You'll probably find a thread somewhere on the before/after results I believe. Search is your friend

thanks, about an hour after i posted this i went onto DKNE and bought a pair.

wat would u say is a reasonable price for a extractor back 2 1/2 inch system with a hi flow cat, mild steel.

ive had three quotes. 690, 750 and 850.

im in the newcastle area, does any one know of a good muffler place that is reasonable in price as im only an apprentice

cheers

Are you getting them HPC Coated or wrapped? Definitely best to spend the extra and get HPC so as not to corrode the extractors. It does cost an extra $280 or there abouts. Do a google on heat wrap vs HPC Coating to have an idea.

$750 is about the average price for a good quality custom mandrel bend 3" system with a Hi-Flow Magnaflow cat (which is what I have).

For a 2 1/2" catback system with cat I would not pay more than $750! Unfortunately the majority of Jap brand exhausts are 3" so there's not a lot of option for you with a used Japanese cat-back system for an N/A which would be MUCH cheaper again.

Got any particulars on the 3 prices you've had? i.e. brand/model of cat converter? $160 price difference between the lowest n highest quote... would be good to see what distinguishes the $850 system to the $690 system. For $850 I would expect a very good cat converter (metal cat) and something like a oval barrel twin tip, not just a straight through canon.

Can't really help you much on the Newcastle area.

Be sure to post up how you went with the DKNE extractors. I'm sure most people would like feedback in regards to the fitment, any interference with the factory air box, build quality/welds, engine response, improvements to the powerband (eg. how quick it revs out through the flat spot).

I'm not sure how many people on SAU have tried the DKNE extractors as I believe it's only been around a year now since they started making them? In the past group buys had been run with the Coby's so having some results on the DKNE's would be a good resource for others looking at getting extractors done

I payed for the extractors friday night so the money wont be in there account to monday morning so they should be sent by then. says on their site it takes up to 2 weeks

as far as the systems go, the 850 one ( i wont mention shop names) ive herd a lot of good things about him, like he makes his systems really well, all teh welds are perfect and they make a real nice grunty tone. my mate got his vl done there with a 3 inch and its so nice all the way through the rev range, he uses pace's and metal cats.

the 750 one ive herd mad stories about to, he tried to find me extractors, unlike the others, and he sed the 750 would just be the system and cat, he uses metal cats to, pretty sure any way, the mad 200cell/square inch ones anyway, and he'll fit the headers for free.

i think ill go that one, ive herd some of hes jobs, they sound mad. mates VK 350 sounds aweseom with his exhaust.

as for coatings on the headers, i just got flint grey or somethin, was free, ill see if the place does HPC coatin, other wise ill probably just go heat wrappin, see wat happens.

yea im not goin a big 20 inch cannon on the back, i dispise them completly, they should be taken off the shelves. i just want a nice single oval muffler on the back, the 750 guy sed he'll do that too no extra cost. guess ill just have to wait til the headers get here first but

If a workshop does an awsesome job, they can charge for it, and it's a case of getting what you pay for. If your budget allows, go for the the system that you know will be of high quality.

Yeah I'm over canons too...I wish I did get a oval barrel twin tip now, I saved myself $90 instead =/ Turbo conversion at the time was adding up very quickly.

DKNE do HPC Coating, it's $280 extra.

Over time, wrapping will increase the chance/rate of corrosion.

There's a lot of arguments between the two methods on the net. Have a chat to the guy that's going to do your exhaust and ask for his opinion between the two and he'll give the full run down on it.

Basically you want to retain the heat in the headers to help with scavenging the exhaust gasses out of the engine. The more you can scavenge the exhaust gasses the quicker it will flow = more power, or more so for N/A's, improved efficiency and quicker power delivery as you are relieving the restriction. The next best thing you can do after a complete exhaust system is a high flow air filter, ensuring it is shielded with a nice cold air feed.

That's good if he's willing to just put them on for you. I believe it's fairly straight forward, just the unlikely risk of cross threaded manifold studs.

If your factory exhaust was anything like on my R34, the compliance workshop welded the flanges on both sides of the compliance cat ~_~

Just a quick side note,

if your car is really low your going to have to pay special attention when welding the front pipe (between the cat and the headers) as the headers hang low and LOVE to scrape!.. ask the exhaust shop to try mount them as high as possible..

I already have a hole in my headers

it only has factory suspension so i dont have to worry bout that....... yet. thanks for the heads up but

i was thinkin of takin the extractors to work, im a boily, heating them up with the oxy and sprayin them with the heat spray u can gefrom super cheap, a really good one but, not cheap shit. ive been told that works just as good. i wanna do the intake straight after the exhaust but for now ill probably just put a lukey of k&n filter on there.

thanks fellas

got the extractors, the welds look ok apart from a little bit of spatter and some lack of fusion.

i heat proofed them, goin to go down to the exhaust place tomorrow and book her in for the cat a cat back system

[N-DAWG]

Sounds good.. looking forward to the results Post up a vid / audio clip if you can =]

[GTS25_R33]

yea for sure, well the missus will have to, i wouldnt no where to start.

the extractors r "Turbo Tec". wats the goss on them, never heard of these before

[GTS25_R33]

the muffler guy rang today and sed that 2 of the studs in the top front had broken wen he was taken the maniflod off and one in the bottom row.

there was no clearance troubles with the air box etc,

he sed that the bottom flange was about an inch off the ground, hate to be lowered, so he cut it and re welded it in a good place.

will be all done by tomorrow so ill pick her up and put it on the net.

Got the car back yesterday, exhaust sounds good, although the resinator will have to be taken out for a louder note. i recorded it on my fone but it sounds like a tractor cause its distorted, the digital camera doesnt play back sound and i havent got a video camera but im workin on it.

well the stupid the computer wont let me upload it off the fone for some reason.

ahh well, ill get it on here some how
