ARCHIVE 100 Series Cat-back Exhaust (1 Viewer)

[Layonnn]

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?)

Yes, cat-backs are quite easy.
I would recommend cutting tools as a just in case depending on how frozen your stock bolts are. Spray bolts with PB blaster and if they still won't release with a breaker bar, i'd cut em off and replace.

Unless you have to cutoff bolts, def. a job to install a catback on the 100.

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?

We may do headers for the V8 4.7 100 series later on if there is enough interest. That is still to be determined.

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

The mid-pipe assemblies will be removable just like the factory mid-pipes. We will have them available with 48-state catalytic converters as the default option and California certified catalytic converters as an option as well.

Installing the cat-back exhaust and/or mid-pipe assemblies is fairly easy. You can do it in your driveway with a socket set in most cases. On occasion if your truck is very rusty some of the old nuts holding the factory exhaust on may get stuck and need some convincing to remove. Even if you take it to a shop to do the install it should be around 4 hours of labor from start to finish.

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

Been a bit swamped here at the shop. I'll get some photos posted of the mid-pipes later this week along with pricing. Pricing on the cat-back exhaust is here: http://www.emspowered.com/storefron...roduct_info&cPath=122_201_202&products_id=757

Using the turned down tip, will the exhaust vapors be able to vent away from under the truck?

Both exhaust tip styles are designed to exit far back enough to get all exhaust gasses away from the truck, even at a standstill.

There have been three rounds of DT header group buys to date, so yeah I would say there is plenty of interest. In fact there is much higher interest for headers since they are a fail point on the 100-Series, where as the exhaust is simply a cosmetic or performance upgrade.

Add in the fact there has been some DT header failures, and you have the opportunity to add a great product to the market! The only downside, is you have to do is twice, one for 98-05, and one for 06-07.

Isn't it 98-05 and 06-07? VVTi.

Opps, you are correct! Typed too fast...

Another one in for install. This one is getting the EMSPowered high flow cat-back exhaust and also the EMSPowered high flow mid-pipes with catalytic converters. Dyno before/after dyno tests and more sound clips will be posted with this install along with more photos for you guys.

Are you going to do a dyno run of:
stock
catback
catback + new cats and mid pipes?

That would be good data to see

Send me an exhaust and I will test before an after on the dyno we used for the DT header Runs. http://tlcfaq.com/main/2011/09/doug-thorley-dt-headers-dyno-results/

Best idea yet!

Btw good job on the header dyno's. Never expected just headers to make such an improvement!

Just got my cat back, getting it put on shortly! Looking forward to the results of the dyno.

Yes, yes, and yes. And we are also installing headers on this truck so there will be one final Dyno of the cutback, midlife and headers as well.

We are already dyno'ing today against a stock exhaust. A Dynojet does not lie. Do you have a dt cutback you can test against?

Shoot me a pm/email if you have any questions.

I don't have the DT but it could be obtained. I'm certain a mudder would loan his for a week for testing.

The point of my dyno runs is that it's an established and unbiased baseline that this community already knows. I have no reason to doubt your results but my 100 is a well known in the community on the dyno topic. The DT estimate of power from the headers didn't hold up in the real world of the dyno but the differences in performance are apparent to end users and I'm certain our Dyno results helped sales for them.

I'm not suggesting this as a quid pro quo but as a value to the interested parties who have an interest. DT is a known factor in terms of build and the headers specifically. It would be great to vet out alternates.

I'm not sure about your Dynojet comment since dynos can be manipulated. As a tuner I would expect you to test with your tools. But every dyno is different and the operator makes a difference.

Where is the results? How about a video showing the exhaust..

 

[RobRed]

I'm interested to see the Dyno Jet results... If I were to speculate the peak difference will probably quite small, maybe 7-8 HP. The curve will be more interesting so numbers alone will be of little use - the full plot is needed.

Dyno testing finished up. Will post info later tonight when we finish up the day here at the shop.
