vz exhaust

mate i wouldnt touch the exhaust not massive gains. Better off spending money on something else like upgrading brakes, hbd pedal set, tints etc.. or get a v8.

 

you could get extractors if you really wanted...but upgrading the cats isnt really necessary on the 6,
the stock cat works fine..

 

a few Kw and a bit more noise from the exhaust.. not really worth it to be honest from a 6

 

my dyno run before and after cats+extractors revealed a 10rwkw difference

 

What are you trying to acheive?

 

Re carts and extractors

Hey mate. I put a cai kit, 2.5in exhaust and a set of pacemakers on my v6 and few weeks later the factory cats were destroyed. They started to make a real bad ticking/rattling type sound. I replaced them with a set of hi flows and am now looking into getting it tuned.

 

A little power gain?

 

With twin 2.5"(WAY TOO BIG), It's worth getting pacies, you may just get some torque back. You dont have the get hi-flows, but it will make a deeper and louder noise.

And a CAI makes intake noise, not much else. Im not biased, i have one. And Fishman is right, you wont feel a big difference in upgrading an N/A v6.

 

Get rid of the twin 2 1/2" and go slightly smaller and you will get back what you lost with the 2 1/2". It will feel like a different car. Adding extractors and cats will give a bit more of a performance gain. It's all perception though, what somebody else thinks is pointless may be worth doing to you.

Having said that, I do a twin 2 1/4" into single 3" that works very well on the VZ.

 

Although it does actually sound pretty nice with a set of pacemakers and hiflo ballistic cats which is wat i have right now on my calais (190 alloytec) sound pretty crisp with the standard catback.

 

@ Not_An_Abba_Fan, how does your system sound and how much would it be delivered? thanks

 

Anyone tried the pacemaker system? I've been looking around for a good exhaust and I like the look of the pacemaker dual 2 1/4" stuff without the rear muffler. Although a few shops have told me that they are too loud (& bloody expensive) and will not fit them because the fun police will come knocking if they do. Which just makes me want to find one for a listen.


P.S. Have been quoted $1750 all the way upto $2900 for a full system. Extractors, Cat's & cat-back. Most telling me that 2.5" from the cats is fine.

 

Unfortunately this system is not a direct fit to the ute, it will need to be lengthened about 120mm before the mufflers. It is $495 delivered.

 

@ Not_An_Abba_Fan: ohk what size pipe needs to be lengthened? i could probably weld the section in there and i have some pipe laying around home, not sure what size though id have to check, also do you have a video or anything of this system so i could see how it sounds? thankyou

 

The pipe size is 2 1/4". Here is one I did a while ago, this one has extractors, high flow cats and the system. Excuse the "special" guys that recorded it...Without the extractors and cats it sounds more mellow and a bit deeper.

 

By special do you mean that It'd sound better if they weren't "special"? Because it sounds a little hollow in the middle of the rev range, then again it could be who ever is operating the throttle too.

 

ohk thanks for that mate but the file wont open on my computer? sorry and my ute has standard extractors and cats so it would be mellow/deep? cos thats what im after a nice deep note
