I was advised against cannons due to noise levels. The installer recons that with Lukey, redback or magnaflow conventional straight through's I shouldn't need a resonator unless I increase the red line on the engine.
If you let the installer know that you may fit resonators later, he can put a flange after the Xpipe to make the resonator install a lot quicker and cheaper down the track.

made an appointment to go get mine tested today. turned up ad Daadler Exhaust at 210 Plenty Road preston and they told me i had to wait an hour and a half as the equipment wasnt there, So you just lost my future business boys! Oh and wasted another afternoon of my life, so thanks Daadler, EPA and Voctoria Police, I love you all!

Picked up the car this arvo. All up $1255. Headers only took the installer 5 hours. Bloke really knew what he was doing.
Pretty quiet at idle and light throttle. Barks when booted under load but quiet when gunned unloaded. Unloaded from the drivers seat the engine makes more noise than the exhaust. Don't hear burble until you get to the back of the car.
Will find out how she goes at high RPM on the way home.

The original toyota cats are worth keeping, only *substantially* bigger (and more expensive no doubt)cats would be better, i had Carsound ones on mine as part of compliance and they were - inferior construction to the toyotas and wouldnt seal properly.
And yes these were the equivalent ones to those featured on Planet Soarer...

One man. Dropped the car off the night before (Toy's muffler at Redcliffe). Bloke started working on it at 8, had both manifolds off and one side header bolted up by lunch time.
He may have taken the back section of the exhaust off the night before but I'm guessing that would not have even been an hours work.

Anish,
I wanna upgrade my exhaust too but now i just want to change the stock rear mufflers to the Lukey Stainless Steel UltraFlows and later get the headers done..
Do you think is that any improvement just upgrading the rear mufflers??
Or start saving up and do the whole package later on..

Not sure about just doing the rear mufflers. I did got the whole lot in one hit. If you look on the dyno library on planet soarer there are cars making good power with cat back system.
For the cats back, it should only cost you about $450-$600. If you're going to get Stainless Ultraflow cans, you may as well get the race magnums which are a welded version of the same muffler. The RRP is $195 installed so you'll probably get the cans for $145 each. The steel ultraflows were about $115 installed.
With the full exhaust I notice a lot more grunt down low. The car is a lot more responsive off the mark. Havn't had a chance to stomp on it yet.
If you get cats back, you can get flange installed on the Xpipe towards the engine so that only a small section of pipe has to be removed to fit the extractors and relocate the cats.

Guys, I brought my car in 2000 and had it complied as i was the first owner. Back then i had the exhaust done in the compliance as part of the compliance requirements are to replace the stock cats. I hear a lot of comparisons made to the original or stock cats ? are you referring to what was on the car when you brought it? Because they are not the original or factory cats. The reason the factory items get changed is because they flow to much and therefore aren't good as far as emissions are concerned. The true factory units will flow more than any of the same size brought of the shelf over here, though it is illegal to use them !
On my car i replaced from the cats back with 2.5" high flow cats to join into a 2.5"x10" long resonator which split to 2x 2.25" pipes all the way back to where the last pair of mufflers were and had them replaced with to 2.25" high flow units. The complete system was mandrel bent. Whilst i have never had the car on a dyno, i couldn't say properly what the performance difference was though i can definitely say this. The of the line punch was slightly punchier and seemed to most noticed from mid to high end. The note is awesome. Coupled that with my custom intake, the car sounds like an F1 car. I have read many of articles on the standard headers that have claimed despite what many say, they floe respectively well. They really don't need to be touched unless your looking to do some serious work.

Many cars, mine included, still have the factory cats after compliance and have a single new cat fitted in place of the resonator. As far as I am aware the only requirement is that new catalytic converter(s) are fitted. There is no reason why new factory cats could not be used except the prohibitive price. From an emission point of view the practice of fitting one new cat at the rear is the dodgy one. A catalytic converter in that position will achieve nothing from an emissions standpoint BUT it is legal, and cheap. That's why they do it.

Mark, This may be the case ? I am only commenting on what i have been told by my complier. Appartently he claimed that part of the compliance was to change both the cats, reason being that the original cats flow much more than our product available to us and in turn don't play as efficent role in the emissions side of things. He finished the sentence with aske the exhaust guy if you have the old ones and have them placed back on another time. When i asked the guy at the machine shop for the original items he replied with near the same words and stated it was illegal for anyone to fit them so they will be of no use to you. I left it at that. This was back in 2000, maybe things have changed ?

I think your complier was having a lend or didn't understand the rules. The bit about flow is about right; the factory cats are good but that's not the reason for changing them. As far as I can tell it is simply a bureaucratic decision with no real technical input, just the misconceived notion that new cats are good to have, otherwise there would have been some requirement to have the new cats up close to the exhaust manifold where they can actually perform their job. Instead there is just the requirement to have at least one new cat which many compliers fit down the back of the system where it can never work anyway as it won't get hot enough. At least in this case the originals are still fitted and doing their job. This is the cheapest way so was done by quite a few places as it also requires the least labour input. Some compliers actually tried to do the right thing and fit two cats up front after removing the standard ones, much more expensive and if cheap cats are used a bad result for the end user (you). A very few cars were complied by fitting brand new factory cats; the best way.

My car was complied in July 2004,when the extractors were fitted, they found that the original cats were still on the car up near the manifolds and the new compliance ones fitted further back. Cheers
