this is a question to all dont get pissed at me if its been asked before but wat sounds better on a 98 magna altera a 3 inch cannon or a 2.5 or wat ?

Depends alot on the muffler etc that you choose to use also ...

Lukey Ultra-Flo sounds pretty good from what i've heard and also gives quiet good performance gains too!

Lukey Ultra flow! I have and is very nice. Not overbearing but you know theres something there.
Cannons are too drony.... Believe me, though it is personal choice in the end.

Yessssssssssss!!!!!!!
My ultra-flo is niceeee!!!!
go 1 orf them man!

How much is the ultra flo installed??????

Yeah Lukey Ultraflow i got one too.. cheper and better then cannon... and ya get guarantees etc... give nice power gain for only $150ish and in my auto it holds power longer and revs further. is quite loud.... i'm considering a little sound deadening in my boot or behind passenger seat just to shut up those who i drive that don't like performance car sound.

the lukey ultra flow sounds good....are the ultra flos loud and droney or just nice n loud?...would an ultra flo be louder than the LRxxx/ALxxx?

i spose it ill have to try the cannon if i dont like it ill change it ill learn from my mistake but thanks for the idea for the advice on the ultra flow ill have to decide but thanks

and another thing is a cannon exhaust is very sexy :D

and a 3 or 4 inch tip on a Lukey muff isn't ????

For 400 dowa you too can have the same exhaust as myself.

SUPER high flow cat, resonator behind that, high flow muffler behind that. All 2.5 inch. All from Redback (except cat).

Pulls adequately until 3000 revs. Then away she goes. With the extra breathing she hauls ass. Looking at getting the cams done to take away the lag before 3000.

Sounds nice, looks like a standard exhaust (mine dumps into the ground and hides behind the rear bar) and DEFINATELY adds to performance. Extractors next. See how much of a difference they make.

you have upgraded your advance into a Sports model exhaust package now, ^_^.

I did that too, I have pacemakers also. But I think your 3.5 will pull better than my 3.0.

What would be the quietest way to install a high-flow muffler then? i'm not a big fan of exhaust noise.

with a higher flow exhaust you're definitely gonna get more sound both on the outside and inside of the car. that's why you can see the stock muffler does sap a fair bit of power to deaden that sound. like most of the folks on this forum i am using the lukey LR2779 (or something) and from what i have read here, in terms of overall cost, performance and sound, prob the best. it's cheap, frees up a handful of extra kW and isn't too loud inside the cabin. and oh yes, gotta love that soft low purring at idle and nice airy sound at high revs. Highly recommended!

The LRxxx and ALxxx ARE ultra lows muffs, thats just their model codes :D

damn, my bad...comes from too much surfin on teh Lukey website :D

does the lukey make a nice noise when it idles or wat ?

(wat is meant by drony)
:?:

i dont believe people prefer sound and looks over functionality!
well whatver floats your boat i guess!

Agreed - ive got this redback full 2.5" Mandrel Bend system from the cat and its great.

OK, so i can tell that the Lukey LR2779 seems to be popular and an all-round great way to go.. but is there better for a few hundred more? Price is not a huge issue.

Ok then so if the the LRxxx and ALxxx ARE ultra flow muffs as you say, does it then mean that the Lukey Ultra Flo muffler is the same as the LR2779?

To make myself clearer, I've included a picture of the Lukey Ultra Flo (Ultraflo.jpg) and the Lukey LR2779 (lr2779.jpg)

Going on what you have said, these two mufflers are the same, as they are both ultra flow. Please correct me if I am wrong.

If price isn't a huge issue then from what I have seen a Magnaflow single tip is around $300 and a dual tip is around $440.


(wat is meant by drony)

What I mean by 'droney' is what Lukey refers to as cabin 'boom'.

(For those who can't be bothered with the link)

Exhaust Drone

Drone in the exhaust is due to the engine driving the exhaust system
at its resonant frequency. You can't get rid of it, any length of pipe has
a natural frequency, but you can change the frequency (RPM) it happens at.

Stock exhaust systems are tuned to put the resonant frequencies outside the normal RPM range the engine is run in. Sometimes they add resonators for this purpose. To raise the resonant frequency of a system, shorten its length. To do this, you can try tail pipes that exit by the wheel or you can try a muffler with a shorter internal flow path.

If you have a true dual system, you can change the natural frequency of the system dramatically by adding a balance tube. If you can't shorten the system, then you can add slightly less than one wavelength of pipe. This will also raise the resonant frequency of the system. The wavelength in a single converter system (not true dual) is a little less than three feet at 3000 RPM. Shortening the system by a foot or so will move a resonance at 2000 RPM to about 3000 RPM.

To move a resonance, calculate the wavelength at the RPM that gives
the resonance you want to move. Then calculate the wavelength at the RPM you would rather it be at. The difference is the length of pipe you need to add or delete. Add to lower the RPM, delete to raise it. If you want to raise it but you can't cut any pipe out, then add one wavelength of pipe minus the amount you calculated. This will have the same affect. If youadd or subtract a multiple of a wavelength exactly, you will not change the resonant RPM.


