Not much, and quite the opposite

a) Cobys arent flash, theyre press bent so arent terrific. But ok for the price you pay.

b) As a general rule
4-1 = Higher top end
4-2-1 = more bottom end

Cobys are 4-1

c) They arent tuned length so arent outstanding on a stock motor

d) They dont have a hole for the O2 sensor, so unless you can fabricate something to fit that in, it will run worse than when you began.


Also, how do you plan to connect them to your existing exhaust? Youll need a hacksaw to cut the existing exhaust, and a welder to join the exhaust and extractors, if ya cant do this youll need to get a muffler shop to do it. It WILL be loud (very loud) driving it to a muffler shop with just extractors.

Well, I have no idea, how about you elaborate a little bit more?

[RickGT]

well i rang up my local garage and they said we can get coby or rage, she said the rage 1s are usually more expensive so im guessing they prob bit better, any1 herd of this brand. what other extractors are out there for 4age?

Do some research yourself and find out, if you searched you would have found out that one of your best options is standard 20V extractors, slightly modified to suit. Or even better save the $200 and leave the stock ones.

Also you dont need a new thread on wether to go 4-1 or 4-2-1. I outlined it for you above and its been covered many times before.

Have a search.

Do a search on coby extractors. In my experience the FWD 4age ones are absolute junk. shoddy workmanship and not tuned/dyno tested or anything. put some on my fx and lost power. DONT DO IT

Perhaps look into a factory 20v manifold.

Just a side note, Most coby extractors are painted red, that paint flakes off a soon as they get hot, looks real untidy. It Pays to burn off with a gas torch prior to fitting and repaint with some high temp stuff like vht etc....

just my 2c

I have a set of blacktop headers for sale...already modded to suit a 16v 4age...complete with 4-2 and 2-1 sections...
