Outer Limits 4x4 Board

What brand of bearings for the rear do you guys recommend for the rear of 92 w/t and part no. and also preference of extractor brand and size and configurations of exhaust systems.Have read alot about 4 into2 into1 etc for lowdown etc etc.
I need a new system as the muffler is on it way out so I thought I might get a bit more go from a new system.Any info would help me decide.
Thanx

i use CBC bearings, but they are all the same really. Just go down to your local parts guy and get whatever he has.

As for the zaust, 4 - 2 - 1's are the Go IMO, and you won't need any larger than a 2" system for the athsmatic 1.3 carby motor. If you do go bigger, all you will do is reduce back pressure and increase noise. Neither of which will increase performance.

Would 2 in make to much noise as in more noise you think you have got more power.Inch and a half ? gives back pressure not too noisey?Your honest opinion, dont wont coppers attracted to me.

I have a 2" Lukey exhaust on my zuk. Has a nice note without being loud or attracting police. It adds a little bit to performance which I mainly noticed on the highway.

standard exhaust on a 1.3 is a 1 3/4". So 2" is not much larger. Besides, muffler design will determine how loud your exhaust is with a 2" system.

Sorry I didnt get back to yous earlier.From what you people have said looks 2 inch is the go and I will sus mufflers from exhaust shop.Thanx again.

sorry if this a bit of a highjack
but will the info you guys posted be the same on a 1.6 efi vit engine?

Read the exhaust thread in General, heaps of info in there.

As mentioned, the noise will come down to the muffler.

My Skyline has a 3" system with an oval muffler and is pretty damn quiet.

My Sierra has a 2" system with a muffler than barely even resembles a muffler and is pretty loud.

The Skyline, with a much larger system and over triple the power, makes a lot less noise

the skyline also has a turbo which acts as a muffler aswell
my mate ran his hj75 turbo with just a dump pipe and that sounded wicked for a diesel anyway
i'm up for a system for the vit as the exhaust manifold is cracked and the cat rattles
so far i'm looking at lukey extractors and old 2.25in AU falcon CAT and a 2.25in turbo muffler i have sitting at home, hopefully it won't be too loud

Run it with 2.25" pipe as well. Should be good but depending on how yiou like it then you may want to add a small resonator as well. It can be added at any time.

Do you understand what effect backpressure has?

Chris, I think that setup will need the resonator.

Critta, 2.5", cat, triple flow muffler was stupidly loud.
Greg's 660 with a turbo, big cat and resonator only is stupid loud and its only a 660(!)

2.25" pipe is much lighter wall than 2.5 so will transmit more sound. I think that a resonator will be required but with a triple flow muffler and a reonator it will sound fine.

2.25" is plenty for a 1.6. A 2.25 system will flow an easy 200hp.

Steve.

Steve,

The 2.25" is as big as I would go with this motor if chasing performance and probably 2" for the 8v. The lwb had a 2" with 2.25" cat and muffler. In the end I added a small resonator to remove a small drone that occurred around 3000rpm. The 2.25" pipe would have given it a bit more but I was looking at the noise issue as well when I chose 2". I think you would agree that it was fairly quiet. A lot will depend on the muffler used as they are certainly not all created equal.
