Outer Limits 4x4 Board

hey fella's.. i am generally a rangie man but my mate was after some info.. he has a 98 model wrangler and he was after a set of extractors for it. he also wanted to know if he could put them in himself. does he have to take the inlet manifold off to get the exhaust off and is it a big job.. cheers guys..

I haven't had to pull mine off but according to the FSM the inlet and exhaust manifolds are removed and installed together as they use a shared gasket. Perhaps you can do just the exhaust if you are careful- one of the other guys will chime in. Though get your mate to check that the new extractors don't reduce the ground clearance. There are some extractors you can get which drop too low or go under the sump. Good ones obviously don't. Hurricane is one brand which I recall people saying did not reduce ground clearance.

Yup you'll have to be a pretty good controtionist to change the exhaust without removing the inlet - sorry dude.
There are a stack of brands - but as MattC Said look for ones that follow the factory lines or some other route that won't reduce clearance - some stuopid ones even go directly under the sump
Hurricane or Banks are IMHO the pick of the crop.

cheers guys will let him know. hurricane was one of the options we were looking at. if anyone has a set they can get there hands on would be grately appreciated. thanks

Mate,

I just recently did my extractors on my TJ.


Its a bit of a pig of a job - but it wasnt super hard. You could do it in a weekend if you spent all day on it!

It was quite a simple job - but there are a few tight spots where you cant get your hand into (or out of for that matter) which makes you swear alot! But, other than that... its quite an easy job.


Need any help - let me know!

Cheers

If he is in Melbourne I have a contact that will do a great job for him.
I used the Hitech brand and they do the job perfectly and are cheap.
Install costs hurt a bit as it is about a 6 hour install for a shop.

As suggested you definitely need to get the ones that go around the sump and not under it.

cheers

zzzz,

how much does your contact charge to get it done,

Was thinking about doing this to the wifes TJ, hers is lacking some low end balls. will these help, or just keep it standard?

Yankee,

I bought my extractors from Suburban4wd.com - excellent bunch of people to deal with, and they sold them to me at a reasonable price.

After the extractors, shipping and gasket, i got my extractors for $480. The most expensive part of the install is the install - if that makes sense.



I found they do help a bit - car runs better and what not.

Cheers
Will

If the original exhaust manifold is cracked then replace it. If it is not cracked leave it, the factory exhaust manifold on a TJ is an extractor / header and they are stainless.
In saying that the pre 2002 TJ exhaust monifolds can tend to crack regularly, hence I had a hurricane extractor fitted.

thanx for the advice fat chilli,


what are some performance mods that you guys do for the TJ for a bit more low end.

what diff ratios are available and what do they cost?