Wavelength = 1100 X 60 X 1/RPM X 1/4 X 1/2

or

Wavelength = 8250 / RPM

Wavelength = standing wavelength
1100 = speed of sound in air in feet per second
60 = convert RPM to Revs per second
RPM = RPM
1/4 = four cylender firings per revolution (make this 1/2 for "true
dual")
1/2 = standing wavelength is half the wavelength of a "normal" wave

But isn't the Magnaflow series a lot louder than the Lukey?

What would be the quietest way to install a high-flow muffler then? i'm not a big fan of exhaust noise.

Well, I can't really tell you the difference between a Magnaflow and a Lukey, because I've never heard either of them, however I would assume that neither muffler would produce excessively stupid amounts of noise.

I'm currently looking at mufflers myself, I think the best advice for a quiet high flow muffler installation would be to rock up to your local exhaust place and ask a few q's, work out what's what 'n what your options are ect......it's what I'm gonna do. I say this because everyone has a different opinion on 'quiet'. I understand that you are not a big fan of exhaust noise, (nothing wrong with that). I don't mean to appear to be rude but don't be put off a nice sounding muffler...it won't sound like an excel running on only 3 cylinders!

cant u get a lukey because its only the pipe and shove a cannon on the end of it ? wats would that be like it iut could be done

can you explain yourself a little further...I'm afraid I don't quite understand what it is you're asking :(

never mind then aye :)

when i got my muffler, i told the guy i dont want noise, just something with a bit more flow....i told him that lots of people get the Lukey, and Magnaflow......and he said that there are alot more cheaper alternatives that will do the same job, the only thing u wont get is the brand name.
I ended up getting a muffler from there, i dont even know what brand it is, but its a 14" glass pack hi-flow muffler. Does the job, sounds good, NOT LOUD, which is what i wanted. and with a 2.5" CAT back system it only cost me $220 fitted.......

I have definately notcied a differnce, with the car revving alot easier above 3000rpm, and it has also got rid of a flatspot i once had at 3800rpm.

It basically comes down to whether u want a brandname for more money, or something that does the same job for less....

you want drone?? get yourself a DRFT titanium cannon!!!! its great!! you can barely hear yourself think, but from the outside, it sounds like you've got a supercharger!! oh and the cops like it too.... (EPA tested and proven 98 Db) :cry: :cry:

cheers for the advice!
Just to be different i might go a Magnaflow. Everyone seems to go Lukey.

That is correct, ultra flow is just what they call their series of straight through designed mufflers. Different models cars would use different models of ultra flow muffs to suit their car. The pics will look slightyly different because one of them has a different (black) finish then the other. Don't bother touching the pipes unless they're buggered or your planning to turbo, cos (presuming you got a 3rd gen V6) they are already 2.5" pipes . That cat convertor isnt that restricting anyway so its just a waste to replace it unless it's broken. All you NEED is a good high flowing rear muff. Magnaflow, lukey , remus and x-force all make straight through models that would fit a V6 magna the lukely is your best performance for your dollar and the others really wont give that much more power (if any) to justify they're cost x-froce might be cheaper i dont remember. Go the lukey and keep the money you saved to go towards a good set of extractors or POD filter and CAI, which will be much better then just one expensive rear muffler.... hope you read all that.

The stock pipes are are 2.25" which i dont think has proper mandrel bending. If your planing on do extractors/pod filters etc i would spend a bit more (another $150-200) to get rid of the restrictive stock resonator/hotdog in the piping between muffler and cat.

stock is 2.25" mandrel bent

stock is 2.25" mandrel bent

I thought it depended on engine size?

i'm pretty sure all 3rd gens have 2.25" mandrel, regardless of engine size.

i'm pretty sure all 3rd gens have 2.25" mandrel, regardless of engine size.

third gens have 2.5" mandrel bent exhaust. the 2nd gens have 2 or 2.25"
press bent exhaust.

OK I think TEs have 2.25 mandrel (how can have a not properly bent mandrel bend? do you mean it's faulty from the factory ?) TF + have 2.5 I THINK, not sure. Changing the resonator will alter the sound of the exhaust , even with a stock muffler. Dont think too many ppl here have changed it ;you might have to find out for yourself what that would sound like :?

Anyway how i can get my car sounding ricy....not droney or beefy?

--Tonba

Well if all your after is sound and money is no issue then a remus or magnaflow 3 "DTM with a new resonator will get it sounding pretty good. But thats more of a race sound then a rice sound? Why do want your car to sound ricey? Isnt that just all show/sound and no go? If thats really what you want then maybe a turbo smart cannon muffler , they're not too droney in general although i havent heard one on a magna before :? Try to hunt down "braez" or something like that and ask him what he's got, he has a nice big cannon muff on his car and it sounds pretty good prob has good flow too :D

Well, I measured mine with vernier rule or whatever and the outside isn't even close to 2.5. It's widest point was 2.2 and got down to 2.1.

it's indeed sad to hear that some Magna's CAT back is less than 2.25" diameter. If you really need flow and lose on bottom end torque, then you could go 3". Other wise, 2.5" is pretty good for a mid-mild high torque.
No less than 2" though, that's really losing power then.
