This review is long over due. The crew at EMS offered up a final fit exhaust at no charge and I happen to not live that far from their shop and was able to jump on the offer. Life has been very busy with planning for the FJ Summit but that is now done and am happy to report that the event was a success! Feels good to be back in the land of the living.

Since the install I have driven from Austin to Florida and back then to Ouray, Colorado and back.

Ill stat with a pic of the stock vs the shiny new EMS exhaust:


The EMS cat back exhaust first and foremost is a gorgeous pice of art as shown above. I cant tell ya that the looks improve its quality but it certainly does not hurt.

When I dropped my truck off they asked me how I wanted the tail pipe to exit, I opted for a full tuck and they delivered. From the back of my rig all you see is the stock bumper and tow hitch, you do not see the tail pipe. This came in handy on some of the trails up in Ouray! This may contribute to the cabin noise but without comparison I cant say.

The sound is awesome! First time I started it up I thought it sounded very similar to my daughters Mustang GT. From inside the cabin it is certainly noticeable but not overbearing. If you like your rig nice and quiet then stick with stock. I really enjoy the sound and after two month dont really notice it unless I get on it to pass someone. I also notice it every time I start it up, kinda brings a grin to my face. There are a few speeds that it is more noticeable than others. Between 20-35 in slow traffic it is a bit louder, at 75 on the highway its not even noticeable. Jump on the skinny pedal and a grin will come to your face.....:D

Performance wise, I would say that the 100 series seems to have to work less to get up to and maintain speed. I dont have dyno proof but know the numbers have been posted. In the mountains, the truck did great! I do run a Spectrum air filter, similar to a K&N, which is my attempt to get more air in and the EMS exhaust seems to help get the air out. MPG wise, I thought there would be a savings and that is not the case. Fully loaded I get about 14.5 mpg or right at 300 miles per tank. For comparison, I dont drive slow. Our highway speed limits average 75mph and you just may get run over if you are obeying that limit.

If you are on the fence about this exhaust, I'd say jump on over! I do have a the exhaust tick and plan on having the EMS crew complete the system with a set of headers later this year. Great guys with top quality products get my A+!

Ill try to get a start up sound clip posted soon.
 
Anyone have a price on this unit?
 
EMS went under. It was just a matter of time.
 
Yeah I just figured that out after reading all the other threads about them. Thank you.

Anyone else have an exhaust recommendation that sounds like the EMS?

I've got a complete EMS cat back exhaust system with a never been used muffler. $200 and it's all yours. I'm in San Diego, you'll have to come here to get it.

I don't think there is really anybody out there with a similar sounding setup. The DT setup, while comparable in quality, is quieter than the EMS setup.

If maxse01 doesn't want it, I would be interested. However, I don't see myself making a trip down to California until maybe early next year. Are you doing any traveling up through Oregon any time soon? If I added a hefty chunk of change to the $200, would you be willing to box it up and ship it?

Yes, I am interested. Is it possible for you to take some pics of the whole setup. Do you have all the mounting hardware? I'm in PA, so we would need to work out shipping.
 
Thought I would chime in since I had an early EMS and did all the dyno testing of it.

The system works very well on the 100 and only a couple of issues I came across, and other notes.

- At some point the muffler was changed from Magnaflow to "something" and there seemed to be issues with the "something" falling apart

- The clamps supplied with EMS were a challenge to get a good seal. I would recommend seeking alternates.

- The high clearance exit pipe is cool but makes the underbody resonance really bad. I have the EMS stock exit pipe (and underbody) and it is significantly better on the drone front

- On a stock 100 that the exit pipe will contact the rear diff when the 100 is heavily loaded.

- The EMS is actually quieter (not by much) than the DT

- The EMS makes more power than the DT.
 
Thank you for the info. That sounds to me like the EMS is not worth it and I should go with a Doug Thorley.

Interesting. I don't remember reading that. Did it have the same issue with lifted rigs?

Thanks for clarifying that. I thought I remember reading that the DT catback was louder.
 
Anyone else have their EMS muffler fall apart from the inside out? Mine has something rattling inside it and it's driving me nuts. Anybody find a dimensionally similar replacement?

I also think I need to weld up the crappy clamps that were provided. They've leaked since day one too.

You mean like this? Put on a MagnaFlow
 
Yes!

Do you remember which model you went with?
 
How long did you have it on for before it fell apart? What a shame...
 
18 months
 
Mine lasted less than a year. Went back to stock and I'm glad I did. Of all the mods I've done the cat back exhaust is the only one I've regretted
 
Installed an EMS cat back system on my 100 in October of 2012, roughly 20K miles ago. Mine has the Magnaflow muffler and has been problem free...short of the noise which I've gotten used to. Knocking on wood now.

Likewise, mine is still problem free...also with the Magnaflow. I did put on a Moroso spiral flow to cut down noise, which helps.
