Chris you are crazy for sure. I was just making a point that neither of their names were near the top... No disrespect intended. I wish they would list the dates on those runs as well.

 

And Back to exhaust stufff,,for a moment..
I wonder if any one came out with a 3'' traditional large muffler type, how that would fair because we are all talking about 3'' X's needed while there is only 2.75'' traditional out there as the biggest diameter..

 

glad u r on board with that
you certainly have the right to disagree and this thread has def went in the direction that i did not anticipate. i posted results of a simple test Tim and I did on my car that i bet my xpipe on.
21-22psi of boost and 6psi of back pressure before the X.
and i posted the article AMS wrote up which was interesting because they saw similar results with 911tuning exhaust. my exhaust had a similar X crossover. his exhaust fell apart and it was blamed on poor tuning and bunch of other reasons except using low quality cat. my car made 650whp thru a catted and restrictive Cargraphic before i switched to an X and made more power at which point i shared the results as well just like i did this time

believe it or not I would have still posted if it was the other way around and his exhaust killed the AWE exhaust.

article pertained to TT porsche and was not posted here. you dont have to believe anything I post or AMS post or anyone else.
ahh so when Timmy says you popped a motor because of poor fueling and most likely too much boost for your stock studs its OK but when I say it you get insulted, tkae it personally and state you want to fight me lol? i dont have a difference with you on a personal level and as far as cars go maybe just a littleeee bit. i have no problem having this conversation with anyone face to face.

and you def should because the 1000$ add a pump kit will cost you another motor sooner or later. run that by Tim through a PM, see what he says.

but its not the worst. i made power when i switched to an X at one point and at another point it started to hold me back. just like it did for several other members here with 1000+ HP cars. i didnt say for everyone to go out and get straight pipes.... that's just absurd.

my motive is the truth and the quest for power. just like there are videos of me winning races there are videos of me losing races. i am never the one to say "oh hey dont post that video".
as i mentioned before this thread got very negative and i knew there would be some of that but that wasn't why i made it. heck when i made it i didn't even know those cats were what they were until Mark posted a pic and I saw that they were poor quality cheapy cats which explains why they would fall apart. im sorry for calling a dog a dog and a cheap cat a cheap cat.... i guess that's frowned upon now a days. Once that surfaced the fanboy army attacked me for fabricating the entire thing which i did not.

says Chad who has absolutely nothing to offer but personal attacks on me and testimonials about how great the x pipe sounds. thanks chad youtube search does a way better job at that. i thought we already established that you weren't willing or able to do any testing so you have zero to contribute to this thread beside flapping.... or any technical thread that doesn't require pom poms.

its not always the end result, its how you get there. if you copy whats been done or if you do it your own way. use turbos that haven't been used/tested , make your own fuel system, work on your own motor etc. you wouldnt really bother with that since you slapped on some 18Gs just like 75% of the board. there is nothing wrong with that. easy, proven way to make 550-600whp. not what i was going for and not what tim was going for. not for what chris powell was going for before either.

narcissism? i am not in love with my self and certainly not with my car. i am always changing things and trying to improve things and make them better while sharing my results with the forum.

yes Markski has done it a long time ago and that where i will give him props where he truly deserves them. he went 9s and that's not easy in a 996tt.

nevertheless what he sells to people will not do what that car did and can be done just as easily with any other setup. nor do i think highly of the quality of his products that i have seen in person and whether you like it or not i can post about it.

ooo straight pipes. shoulda put an x pipe on and went faster

 

? I really think now that the drama is getting more involvement then the technical info on better exhaust stuff and ideas? LOL

 

This would have made a lot more sense 10 pages ago.
Think of it as "good" info sprinkled with added entertainment. John, you keep trying to get the thread back on point with good questions and relevant posts. I commend you for that, but this thread has a literal "multiple personality" disorder.

 

John,

Back to your question about 3" conventional exhausts - this is how I see it...

A 3" traditional muffler drones like crazy and IMO, the sound does not do the 996TT any justice (to put it nicely). The market is very limited for this type of product and the person that would want that product would in most instances, just do 3" straight pipes, as the sound would be similar and the straight pipes are lighter and cost a lot less. Many of us have "been there/ done that" with the traditional designs and got tired of the sound or have not been happy with the sound, as the 996TT is mediocre sounding at best with the OEM exhaust, traditional designs or straight pipes (my opinion). What the X-Flow does is take a relatively bad sounding car and transforms it into a fantastic sounding car, coupled with 100 cell cats and straight thru piping with no baffles, it also substantially increases the performance. Now the customer not only has a superbly performing car, but it sounds fantastic too, which is a great deal of the enjoyment of a performance exhaust for most people and fills the goals for the majority of 996TT owners.

