ARCHIVE 100 Series Cat-back Exhaust (2 Viewers)

[sonk76]

Any real world experiences?

This looks very nice.

Does any independent party have any first-hand experience with this yet? Specifically interested in: ease of install, sounds, and noticeable gains in power (ideally on an 06+ VVTI truck)

There are 3 of them out there and on customer cars so far, and we are shipping more out every week. I'm sure someone can chime in soon on their opinion of the exhaust.

These are shipping out about 5 business days after ordering right now. So they're going fairly quick. We'll try to get that time cut down even further as production gets more streamlined.

...what on THIS exhaust makes it almost double the cost of the new DT cat-back exhaust?...

This one sounds like it actually will ship when ordered

As y'all wonder about the experience on the exhaust system, I was the first customer that got the exhaust custom at the first place. I love every moments sitting in my truck listen to that roaring sound from my new exhaust. When the truck start I felt the power bursting trough from the Magnaflow muffler to the 3" exhaust pipe. The original 2"s were replaced with 2.5" in the front and 3" at the final end; at idle it felt like normal exhaust (window roll up inside the truck), but everything change when I put my foot down. It's turn into a different animal especially when it reach 1800s and up. It's muffler music in my ear. As y'all should know my truck has this wind noise from an accident; I hated so bad, normally i have to turn on the radio to overcome the noise, but this new exhaust made a different in my truck. This exhaust system work event better under load, last week I took my boat out to the lake, everyone were checking out my Land Cruiser as it roaring sound came on at low rpm (under heavy load). This exhaust system make it own distinctive noise, it's not too loud or over done like those diesel trucks out there. To me this exhaust system is money well spent and I can't wait for EMS power new turbo system for the 100's. EMS power rock!

What about the silencer option- is there any HP loss? What does that do to the drone at HWY speeds?

And is it recommended to get the "turn down up high before bumper" option if one has an aftermarket steel bumper like BIO, Slee, ARB, etc? Does that option negate the silencer option?

Unless you are making over 400whp the silencer option will not effect power, only the sound. There is no drone at highway speeds with this exhaust, with or without the silencer. For off-road use and maximum ground clearance the turndown tip is recommended. The silencer option is avaliable with both style tailpipes.

since this is tech and not classifieds I will ask my question

When my 80 needed it. I went to a similar muffler and 3" pipe custom routed and welded and installed for less thatn either of these kits. It was a big difference, but I was SC so more air going in.

I don't see the advantage in buying either of these kits vs just having the muffler shop use a larger diamater pipe that is routed per my druthers, welded, backed up by the shop and less money. I am not saying there isn't an advantage, I am just not seeing it. Can you help me understand the advantages of this approach?

Again, not meaning to crap on your thread, but this is tech and I am looking for the tech answer

Stainless steel piping. Stainless steel quality muffler. Tig welded. Mandrel bent. Fitment that is dead on. If $550 is too much to spend on a catback for a 100 series you may as well stick with a factory exhaust. Personally I'd never put crush bends or anything but stainless steel exhausts on any of my vehicles.

One quick difference I note is that the heavy flanges make the system long term serviceable. Most of what I have seen from exhaust shops have re-used rusty flanges and weld new tubing to them. Also, not all muffler shops use mandrel bent tubing and add some restriction as a result of kinked bends. Also the way the merge is done on the stock 100 is abrupt and before the muffler, in the DT and EMS exhausts the muffler merges the left and right cat streams and I think that could be the most significant flow improvement (not that a local shop couldn't do that as well but it is a bit more complex than the straight 6 cruisers.).

The EMS system looks well designed and I certainly appreciate the quality flanges and clamps, I would prefer fewer welds between sections however. It appers the EMS may be built from many off the shelf pre-bent parts (thats how I have home built in the past anyway).

One thing I have not seen presented is tubing wall thickness of the EMS and DT systems which could also impact long term durability especially for off road use.

On the other hand I had a local shop chop in a magnaflow to the oem piping and delete the resonator for <$200 so I'm pretty happy for awhile. The EMS looks like it would flow and last much better than what I have now however. I have not looked too hard at the DT system yet. /end ramble

On the number of welds. This is how our production usually goes with most of our products:
1- prototype and r&d work done with pre-bent mandrel 180 sections of pipe that are cut and shaped to fit the way we want.
2- first few production runs are built using pre-bent mandrel bends that are hand cut and hand shaped to our precise jigs.
3- we have our pipes 3d scanned and each section of pipe is mandrel bent as one piece by a highly accurate computerized CNC bending machine. After this batch is ready then all assemblies going forward are built using the custom bent sections.

Either with the pre-bent mandrel sections or with the cnc mandrel bent sections the quality and fitment is 100% perfect, strength is the same, and longevity is the same. We TIG weld all of our assemblies with 308L, 100% pure argon shielding gas, and all piping and flanges used are true 304 stainless steel.

Andy, you want to split shipping on a couple kits to sunny NW Denver? I'm considering this... someone slap me.

Thanks for the response. Can you expand on your last comment. I see stainless as more long term durable (good thing) not any impact to performance. is that what you mean?

Yes. 304 Stainless steel is far more resistant to corrosion and rust than steel, aluminized steel, or 409 stainless. It makes for a very long lasting exhaust.

SLAP! No can do. My Magnaflow just went on in March, I need OBA and skids next. Looks like a very nice system however!

These are shipping within about 3-5 days of placing your order. They're going out very fast.

Also, we now have a full header-back option available which includes new high flow mid-pipes (the section of exhaust that goes between your header and the "cat-back" exhaust). The new high flow mid-pipes are 100% built from 304 stainless steel with thick stainless steel flanges. Have built in high flow catalytic converters to keep you emissions compliant. Include all of the necessary bungs and hardware to install your factory O2 sensors. Are larger diameter than the factory pipes for even more exhaust flow and more horsepower gains. The new high flow mid-pipe is available for the 1998-2002 right now. And will be available for the newer model years soon.

Oh yeah gurl, you are talking my lingo! Looking forward to the 03+ version...

When you going to tackle the headers and give DT a real run for their money?

 

[PhrogsPhorever]

What converters are you using in the mid pipe assy? Will the mid-pipe be built into the exhaust or set up like the factory cats as a one piece removable item? Will they be Federal (EPA) compliant, CARB compliant, or for "off road use only"? People are gonna want to know

 

[sonk76]

Is this an easy DIY project? How difficult? Any special tools needed ?

I was looking at the bolts that currently connect cats to the exhaust and they are pretty darn rusted. Not sure how much fun it will be to try to get those off... (btw, are those nuts and bolts also included with the kit?)

 

[pip235]

Are pictures available for the headers and the mid/converter pipes? Also price points for these items?
