For 3.0L 5speed what exsust mods do you guys thin are best??
not including extractors and high flow cats though just the best possible normal exhust. i cureently have a sports rear muffler on mine and i'm looking at getting RPW extractors and a high flow cat though what would be the best exhust system??

The stock piping is fine unless you're going forced induction. I'm getting extractors and a highflow cat too. I've been told the stock cat is fine for 200kW but I figured what the heck. I'm going to use the stock piping. It's almost 2.5 inch mandrel bent stuff anyway. Spend your money elsewhere.

I got a MagnaFlow High Flow Cat to complement my RPW Extractors and MagnaFlow Muffler

Can't remember really, I bought 3 MagnaFlow mufflers at that time to try which one fits my rear end (The magna not me) best...

I think I paid 1200 or somewhere around there for the 3 of them..

CHEERS

Is there any difference between the single or the dual muffler?
I was thinking of gettin a single but then the dual muffler looks pretty good on a magna

Yes... I think about 100 dollar difference.... A single tip MagnaFlow Muffler is around the 300 Mark...

Oh I forgot... It's got a V8 Growl.... Deep Throaty.. better than Lukey or Walker IMO..

BOOYA runs a Redback system for the rear muffler, and a red back high flow cat, and she sounds amazing!

next time when ive got a few hours to spare, ill make some recordings for everone.

Mmm, i am a sucker for twin tips!!

Manual

hey im a bity retarded in this section... so is a hiflow cat like the one for sale in AM a muffler? or do i have to get one of those too?
Ive got a VRX and im thinking of getting the extractors and the high flow cat.... if the cat is a muffler, do they come in a single tip thatll fit the VRX body kit?

Cat is slang for Catalytic Converter. It converts nasty gasses into not as nasty gasses and is up the front of the system. The muffler sits right at the end for the exhaust where your tailpipe(s) are. Your muffler is fine, don't touch it. Go extractors, RPW are getting some race spec ones manufactured at the moment. High flow cat wouldn't hurt. One of the guys here fitted a Magnaflow. I think AM sells them too.

ok thanx, so what makes the nice noise :)
is that the high flow cat? and what do you reccomend? Magnaflow seems to be the go from what ive read.

What did you end up doing with the other 2 mufflers that you didn't want? Seems like an expensive way to go?

That was me... it made the car lag at first but now it's all goooood!

Here's a Pic of the mufflers, only the tips were different, 3, 3 1/2, and 4 inch... I sent one home and my friend took the other one...

Nice Muffs there, very shiny. 8)

Not when they are under the car LOL.... :D

aight, where can i get me some magnaflow mufflers??
or the redback ones that booya has??

DUDE! :D

Your local friendly exhaust shop should be able to get one in for ya :D

Go MagnaFlow and you'll Flow with the Growl... I know coz I am Flowing with the Growl... Weeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee....

ok so i'm looking at around 300 for the magna flow single tip....? is that installed?? Might cruise around and find some prices....want to know the price so i can compare roughly the prices.

Also is the twin tip louder than the single by any chance?????

cheers

The single tip will be around 300 not including INSTALL... as for your question about whether twin will give a louder growl.. yes and no..and only slightly and negligable..... very very negligable...

No if the twin tips are split through a single muffler chamber and you have to take into account the materials used, basically, the exhaust note is silenced by it's own frequency.


Yes if the inlet splits into 2 chamber each running their own tips which is like mine in this case.

Hope this helps in your decision.... :D

CHEERS
Nick

yeah thanks mate,
i think i'll be goin for the single tip. then later go with the highflow cat and stick a pod.....that should sound nice aye?

Yup... and remove all the resonators running along the Filter set up and your car will hiss louder than a cobra..... :D

Resonators are to silence the induction noise...

Take out those ugly boxes (One on the front intake(Below the Scoop), two of them are after the filter element, the triangle box on the top of the tube leading to the throttle body and one ugly square one below the tube along the filter setup and plug something in it's place, must be airtight and spray it black to make it less visible.. you unscrew the bracket to remove the resonator boxes... with that your induction noise will HIIIISSSSSSSSSSSSSSSSSHHHHH :D

Talk to KillBilly and MadMagna... they're the ones who knows what's best for you to do it.