There will always be those looking to break records and for that purpose, a short and very light piece of straight pipe is the best tool for the job. This is clearly the minority of 996TT owners.

I can use any type of exhaust I want, as we manufacture them and I can pick anything at any time and have tried all kinds of combinations and designs, including straight pipes. You will find an X-Flow on my car because I fit the model of most 996TT owners...I want great sound that I can enjoy on every drive and feel proud of - combined with great performance for spirited drives. I do not have a 1000+HP monster looking to set records. If I did, I would run straight pipes and gut the bumper supports, the interior sound insulation, the rear seats, sun visors, engine fan, spare tire, tool kit, etc., etc. and try to get winning times.

I think the reason you don't see 3" traditional mufflers is that a 3" traditional muffler is positioned towards the record seeking type car and is very loud and extremely droney by design, yet falls short of the ultimate tool for the job and ultimately ends up in nowhere land from a marketing standpoint.

 

Thanks for info John.
I do have a question on your traditional muffler setup though. How come you didn't use a balance pipe between the 2 Mufflers? I would think it's a win win situation for several reasons..
Also there is a New X pipe thread now because the Op was afraid to get on here... LOL

 

Well, that's about it for me regarding this subject. I missed my bipolar meds

last night and I get a little "edgy" when not properly medicated.

1/4 mile drag strips and Porsche........lol

 

Something to kill time...

Went 8's almost 8 years ago in a n2o LS1... Think was 4th or 5th in the 8s... Bunch of youngsters that figured out that a 408ci motor with a 300shot and a glide at 3200lbs could do it

I'm not a road race guy... I enjoy the car on the street the track is just for fun... Now when we build another race car we are going to bypass the 7's and go right for the 6's on radials.

 

:-)

John, we did test that and it wasn't what we were looking for, it was time for a new system. So we decided to design a new system from the ground up - we wanted a dramtically improved sound with a modular component type design, various sound levels, performance options and tip options, etc. - it has worked out to be a great decision. We learned a great deal in the process and became better at what we do...and have more happy customers than ever.

 

That makes sense.

I've dumped 60 grand in this 996 since june and I think this is the last hurrah


I will probably buy something crazy this summer. Whatever it is, it won't
require mods....at least not a lot of mods.

 

Thank you for such a thoughtful, authoritative, and well-constructed post. Very helpful to get this thread back on track. But even more importantly, it addresses my situation to a T.

I've got a 3" (100-cell I'm told) exhaust from RPi, perhaps you've seen me mention it before. It sounds great outside the car. Badass, even, at least to me. But what do I know? Anyway, it's once you're INside the car where it kinda sucks. Drones pretty bad - again - at least to me.

So I need to either fit some resonators or other hoolie-goolie to cut the drone, or this kit is destined for replacing.

I need a setup that can handle up to say 650awhp, while sounding aggressive or even crackly when I mash the skinny, but not rattle the wax out of my ears while cruising around main street.

Who's got me?
-V

 

Thanks.

V, We can set you up with a great sounding and performing system and I am certain that you will be thrilled with the end result. I'll PM you or you can either PM or email me with exactly what you are looking for in terms of sound.

Regards,

John

PS - We have replaced a few of those exhausts you mentioned and the owners are thrilled with the result...

 

Well guys this is a Fabsdeed X system that I am going to test against my 100 cell Milltek on the Dyno..
It is 2.75'' like my Milltek but it is going to be catless..I do like their seperate X merge with a small talk window in it...
I really dont think between the big HJS 100 cell cats rated at 350HP each verses the cat delete pipe on the Fabspeed should throw big ringer in the test at my current level..
I just hope it comes by the 15th for my dyno day..

 

OK,,I decided to take my 100 cats off my Milltek and replace them with cat delete pipes I got from SpeedTech..
Only because I want an apple ao apple comparison when do the dyno test against the above posted Fabspeed X system..
Fluid MotorUnion is going to be doing the fabrication to get them to fit my Milltek on Friday..
Who knows,,I might feel a gain but I dont think so? Or it might sound better,not necessarily that much louder?
