CatBack/ Exhaust size.

[KBeezy]

nah. I just have yet to see the data saying the stock flow ratings of our cars compared to other setups [img]smile.gif[/img]

And until anyone does any testing, theres NOBODY who can say what exhaust is best.

Currently, the only testing we (the V6 community) have is timeslips and dyno results [img]smile.gif[/img] And you have to wonder. Edelbrock, dynomax, SLP, flowmaster, magnaflow.. Look at the size of the pipes they use...

2.5" all the way to 3" [img]smile.gif[/img] And yes, they say they're for V6s [img]smile.gif[/img]


Edit: Hmm.. 2 1/4" DUAL exhaust vs 3" single. Hmmmm. Lets guess, which one flows more? Anyone care to take a stab.

"Edit: Hmm.. 2 1/4" DUAL exhaust vs 3" single. Hmmmm. Lets guess, which one flows more? Anyone care to take a stab."

Yet again, you fail to understand the information
presented.

Why do I not have dual 3"? Why does 2.25" make more
power?

In otherwords, I just didn't buy the biggest pipe
and stick them on. We selected the best diameter
for best average power in the required RPM range.

I'm pretty sick of people without the technical
background cutting up replies.

I can clearly tell you've never dyno tuned an exhaust. I'm willing to bet you've never had your
car on a dyno, or track tuned it either.

I may as well be writing in Chinese because you
don't understand how resonance tuning works in theory,
nor practice.

I'm wondering at this point if you're just throwing
out nonsence to get me worked up. In any case,
I'm sure anyone with a clue reading this thread
will pick you out of the pack quite easily.

Now you see what I am dealing with tino. There is always one in a group. hopefully what you and I have said here will prevents the other doubters from listeing to tat one remaining stragler.

Well Harlan,

I'm not going to waste my time really. I've got
nothing to lose by leaving this thread.

As for the "V6 community"; more specifically KBeezy:

If you don't think outside of the box, you'll never
get outside of the box.

Here's an easy question for you KBeezy,

Which setup flows best and will make best power:

a.) 2.5" Catalytic Converter 300 CFM, 2.5" intermediate pipe, 2.5" Muffler 400 CFM.

b.) 3" Catalytic Converter 500 CFM, 3" intermediate pipe, 3" Muffler 500 CFM.

c.) 2.5" Catalytic Converter 700 CFM, 2.5" intermediate pipe, 2.5" Muffler 700 CFM.

[KBeezy]

I'm not saying "Run open headers guys! Throw on a 5" exhaust!"

I'm saying: A 3" exhaust on a V6 F-Body will work and give you the benefits of better PERFORMANCE.

You keep arguing points that I am not throwing out. And dont bring up irrelivent vehicles such as your classic Z28. Keep it on topic with the vehicles at hand.


Edit: Also, what vehicle did you get those numbers from as well as what exhaust system?

[Adrenaline_Z]

If you were smart enough to answer my last question,
you would see that it's the increase in frontal
area of the catalytic that is making the extra
power in your 3" cat. back systems - NOT the pipe
size.

More flow = more power. you don't need pipe size
to make power. Larger volume pipes slow down
exhaust gas velocity which increases the pressure
in the exhaust system.

Now you're trying to argue that my Z28 exhaust
doesn't work on the same principle?

Do V6 Camaro's have some special god given attribute
that allows them to work against all principles
of tuning?

Give me a break buddy. Answer my questions, then
I'll answer yours. At this point, you're proving
that you're not up to the task.

don't worry Tino. He doesn't seem to live by the same rules that the rest of the world does. His math and formulas do to equate the same as ours. I wish I lived in his special land of make believe where I could frolic with all the mythical creatures like fairies, leprechauns and eskimos. Maybe then in this wonderful dynamic we to could avoid direct questions and insert our own wrong ideas and have people believe them.

[KBeezy]

So you're saying because your old school carb'd motor performed that way, all motors will? You're saying a standard SBC is the same as my 60 degree V6 and their 90 degree V6s? You're saying a DOHC Ford modular motor will perform the same way? I sure hope not. Every motor is different and every motor has their own characteristics and qwerks. Just because a dual 2 1/4" exhaust worked on your old school ride well doesn't mean a 3.4 60* V6 will benefit the same way.