For me, I am keeping the resonators in, but I blocked off the entry (For EPA purposes) so the car looks like the resonators are still in...

CHEERS

ok.....will look under the hood to see what is there....
2 black boxes...that shouldn't be too hard to find....

kev

What do you fill them in with?

What do you fill them in with?

sorry mate, what was that??

kev

thought blake said they should be left in,
like if you check in the technical section in AM it says some thinggs bout it

Yeah I dunno about the later models.

I'm not going to argue on this topic as I have a million times before. Instead I'll just tell you what I'VE experienced with this mod.

I removed the resonator boxes in my TR V6, I found a noticeable improvement in throttle response. Other people have had no gains and some have had negative results.

The good thing about this mod is that it's not permanent and can be reversed. :)
I used a holesaw to cut out some MDF plugs and then just siliconed them in the holes. Worked like a charm.

can i remove the resonator myself so my exhaust is louder???

can i remove the resonator myself so my exhaust is louder???

You remove the resonators to make the induction noise louder... in some cars, they actually make the exhaust note slightly louder too.. but if u want a loud exhaust... don't put a muffler in it LOL :p but I rather u not do it... Anyways.... having a loud exhaust is not too good for the ears and EPA :p


CHEERS

so magnaV6Sports are ya saying you can hear the air get sucked in alot more if ya just plug up the 3 resonators ??




http://auto.howstuffworks.com/muffler3.htm

this is of a muffler system but still its a resonator, and sayin its only to quieten some of the engine sound frequencies

Make sure we're all talking about the same resonators!

There are resonators on the exhaust and resonators on the intake.

I'm talking about the intake ones.

does anyone know where i can get magna flow stuff here in perth?
mainly the muffler as AM has the high flow cat. thanx

I give induction noise sans resonators two thumbs up :D
I have no idea whether it affected the power, but it sounds cool :)

Inlet resonators are made by the car manufacturers to straighten the flow of air into the engine, not only straighten but other things as well, they are carefully designed peices... You should leave them on, its worth leaving them on for the extra kw's they allow.

peace

I would remove the two exhaust resonators which are limiting airflow... They will make the exhaust sound deeper, and louder. But they also increase drone..

peace

if ya remove the inlet resonators wont it increase the sound of your induction ??

do i have to get that proffesionally done.. or can i do it myself..

Have a read on a report and a dyno test done on my tech pages. This guy who did these tests is in charge of some part of the Adelaide Uni Mechanical or engineering section.

Yes... I think about 100 dollar difference.... A single tip MagnaFlow Muffler is around the 300 Mark...

Oh I forgot... It's got a V8 Growl.... Deep Throaty.. better than Lukey or Walker IMO..[/quote:5f4ddefb59]

Can i use a 3" cat on my TH magna??

kev

I think the INDUCTION VELOCITY is what makes power. The volume of the air at high speed is better with the inlet resonators on.

yes, the pipes are welded wider, put simply...
or they use 2.5 > 3 converter pipes.

do you want better flow? Its a good idea.

I personally feel that you should leave the inlet resonators in, but as Killbilly said he DID notice an improvment, and it is easy to but them back on, so have a go and see what you notice if anyone is willing, and having other mods to the car like extractors or whatever could have different effects on the car so who knows :?: , but for a stocker I'd leave them in.

I think the INDUCTION VELOCITY is what makes power. The volume of the air at high speed is better with the inlet resonators on.

It's the mass of the air the engine cares about. Both mass and velocity are measured for fuel ratios. Resonators are a tuning feature which helps in small ways across the whole rev range and has an important role at specific points. Apparently it's possible for resonance waves to travel up the induction at specific RPM's to disrupt air flow. The resonator is used to minimise this. Try removing it out and see how your engine goes. That's the only way to find out for sure.

This is one interesting thing that I will go read up on and see what I can find... mmmmm

Yeah, I've got no idea how this relates specificially to Magna's but our fluid dynamics guy said this is what resonators are for and if they are there, then they are there for a reason. But as with all mods, if it works...

I think the INDUCTION VELOCITY is what makes power. The volume of the air at high speed is better with the inlet resonators on.

The peak velocity is higher without resonators.
If velocity is so good, why not use Maccas straws for intakes? :p

Because garden hose is more flexible :D
