope to complete the catalog with CARB midpipes for NC and ND.

Saw a sneak peek on another forum. More details?

[Brian]

Same as you read in the other thread (pic copied below so others don't have to go searching). I talked with production again later today, everything is complete, but we are at least 30+ days out from inventory on the new item.

Sound check?

[Brian]

On my wife's RF for 437 mile drive to Laguna Seca...with supercharger (makes entire system louder because you are blowing so much harder on it, like blowing harder on a whistle). Wife approved with supercharger.

Any updates on this Max midpipe? When can this be purchased?

[Brian]

Don't have exact date yet, waiting on the factory. Best guess is we are still at least 60 days out.

[awales74]

Not as much fun as waiting for the SC, but still entertaining.

Since you’ve been in testing with it, I’d imagine you’ve weight the new vs current midpipe?
Any numbers?

[Brian]

Don't have final weight. No point in taking the weight before delivery of actual production part, proto versions always have extra welds and that throws off the weight. Nonetheless, it will be heavier than our current midpipe because both converter and resonator are bigger. The goal of this item is not the lightest midpipe on the market, the goal is getting as much sound control done in the midpipe as possible with flow to handle all out performance from E85 builds, superchargers, turbos, etc.

The BIG news is we do finally have date for delivery of first batch....December 15th! Will activate item on site for pre-orders at least 2 weeks prior.

Will this new Max midpipe design matter if the ND would be a Manual or Automatic transmission? I see you have noted that it has not yet tried on a Automatic transmission ND? Is there any obstruction underneath the transmission that will prevent the midpipe from installing properly?

Also I just bought a couple of weeks ago the MaxTorque Ceramic Standard Length Header, before I placed my order I informed sales that my ND is an Automatic Transmission. Will the transmission vary with this header? Does it matter?

Thanks in advance.

[Brian]

Header fits auto and manual....that we checked long ago.

Midpipe is a different question. The auto trans is a different shape, fat at the bottom by comparison to the manual. So, fitting manual trans does not tell us if the midpipe will clear auto and we need to get an automatic on the lift here before we can answer that fit question.

Thinking of pairing this with my SSTT on an otherwise stock Club

1.) What changes to the sound can I expect? I've read that it lowers pitch a bit, but not clear if overall volume will be increased.

2.) Would power improve in any meaningful way, or would I need to tune to take advantage?

[Brian]

Bigger and heavier than stock midpipe, inevitable when you go up in size with everything from resonator to pipe size to cat size. Little to no change in volume compared with stock midpipe, design goal was met...and that design goal was getting us full 2.5 inches of flow all the way from the header outlet (all the aftermarket headers we offer and that I have seen are 2.5 inch outlets), while trying to keep volume as stable as we could in comparison to smaller diameter stock midpipe. If not doing a header, really no point in looking at the midpipe. Even if doing a header, little point in street users doing the midpipe which is only going to help further at the very top of RPMS. We did it primarily for those seeking max flow at all rpms.... the track guys, and for those going eventually with Turbo and/or Supercharger.