You can tune pretty much any car to any setup you have. But I know for a fact that tuning a 3.4 (and I mean REAL tuning. Like throwing it on a dyno and maximizing performance as well as adjusting computer settings) is near impossible. Theres only two people/companies in North America that I know can do it. FastChips and RSM Racing.


Yes, I agree with you that the setups you tried all worked differently, but as I said -- ALL engines are different. And CURRENTLY a 3" exhaust on our cars seems to be working GREAT for PERFORMANCE. Just because a 3" didn't work awesome on your old school Z doesn't mean a single 3" wont work fine on ours. People have the timeslips to prove their 3" improved their 1/4 mile times. So no, I dont feel I have to answer your questions. You can take your money and go buy yourself a 3.4 or a 3.8 V6 f-body and tell us the results you come up with for flow ratings and exhaust gas velocity. But until then you are just talking out of your *** using numbers from a motor that is completely different.

[img]graemlins/rofl.gif[/img] [img]graemlins/rofl.gif[/img] </font>[/QUOTE]Laugh all you want but I want to see a 5.4 Supercharged ford motor get the same results as him with that exhaust setup. Wont happen. I dont give a rats *** if a 2 1/4" exhaust worked best for him. Good job! But EVERY engine is different and EVERY engine performs differently with different setups. and UNTIL someone does flow testing on our motors we'll never know how much a 3" hurts or helps performance. We'll never know how much a 2 1/2" hurts or helps either. ALL we have to go by are timeslips and dynosheets. And you cant argue with that.

[Adrenaline_Z]

Whatever, you are arguing against Scientists,
dyno sheets, Magnaflow, etc.

Who the hell are you to decide that a 3" is better
than a 2.5", or 2.25"? All you've done is shoot
down credible information with a bunch of BS crying to save your poor little internet image.

Pipe flow capacity is the same for any engine.
It doesn't matter whether it's a V10, V8, V6, L4!

For what it's worth, it could be gas shot out of your own *** - it doesn't matter. Pipe flow is
not dictated by engine size, DOHC, carbs, FI, etc
IT'S THE DIMENSION OF THE PIPE THAT DETERMINES
FLOW AND VELOCITY!

On that note, have fun with your forum. For those
that are interested in real tech., come and visit

I'll be happy to answer your questions without this
sort of nonsense.

**** me some poeple are dense! You'd probably see
it on the dyno right before your eyes and have an
excuse too.

[KBeezy]

No, I wouldn't. Your pipe velocity and everything is fine and dandy and all. But you're arguing a completely different topic. PROVE to ME that a V6 doesn't gain performance out of a 3" catback exhaust. You still haven't done that.

[HBHRacing]

WE NEVER SAID THAT IT WILL NOT GAIN YOU DILL HOLE. we are trying to tell you that it will NOT work as well as a properly tuned system, and that you can LOSE in other areas other then PEAK HP. That is it. Grow up, read a book, have the doctor remove your head from your rectum and then maybe we can hold an intelligent conversation with you. Until then your hopeless. The answers to every question and remark you have made are IN THIS THREAD. your thoughts are not based on reality, your only hope is to try maintain what ever internet image you think you have. This isn't a popularity contest. This is a technical site. Get technical or get out. Stop giving bad information just because you don;t want to be wrong..


now here will come a reply from him again trying to tell us we are wrong..

[KBeezy]

GOOD! BECAUSE YOU CANT TUNE A 3.4! DUMBASS! I ALREADY SAID THERES TWO PEOPLE IN NORTH AMERICA THAT CAN TUNE A 3.4! AND I DOUBT PEOPLE ARE GOING TO CANADA OR ACROSS COUNTRY TO GET IT TUNED! FOR A BOLT ON IT'S THE BEST WE GOT! DUHHHHHHHHHHH!


Edit: And 3.8 TUNING has only just begun! This is a platform thats still starting to take off! :rolleyes: So quit arguing motors that you still need to learn about! And I never said you were WRONG. I just said "good, but where the V6 data sheets? Wheres the V6 tuning?"

[HBHRacing]

your a moron.. I said it will not work as well as a properly tuned EXHAUST system. I never even remotly mentioned anything about computer tuning. you can't even follow basic sentences. I guess there is no hope of you even coming close to comprehending what Tino and myself are saying then. You have yourself a good day. I will go post and help people that will actualy listen.
