We've been listening to the call of several enthusiast that have 2.5" performance axleback exhausts that they do not want to give up, yet they would like a 3" turboback setup. With the soon to be released MadDad(TM) 3" catted DP, and with the recent and popular Stromung 3" downpipe on the market we feel it's time to add the additional pieces to give you a full 3" exhaust system all the way to your 2.5" axleback. We are introducing the MadDad(TM) Halfback exhaust. This will be a two-piece setup consisting of a 3" 3rd cat eliminator just like our current MadDad(TM) 3CE, which means it will have the heatsheild. The difference is that this pipe will not taper down to 2.5", it will stay 3" and connect to our 3" intermediate pipe that will stay 3" until it mates with your 2.5" axleback exhaust(where it will smoothly taper). We will also be putting in a high-quality 3" flex joint to relieve any stress due to the removal of the factory style donut gasket/spring washers. The entire setup will be T304 stainless steel and will come with new gaskets and install hardware as well as the same 14 day money back gaurantee that all MadDad(TM) exhaust products include(and the only MBG of any exhaust products). Retail pricing will be $399. We have our exhaust fabricator working overtime on this one so expect a release and real product sometime mid April. We will be doing a pre-order group buy at $359 to be posted shortly. During the group buy we will be offering special bundles with either a Stromung 3" Twin Dump DP or a MadDad(TM) 3" Twin Dump DP w/Cat(due out in April as well).

Since this is two pieced, are the parts going to have flanges at a similar location to the stock pipes? Basically what I'm getting at is, for people with full length downpipes like an HKS or Invidia, can the midpipe part of the halfback fit with them? I think many would go for it because no one makes a flex jointed midpipe.

It is being developed to the factory locations so yes the intermediate pipe should bolt to most full length downpipes that DO NOT use a donut gasket.

Yesssssssss you guys came up with exactly waht I wanted!!!! I bet you guys were planning this for a little while anyway.

Comes with pipes, gaskets, hardware.. sounds like it's ready to rock and roll. Are you gonna have an option of coating either one of the pipes? Just wondering. I'd take it non-coated for the bling factor. I'm pretty much totally in for this. Need to finish off my exhaust.

Will you sell just the intermediate pipe section so people with a full length downpipe don't have to buy a useless (for them) 3rd cat eliminator?

We we're really designing this to complete our own SuperStealth turboback(when combining with our new 3" catted downpipe or Stromung's 3" downpipe), but the intermediate pipe should fit all those downpipes that use a non-donut gasket setup. Time will tell. We'll have this shipping to us in the next week.

Rich

Any pieces delivered to you yet? Just wondering.. wanted to check out some pics :devil:

EDIT:: Since I seem to be the most avid about this, I wouldn't mind guinea-pigging if necessary ;)

Any updated word on the ETA of this?

Still on track for end of the month but it will be close. There have been some delays sourcing a quality SS flex joint. The first one received didn't look to be very good qulaity so we had to source another, but I think we're still on track for last week of April of first week of May.

- Rich

Bump for my anticipation of this piece.

We're getting closer. Here's a sneak peak at what should be the final product.

http://www.daddysscp.com/nasioc/halfback_1.jpg

Our famous MadDad(TM) 3CE, but in the Halfback setup it doesn't taper down to 2.5", it stays 3", but you'll notice our 3" intermediate pipe makes a small taper where it mates with the factory exhaust or any bolt-on. Now you've got the pieces to build that Stealthback setup that you've been dreaming of. The perfect mate to a MadDad(TM) TwinDump Downpipe w/Hi-Flow cat or Stromung catless DP. Works just fine with ScoobySport and Bosal DP's as well, and the factory DP. Production units will be available by end of May.

I'm lovin' it.

Will this system mount to the stock downpipe?

Indeed it will. Even though it's a 3" system, the flange that mounts to the factory DP was design in such as way that it will bolt-on leak free. The flange that connects to the DP is the same flange style found on Stromungs 3" DP(which can bolt to the factory 3rd cat) or our MadDad(TM) DP available later this month. That's just a long winded, Yes.

Are you taking preorders yet?
Is it $359 shipped?
Any word on the release date?
PM me with a great price that I can't refuse on a half-back and Stromung dual tip axle back :)
Thanks,
Marquette

Hey Marquette,

The price isn't firm yet. I want to hold the pre-order when we do it to $359, but we're making another change that's going to drive our cost up again. The one-off we recently received fit great and works well. In fact my exact setup is our one-off MadDad(TM) downpipe w/hi-flow cat, and this one-off MadDad(TM) Halfback all connected to a Stromung dual tip axleback, but I'm not in love with the flex joint, in particular the inner wall of the flex joint isn't as smooth as I would like. So I've sent a new flex joint to my fabricator to build me another one-off. This particular flex joint is about the highest quality I have ever seen. It has an inter-locking stainless steel liner that makes it almost as smooth as a straight pipe, but it's also about the most expensive flex joint I have seen. I don't expect our Halfback(TM) to be huge selling item. I expect it to be one of those products that a few people are going to love, and if that's the case I want to make sure it's just right and that means it may be a few $$ more but nothing crazy. No matter what the pre-order will be $399 or less. If I can keep it at $359 I will. I'll shoot you a delivered price in another week once I know what the real deal is going to be.

