Hey guys, have any of you got a photo of your car with the coby extractors fitted or any other type for that matter. I'm fitting a camber kit next week and contemplating whether or not to lower it at the same time or leave it stock to allow for the extractors if they hang low. I need to be able to get up my steep driveway

ive only seen pics of them , and i ,m not real keen on the design , no 6 pipe looks like its 2nd bend is too tight also same on no 1 pipe . they are not tuned length cos the front pipes look a lot longer than the rear ones . the primaries are 1 1/2 ", looking at the size of the rb25de ports they should be 1 5/8" primaries . i,ve had a quote from a business called GONZO PIPES , he makes the best , does lots of race cars , but will cost around $900 and that was with a tuned length megaphone for racing ... i got pics of the coby extractors if you want

If you've got a pic of the extractors fitted that would be great, otherwise i've seen a pic of them in a catalogue. I may be wrong but they do look a bit dodgey. Wrapping them in exhaust wrap and the red paint flaking off doesn't grab me either. I'm in Melbourne, are there any good exhaust places that would do a good job for a reasonable price?

Hi Guys,

Yes the Coby extractors are "dodgy", but they are good value for money.

They're cheap - not a lot of engineering could have gone into them.

However, we know they smooth the power and torque curves of the engine, improving drivability. The engine feels a LOT more torquey at lower revs and pulls well from about 2500rpm.

For me it was so noticable that on roads I drive regularly I could use 5th where before I had to use 4th.

So while they are definitely not optimal from a performance point of view (as dondesoto showed us), I reckon they do a great job for the money.

Cheers,

Greg

Thanks for that greg, i think i will just go with the coby's, so you think ordering them from partsco is the way to go? How long does it take and what do you recommend as to fitting them re the paint flaking off etc. Shall i strip the paint beforehand? Have you lowered you car or dos it still contain the stock suspension. It just worries me a bit if they're goign to be dragging on the road after lowering! Or going over a speed hump. I have lots of speed humps where i live :)

Cheers!

PartsCo are the way to go. You pay New Zealand price, so save a bit of money as well. If you can be bothered, I recommend stripping the paint and then either wrapping them in exhaust wrap or painting them with a suitable high temperature paint.

My car is stock ride height and I've never had a problem with scraping. I'll take a pic to show you how low they hang, if you'd like!

Cheers

Greg

2500$ for extractors only!?!?! $2K will get you a full(dump,front,hiflo cat,cat back and muffler) exhaust. not even 2500 for a full NA exhaust sounds believable, unless you gain like 30rwkw from the extractors alone. not saying i dont believe you Greg but that price is outrageous

although im a fan of buying 'proper japanese aftermarket gear' such as trust, hks etc due to them having alot of R and D, if a quality product cannot be obtained then custom is the way to go. custom tuned length non restrictive extractors could see as much gain as Fujitsubo extractors.
