Greetings All.

Ok, today I went over to Damien's house to have a chat...AND he just installed pacemakers and a red-back exhaust...he gave is a bit of a whirl...and...

:drool: OMG!! ME WANTS!! :drool:

What do you guys think of a redback exhaust...even without extractors...?

Cheers,

I guess im nearly the best person to answer that for you seeing as you now have my old Sports exhaust system

There is really not much difference in sound between the standard sports/vrx system and the redback. Its growls a bit more but now that ive done it i really don't think it was worth it

Hmmm...Must be the extractors then??

2'5 Mandrel piping straight from catback (no resonators) straight to the Al4-5990.

F*&king awesome

Though i never had a sports exhaust in the first place :redface:
Extractors and exhaust are best option ofcourse, but muffler and piping makes a diff

Pacemakers will get you some good/nice gains, when I installed them on my old ride I saw an approx 9kW gain instantly - even before they'd even settled in and without the ECU having been reset either. :D

I did. I bought a whole redback cat-back system

Then i dont know why your exhaust is only midly louder than a stock VRX exhaust.. Mine certainly growls ALOT more than before..

Yeah its growls more. But clearly someone who went from a base model to the redback system would notice it alot more

what about the lukey cat-back system? which one does everyone think is better, the lukey cat-back or the redback cat-back? im in the process of trying to decide atm..

Greetings All.

Definatly go red-back. After lukey was taken over by walker, thier quality seems to have dropped...Also red-back sounds a little beefyer...

Try stainless if you really want to hear the girl growl :bowrofl:

I personally believe out of the mods that I have done, the Redback exhaust was my best investment... still very happy with it. The Pacemakers were just icing on the cake really ;)

or you could be like me and install a full 2.5" mandrel bent exhaust from extractors back with high flow cat and 3" canon. In terms of the growl, i havent heard many cars that sound as beefy as mine. And performance wise dyno testing showed a huge (about 12hp atw) improvement in power and torque down low (around 30km/h to 80km/h). I'm telling you know the cars pulls so much harder down low, it really pushes you back in your seat now off take off

im not doubting that that would be a good system.. but i just hate the sound that cannons make, they disturb me. Also they are far too loud, there is nothing more annoying then driving down the highway with a cannon on the car.. DDDDDDDDDRRRRRRRRRRRROOOOOOOOOOONNNNNNNNNNEEEEEEEE EE...... they also scream rice

Thats just my opinion though

Yeah its growls more. But clearly someone who went from a base model to the redback system would notice it alot more
Very true.. but seeing as I went from a VRX sports (the same as yours) exhaust, i still think your assumption that it isnt much louder is way out..

My zed has a redback muffler and I have to say it sounds like utter ****. The Z's, even with a stock exhuast have a glorious exhaust note.....but note mine. :(

Add that it's very restrictive. It's missing the top 1000rpm of the rev range (as verified by a exhaustless full noise lap of the block the other week :D ). Now, whether this is just a **** muffler or it's more to do with the previous owner of the car having employed a retarded monkey to weld it all together, I don't know.

Needless to say a new exhaust system is on the cards....and I'll be quite happy to shell out $$ for a quality muffler and quality workmanship.

z's soudn tuff as

Umm.. i dont know how you can compare a muffler you didnt personally have installed (not knowing how it was done or the workshop involved), aswell as being on an entirely different car to how it would normally sound on a magna..

So what was the point of your post exactly?

I dunno, but last time I checked your magnas and my zed used internal combustion engines right? They both burn petrol with air right? Seems like striking similarity to me. :roll:

What's more they have the same cylinder count, and are of a similar capacity. Now your good ol magna donk would be making another 50% more power over the L, so if the muffler is restrictive on my L, then it'll be damn restrictive on a magna. Seems pretty obvious to me.

Now. I do point out that the workmanship in the exhaust is pretty ****house and may be partially responisble for it's restrictivness and ****ty sound.

I also find it interesting that the only property of the muffler you were interested in was it's sound, not performance. Says something. :poke:

;)

sound is all that matters.....

at maccas carparks :P

I have done something a little different on my KR, have used 2 1/4 inch mandrel from cat back, no resinators into a tj vrx muffler. Sound is ok, no drone at all at 100 onwards, city driving does not bother me at all.
I made it myself as I could not justify paying an exhaust place to do what I can do better as I care about my car as they would only care about getting the next car in.

As for difference between the "Z" and the Magna, there is a whole world of difference besides the fact they both have engines, both will perform and sound totally different due to totally different design, induction, etc etc.

Yes and no. Yes, they sound different of course. But no, becuase the way in which a given muffler will change the sound will be pretty much the same. You see what I mean?

For example. Take 1 lovely L26 exhuast note, add ****ty muffler xxx = ****ty sound.
Now take 1 magna donk (also sounds nice IMO), add ****ty muffler xxx = different ****ty sound.

I mean, if that redback muffler on my car can take what should be an awesome exhaust note and make it sound like utter ****, then it'll also make any similar sized motor sound like ****. There's no two ways about it.

...and again...lets not ignore it's restrictivness. If this exhaust system (2/1/4") and muffler chokes my engine (~150HP) down to ~125HP, just think what it'd do to a 185HP + magna donk? See what I mean?

P.S. Love the sound of the VRX exhaust. Lovely note, loud enough you can actually hear it and not anoyingly loud.

you dont know **** rustin

Edit: That was jason signed in as me.

Back in your box! :)

I also find it interesting that the only property of the muffler you were interested in was it's sound, not performance. Says something. :poke:

;)If you had read even a part of this thread, Tonba (hes the guy who started the thread, just so i dont lose you here) was interested in the sound, not the performance. I guess it makes sense now why you posted about a Z sounding crap with a Redback.. You saw the thread title and thought.. **** this applies to me! :doubt:

As for your redback sounding ****ty, the sound also depends on the piping used to the muffler (not just the muffler) and considering the Z and Magna have 2 totally different tunnels underneath the car this will change how the exhaust gases are expelled, causing different sounds out your muffler, piping diameter of course is another factor..

So my point still stands, why post in a thread about the sound of a redback for a magna with an opinion about the sound of a redback on a z...

Actually champion, if you go back and read the thread, Tonba didn't mention sound at all until his 3rd post where he says it sounds beefier than a Lukey. Whether he was only reffering to the sound is another matter. I'm not a mind reader. How about getting your facts straight before you come out abusing people? I was just trying to be helpful, and it get this **** from you? Tonba asked for peoples thoughts on redback mufflers, I've gave my experience.

Now, your point is still invalid, and my point is still perfectly valid. What a redback sounds like on the zed is perfectly relevant to what it'll sound like on a Magna. I've explained it, and if you still don't understand it that's your problem. Go back and read it again, I wont repeat myself. I've posted my experience, and Tonba can choose to take from it what he wants. I'm not forcing him to do anything. Get over it.

Two last points:
a) Performance is mentioned because the sound and the restrictivness of the muffler/exhaust go hand in hand.
b) Piping layout (bends etc) wont change the sound that much.