- Rich

Even though it's taking longer than expected, I'm expecting this to be a great product as I've been following it for a while now. Good to hear you're trying to make everything up to par... good R&D = :banana:

We think we've found our flex joint. While the first prototype of this pipe has been working great, we've delayed the release in search of a flex joint that is just a hint better in our opinion. While looking at serveral flex joints during the process of building this pipe, I was surprised how ribbed the inner wall of most flex joints were and I didn't care for it. So the search was on for a flex joint with a smooth inner wall. This is what we're settling on. Look for the full Halfback exhaust to be available end of July.

wow you da man.

any updates?

any updates?

Our flex joints shipped earlier this week(hurray). They should be arriving tomorrow then I have to forward them to our fabricator. I consistantly had to update ETA so I'm going to through out something I think will be real: 2nd or 3rd week of September before I actually take delivery and can ship.

Rich

cool thanks

OK, it's been a while getting our Halfback combo out the door because we were not happy with the flex joints we were finding. We finally got the large shipment of flex joints we needed to complete the intermediate pipe. They are being forwarded to our exhaust fabricator on Monday. It will take a few weeks before we receive the complete product but I honestly feel it was worth the wait to make this the best product it could be. I don't think you'll find any similiar product using a flex joint this smooth(or any similiar product period).

Are you going to offer just the intermediate pipe? I am asking because some of us have a downpipe that it catless as well. I mean, the down pipe is catless and goes all the way back to what would be the end of the 3rd cat. Ie. Helix, Inveda... Just curious as I am in the market as of last night. I have a Forester so even axle backs are hard to come by but I will have that made for me. But I will be running catless as before and need an intermediate pipe that will bolt up to a flat flange instead of the doughnut style. I know I can purchase the Stromung as you mentioned. That was the first exhaust I had on the car but then moved to the Turbo XS set up only to find that it hung down too low and scraped on everything. So, I now have a Helix dp on the way and am looking for a mid that could mate up. Then again, I could have one made but if someone has already done all the work it might be cheaper.

Thanks,

We are making more intermedaite pipes than the 3CE's that they mate to it for the very reasons. So in other words, yes you will be able to buy just the intermediate pipe separtely. Its a little on the pricier side(as far as intermediate pipes go) due to the flex joint being used. Pricing for the intermediate pipe alone is going to run about $229-$239, and $399 with the 3CE pipe. That price will include two replacement gaskets.

- Rich

I am down for the intermediate pipe. When can I order one? Can I be put on a list? The new dp is in the mail and will be here with in the next week. I will probably just wait for the intermediate pipe as I am tired of climbing under the car for now.

The long wait is over. The Halfback Intermediate pipe is finally here. We have the 3" non tapering 3CE to go with it or take it by itself to mate with your 3" downpipe. For the ultimate stealthback combine a MadDad(TM) Metal downpipe with the Halfback setup, or go with a Stromung DP and Halfback setup(Stromung DP exits in the same style flange we use on inlet into the 3" 3CE).

Halfback Intermediate Pipe: $229 thru October, $249 thereafter
Halfback combo(w/3CE): $399 every day
MadDad(TM) Metal / Halfback Combo: $759 thru October, thereafter $789

Here's a long shot showing the full MadDad(TM) Stealthback setup(with MadDad Metal and Halfback). This was from a recent 26 car all Subaru Dyno Day we did with our service partner, KTR Performance.
No that downpipe isn't available(in case your asking).

how can we order?

how can we order?

Halfback Intermediate was just added to the Exhaust category. Just followup with an email stating your a Nasioc member for the $229. Freight will run between $8-$15 depending on zip.

Do you have any dyno of power gains on a stock STI? I can't find any stealthback/halfback dynos on the STI. Nice product!

The Halfback intermediate is too new so we don't have enough out on the street to have STi dyno runs. There are few guys with the MadDad(TM) Metal DP / 3CE combo out there. A couple of them running Cobb Stage 2 that you might be able to ping. Check out imprezawrxsti.com. I have a local STi customer that is going to be picking up the full system sometime late this month. We'll have him hit the rollers to see what he gets. We already know his baseline from this past weekends massive dyno day(26 Subaru's) so we'll have something concreate, but it make take a few weeks.

Could I use this pipe on a stock WRX exhaust?
I am wanting to get rid of the resonator in hopes of making my exhaust a tad bit louder so I can hear the car better while driving with music on, but am not looking to get a noise ticket.

You'll want a Stromung intermedaite instead. I'm currently out of stock. But there $149 plus freight. The Halfback pipe would need the matching 3" flat flanged 3CE pipe to go with it. That combo would mate to your factory axleback and factory downpipe. The reason we call that combo a Halfback is because it replace the middle "half" of your exhaust setup. It would be louder and there would be a real power gain but that would be $399 vs. $149. If you just looking a little volume the $149 is the better option.

Rich, sent you an email from dnidi1@yahoo.com. Want to order the intermediate pipe. thanks, dave

ps. would like to have it before x-mas, planning on doing the dp install next weekend
