exahust systems...im a noob :|

[cracker]

:wave: hi fellas i need help, im going to get a catback exhaust system and i need to know what are the gains of resonator, mesh that go into the tip and stainless steel pipes. i want it to sound good when i floor it

[Encor3]

:wave: hi fellas i need help, im going to get a catback exhaust system and i thought that was the end of it...but then i found out i cud get resignators and mesh grilles for my tip or someshit and stainless steel pipes and i really dont know shit all about that and what is good and what is bad???i just want it to be loud and sound cool when i floor it. help would be greatly appreciated:D

please re-write the above.. and please proof read, it doesn't need to be perfect just alot better than wat you've posted.
splitting up quetions into dot points might help too

[cracker]

yes sir

[lam.666]

a resonator helps reduce the volume of your exhaust as exhaust gases flow through it, so it quietens it down

i dont understand ur 2nd query about the mesh into the tips and the steel pipes

http://smb.net.au/images/catbackexhaust.jpg

this is a typical cat back setup, from the left hand side of the pic the big round thing is a resonator (this is huge as it looks like its a turbo cat back system), then on the right side of the picture at the end you have the muffler, is that your tip with the shiny pipes?

[cracker]

so then i should not get a resonator

[Barge Ass]

Removing a resonator will not yeild any gains in fact I have seen dyno'ed results that actually decreased the power by a couple of horses. If you want that really loud annoying MMMMMMMMMMMMMMMMMEEEEAAAAAHH sound then remove resonator and get a big ass cannon muffler.

sorry i looked at that, and he does not own an integra, how does that link help :confused:

your right it's irrelevant... i double posted coz there was another thread on exhausts it was relevant to like under this one. however his post is clearly aimed at noise reduction. That link i posted also had a possible solution in the end in the form of an adjustable system similar to the X-Force Varex.

The 3 main contributors to exhaust NOISE are as follows:
- Muffler
- Pipe/Resonator combo
- Headers

heres a thread on resonators with some great advice from TODA (Adrian):

and post#22 here shows what a spiral flow resonator is:

to anser the original post then:
Resonator - Has no gains for performance if thats what your thinking, 'proper' ones will actually make a minute reduction. It's simple purpose is to change the 'resonance' of air flow through an exhaust and NOT reduce dB sound per say as most people think. The Hot Dog design is the most common and does just that with resonance change... HOWEVER, spiral flow and baffle design resonators a re designed to reduce dB rating.

Stainless Steel Pipe - is still bling compared to Mild Steel as most aren't actually stainless steel, but rather chromed mil steel.. therefore will eventually rust anyway.

Mesh Trick - I'm guessing you mean the steel wool trick? This only works on a cannon when you have a silencer... you stuff the surrounds of the bit of the N1 silencer that goes in the cannon with steel wool. I know of someone that managed to lose -3dB at EPA with this trick... however that only works if you had the tip on at the time of getting defected.

gg that guy has got it...

i have a plain cat back with a 2" outlet cannon and wish i got a resonator in as my exhaust drones at night sounds good when your in the mood but its insane when your not..... if i add a resonator i wont loose VTEC scream at all will i will just be a tone down from what it is correct?

if u want to emphasise the fact you have VTEC then imo get AEM SRI i dont wanna sound like evry other douche with an intake system, but wow this really makes it roar during Vtec.

[dsp26]

^^thats true... i actually prefer the sound of it over the exhaust

there's also the other part to it. bigger piping may cause an increase in volume, but it also causes a decrease in flow rate which can drop low end response a bit (but its better if you play around with the top end more).
smaller piping has lower volume, but a higher flow rate as its trying to get the same volume of gasses out faster because it cant hold as much in.

im not too sure about the mesh grilles, but im told they were in the ED exhaust systems to reduce sound a bit or something. but they heat up quite a bit and act kinda like having sparkies in the exhaust in that they get hot enough to ignite some unburnt fuel.

thats sort of correct but not really... coz your talking of backpressure which is also a neccesity of sorts..

flow is flow.. the bigger the volume the more IT CAN flow. everyone here will tell you performance is about making everything work together and that is the absolute truth. for exhaust systems, ultimately you want the intake pressures to be around the same as the exhaust pressures (which is a good balance of back pressure and free-flow), which not many performance shops can measure let alone the exhaust shop.

the reason some people get the 2.5mandrel even on a 1.6/1.8l is because of the overall flow POTENTIAL. a good well designed header such as the TODA item will maximise scavenging effect/exhaust vacuum to utilise the flow potential.. same as when you use aftermarket camshafts/cam gear tuning of overlap etc... these things modify the intake pressure, in turn combustion pressure and in turn exhaust pressure.... i personally got 2.5 mandrel on my b16a2 for that flow as i see no point in backpressuring the system and trying to scavenge TQ.. what for on a revvy 1.6l?? i'd rather get mid-top range through cams+gears

same as the fuel system.. increase fuel pressure too much and you reduce flow potential.. instead of your system being able to support say 400hp on a stockish system doubling the fuel pressure would only allow it to support a maximum of 200hp but the needs in fuelling are somewhat met at the time.. just means you can't take it any further.

[dsp26]

^OK to sum that up...
- too big and lose back pressure
- too big and you just add 'flow potential'
- wether you use it or not doesn't matter.. say 200cfm of air travelling through a system capable of 1000cfm will flow exactly the same as a system with 800cfm or 600cfm or 400 cfm if your only utilising 200cfm.. the spread in AIR DENSITY just varies from the size

[cracker]

haha okay so shuld i get 2.5 inch or 3 inch pipes?

[cracker]

and 3,4,5 inch cannon tip?

[nugget666]

im currently looking for an ehxaust to. im just sticking with a 2" press bent system. car is never going to perform. its just purely for sound.

so you got to ask your self performance or sound. see your car 06 civic. its not in the performance car catorgory either ( no offence ). So i'd just stick to what other civic owners of your model have choosen.

[kazam]

so 2.5" or 3" or both to ridiculously big for an auto VTI-L right?

[dsp26]

^^get 2-2.25 mandrel or 2.5 press custom

[johnprocter]

so 2.5" or 3" or both to ridiculously big for an auto VTI-L right?

your sig is gay

[tiksie]

I want to get a canon tip on my EG hatch just for a lumpy sound, do I need to get a full exhaust system or can I just go and get a canon tip put on ? Where can I go and buy one and get it put on at in Sydney ? Somewhere close to Silverwater...

Cheers.

[dsp26]

^^in terms of honda exhausts.. do whatever you want in terms of a muffler like a cannon/etc.... my only advice is to NOT remove the factory resonator.... if you get a catback then get one.

It's been proven now with my mistake on top of a few other peoples... Honda put a reso from factory coz without, regardless what muffler/cannon you get.. theres this freaking buzzing/lawnmower sound that develops... sounds so disgusting

near Silverwater... i rex Bankstown Muffler fit

[kazam]

^^get 2-2.25 mandrel or 2.5 press custom

nah i already got my exhaust system done im just asking the question on behalf of the thread starter

[Limbo]

You jsut need a good resonator, and there will be no buzzing.
My tip.

Find out first what you are gonna do with the car before putting on the exhaust. Once you do tha then you will know what size and what else you need.

Always use a good quality reasonator or you will get loud farty vibrations.
A good muffler if you want decnet noise reduction. The quality of the parts makes a big difference to noise & performance.
O and a steel cat is worth the money.
But generally less noise = more restriction.

[nugget666]

so for a catback on a ek1 sedan. I should get 2inch press bent with a good resonator and a good muffler( not a canon. im thinking twinloop or a normal tip. . and it should sound pretty good.
