I've searched and read all of the exhaust posts I can find. I've read Cannga's great writeup of Cargraphic and feel like I've exhausted all that I can find.

Here is the question: I have a Tubi available in relatively new condition for about 1/2 the original price vs. buying a new EP.

The EP raves are, as you all know, consistent. Has anyone had both the Tubi and the EP and can provide me with some critical feedback.

The only drawback I can tell for the EP1 is that its not upwardly compatable with a EVOMS 700 kit.

The car is tracked 5-6 times a year, but is mostly a 3x a week driver as my 2nd car.

So, is an EP worth 2x a Tubi?

TIA

 

I have been in the car with Tubi and have also tried 2 other aftermarket systems from other vendors. The sound of all of them except for Europipe (EP1) was "meh" at best. Boring. They also droned. All of them droned except for Europipe. I found it annoying and distracting. I would not consider myself overly sensitive to various sounds and noises but drone from some of those systems would literally drive me up the wall. Tubi probably less than others but rest assured - it droned.

Regarding EVT700... I am considering it as well. I would of course double and triple check with EVOMS but Europipe seems to be the least restrictive of all street legal systems. I could be wrong but the catalytic converters that come with EP systems are larger in diameter and less dense (100cells vs. 200 cells per square inch), thus should flow reasonably well. The Fabspeed exhaust that they sell with their 700HP kit droned like crazy for me. I will be willing to lose a few HP just to save my ears.

Happy Friday!

 

Hey Seth,

I have a tubi on my 997.1 TT and say it drones would be an exageration(spell?)... Having said, I would probably sell the tubo for EP 'coz it's not loud enough for me.

I would say, what ever you buy, please listen to it first as what I tell you might be totally different then what you think it is?

My '91 C2 turbo is loud as it has B&B headers/exhaust/no cats and that's how loud I want my 997 to be?

Hope it helps. Btw, I am pretty content with my Tubi though

 

I'm pretty sure that Alex@sharkwerks felt that the EP1 pipes were too restrictive for the kit. I will have to check on that. Perhaps EP2 pipes are not.

 

I recall that Paul, speed21 had both, and he considered that there was a huge difference.
Unfortunately for reasons that are beyond me, he is temporarily banned.
However do a search on Europipe and you will come across his posts I am sure.

The EP2 has larger diameter pipes, and is slightly louder as well.

 

+1 Drone on Tubi???? I don't hear it and on several occasions I drive in high gears and low rpm and well nothing. I do wish the exhaust was louder from inside the car however I've had friends at my house while I was two blocks away and they were amazed how loud it was under WOT. So not a conclusive response to your ask but as Quick said I'm also content. Good luck

 

EP all the way... I've had, GMG, Tubi, Cargraphic, FVD on my 997.1TT and I can say EP has the best sounding exhaust period w/out any drone.

 

Wow. Thanks for that answer. Do you have "quiet" or "loud" EP (1 or 2)

 

Th two can tubi is the best, there is one for sale on rennlist now.. I had the tubi and the EP1, the tubi was the better of the two, imo. Flamesuit on.
the single can tubi will drone.

 

I have EP on 997.2TT. I think EP only come in one version on the .2 cars. Im not sure how EP on .2 stacks up with EP on .1 cars. May be Stef can chime in?

 

I drove the gen 1 Tubi for over a year, including a trip from Houston to Bringham and back, perfect exhaust no drone.

 

Hi, thanks for the nice words, my humble 2 cents: For a major mod like exhaust, IMHO spend the money and get what you want, or don't get anything at all. The Tubi exhaust is a very quiet exhaust, and has very little low frequency component. An exhaust could sound great from outside, but for the owner, what important is how it sounds **inside**. Unless you want a very quiet exhaust, EP is the clear choice here, even at 2x the price. The discount is not worth if it's not the sound you want. (There is nothing wrong with Tubi sound btw. It is way too quiet for me, but this is a matter of taste; no right or wrong.)

I don't know in what context the "too restrictive" comment was made regarding EP, but EP uses 100 cell cat and among the largest tubing on market, making it among the least restrictive. For sure, it is NOT worse than Tubi, which AFAIK, uses 200 cell cat (anyone please correct as needed). Give EVOMS a call; I suspect they will tell you that both EP1 and EP2 are ok. The only thing less restrictive is catless/bypass, which is not in the running here. BTW, as important as the cell count is the quality of the cat. My understanding, from explanation of a tuner here (AWE), is HJS with Emitec core is considered the best; Emitec happens to be OEM supplier for Porsche. I think both Tubi and EP use HJS, but I am not sure.

Regarding drone, *all* exhausts on the market have had some complaint from someone about drone. EP, Tubi, etc., all have had complaints. Definition varies but since in general this is considered to be the loud hum at around 2200-2800, we adapt to cruise at above that range and the problem ceases to exist. 3000 rpm works out fine because this is where the turbo torque kicks in anyway. This comment of controlling what rpm to cruise at applies to manual cars; for automatic cars, I don't know what the problem will be like and I would caution buyers beware.
Bottom line is spend the money and get what you want on first try because it will save you money in the long run, and try to listen in person if at all possible. Sound clips can be quite deceiving. Good luck & hope this helps.

 

The maximum backpressure will indicate how restrictive a muffler is.
A stock exhaust has 0.44 Bar backpressure while with our 100 cell stage 1 exhaust it is down to 0.18 Bar. Most aftermarket 200 cell 997.1 Turbo sport exhaust which re-use the stock tips have a backpressure between 0.25 Bar and 0.30 Bar.

The Cargraphic exhaust that I've tested had 0.29 Bar backpressure. Despite its higher backpressure the Cargraphic is still a great exhausts and it is loved and praised by many owners.

I've once started a thread about how to measure the backpressure: https://www.6speedonline.com/forums/...kpressure.html
Check it out.

 

I just installed the EP1 on my 997.1. There is no drone. My Porsche actually sounds like a sports car now minus any annoying loudness and the cabin is still quite!

 

We offer just one version sport exhaust for the 997.2 Turbo. Our 997.2 Turbo sport exhaust is quieter while cruising but louder at full throttle compared to both our stage 1 and stage 2 997.1 Turbo sport exhausts.
