The BEST exhaust for the 997TT POLL
I don't think I ever offered anybody money + my GMG for a Europipe, because I bought my GMG brand new not that long ago. I looked at getting a Europipe but I couldn't get anybody to respond to me. I bought the GMG and have been very happy. You may have me mixed up with someone else. As far as I know I have only talked to steverin06 and doc about exhaust. Your welcome to copy and post any correspondence you have about this. I believe my GMG cost more than the Europipe (i could be wrong but that is what I am thinking) or at least the same. I don't think the thread is bad and no need to close. I enjoy reading everybody's opinion on exhaust or whatever.

I apologize my friend.
Back to the subject!
I know we can't judge an exhaust system by Videos but to me this say a lot... I can clearly hear the difference btw GMG & EP1
I will love to hear the GMG in person (anybody in South Florida or DC?
GMG
EP1
Maybe the quality of the video for the EP is way better but can somebody post a better video for the GMG?

Just wanted to clarify something about our switch from the dual to single can design for the 997 Turbo before what you're saying gets taken as truth. The switch to a single can design had absolutely nothing to do with manufacturing cost. It was done for two reasons:
1. The dual can design was essentially a descendant of our 996 Turbo muffler. Many people think there was only ever 1 dual can Tubi system for the 997 turbo, but it actually went through many variations. The biggest problem with that system was that is almost NEVER lined up properly. One muffler almost always say slightly lower then the other. It also never quite sounded "great". It droned quite a bit.
2. Performance. Simply put...we needed to have a cat-less option that we could use with our 997 turbo power packages, along with the standard 200 cel hi-flow cat version. We did a lot of testing here on single versus dual cans and found that with a specific type of exhaust routing in the single can, the cars made more power then with the dual cans.
The Porsche line of exhaust systems from Tubi are really more of a Champion/Tubi product. They don't sell a system until we've tested it and approved. In fact, in most cases the original prototypes and designs come right from our engineering team first.

....well I did try to explain all this to Chris over on RL but he did his usual and got stuck in some self indulgent fantasy that the old 2 can didn't drone and was more expensive to make which I've known for quite some time is total nonsense. If he had any idea of manufacturing and design processes he would have known he was making a fool out of himself with just that comment alone. I believe these fantasies have been creating confusion for buyers and I applaud you for chiming in to educate members about the real truth between these two particular systems.
The other worthy point I would like to make Tom, and please correct me if im wrong, is that CMS has tested its new Tubi single can against most of the systems Chris has been claiming to be better and the new single has been deemed to be superior performing in every way. Could you please elaborate for the benefit of the members the testing and, the competition it was tested against? If you are unable to due to politics i will understand.

No you weren't lucky at all Chris. If the manufacturer CMS and a highly reputable vendor (Shark Werks) says the 2 can droned and was not nearly as good as the latest version then these are the facts, like it or not. Luck has absolutely nothing to do with it. The forums are regularly used for reliable advice and members and buyers expect any information and facts to be reliable and not get misled in the decicion making process with self indulgent fantasy especially when it conflicts with the manufacturers/vendors advice.
Lol. So Elvis has left the building again?

Chris I don't know why you keep pulling the ripcord every time you get called out with facts. I also note Leo is on to the obvious holes in your various claims as well....
I did inform you over on RL how I had made personal investigations into qualifying your claims (about the manufacturing costs and other issues associated with the 2 can) but again you pulled the ripcord as soon as I put those credible facts on the table for the members. It was also much the same thing recently with cannga and his nonsensical spruiking that the correct way to drive the car is over 3000rpms all of the time to escape the "drone zone"...evidently in a desperate bid to excuse the misgivings of his beloved Cargraphic. So, he too has sadly demonstrated to be another member who has a problem with the truth, pulls the ripcord, goes into lockdown mode, makes abusive remarks to the person calling his nonsense out, and calls in the heavy artillary to protect his nonsensical self indulgent fantasies from further exposure. Fact is this car was designed to be operated in all gears and below 3000rpms....and without throwing cels and the likes and to say otherwise is total misleading BS. What users of these boards need is more facts and less fantasy that way they don't get sucked into making expensive mistakes!!

Lighten up guys, there is no such thing as the best, all have some pro's and con's.
Here's the updated list
Beyonce - good performance, expensive
Madonna - old technology, lots of resonance
Britney Spears - has some build issues
Rihanna - head turner, sets off alarms
Lady Gaga - noisy, good marketing though

Thank you Tom.

And as for the second part, yes...the single can version was tested versus the old Tubi dual can as well as a few of our competitors. No, I will not tell you which ones. As policy...we sell our products based on their own merits, never on the shortcomings of our competitors. The reason we tested versus the others was not for bragging rights, but to make sure we were making the best performing exhaust possible to complement our power kits.
The Tubi Street and Race systems meet each of the criteria we aimed for during testing....sound, performance, fit/finish and overall quality. But still...people have different tastes and expectations of their exhausts...that's why we have so many choices.

Well keep in mind that everyone has their different expectations and tolerances, so it might very well be that Chris' system did not drone. As I mentioned in my post, there was more then one version of the old dual can system so it's quite possible he had the good one.

So just to get this straight are you saying there were inconsistencies in the manufacture of each individual dual can system? Or, just an inconsistency between user experience with the droning? The understanding i was left with from our earlier discussions was that all of the earlier 2 can versions droned and none performed to the level of the newer single system which was designed specifically for the 997tt.1 engine.
Also lets say there was inconsistency between the earlier systems how was it then possible to properly evaluate the old 2 system against the new single? That said then there would be the possibility the older 2 can out perfomed the later single in both drone and performance?

Good circuit breaker Stef!

Initially, remember the two main issues, fitment and sound. We revised the mufflers in an attempt to fix the sound issues, but we still had the fitment issues. The sound was better...but some people thought it still droned. The fitment was still crap..lol. That's when we said "ah screw this dual can design...we need to build a race system without cats, and we know the single can is going to work better and fit better, so let's go that route".
We know that the single can performed better then both dual can versions because we had both versions here during testing.
No....what I'm saying is there were two versions of the dual can system.

The latest 2 can system did drone less then the 1st version of the 2 can....but not in comparison to the single can.
Hmm. So anyone looking to choose between one of these 2 systems would be far better off in every solitary way with the new single?

Edit forgot to ask if you had any comparative data between them to quantify the actual gains and other improvements?
We do have comparative data...but I prefer not to post it to be perfectly honest.
