Exhaust advice - To what extent should i spend on an exh?

[Vegitto]

[color=#000F22:post_uid4]Hey all, some advice needed.
Am looking at the exhaust side of things but i am not gonna go as far as a turbo yet! Now i was reading the discussion "Where do i start" and Bigmal said "Nothing after the first 3 give you the same
bang for your buck its all <10kw increase and for around $500
each I don't think is worth it."

I got a quote for $1400 for extractors and new exhaust system. BigMal and all, my question is. For this much will the improvement be average, good, big improvement???

What do you guys think?

Also for canberra members where is the best place to go?[/color:post_uid4]

[color=#FF0000:post_uid0]Keep looking. Too much! U can get some decent extractors made up for under $500 and exhaust for same. Try for just under a K. You will not get a big improvement. Theres 2 ways to get a big improvement - 1. turbo, 2. v8. :;): In all seriousness tho, u'll grin a bit more, it does make it nippier, but dont expect to be seeing off HSVs and Rexes. Also expect it to be a bit more sluggish down low, much better up top.[/color:post_uid0]

[color=#000000:post_uid1]I would just do a cat back.
Extractors by design are for higher revs so unless most
of you time is spent above 5k then stick with the stock
headers.Should also reduce your bill down from $1400
to more like $400.

[color=#000F22:post_uid4]Thanks all.

BigMal: obviously i don't know that much on the engine side of things. But i didn't realize for the extractors to really be at their best the engine needed to be round the 5k > on the revs. Thats given it a fair workin.

So u think not to worry bout the extractors and just go the exhaust system. Only cat back though??? Would just this exhaust system still give a decent improve?[/color:post_uid4]

[color=#736AFF:post_uid1]Kitty wants to get that sexy twin pipe muffler.
I have a chrome tip on my existing muffler, but will be too small when the cat back system is replaced.
Rather than replace the existing tip, I will just get another one and have that sexy twin pipe look!

[color=#000000:post_uid0]I reckon the headers (say Genie or HiTech or Pacemaker?) to suit a 1.8L should only be about $350>$450 based on prices I've seen online.

Chuck in a couple of hunred on new 2.25" pipe and labour, and another couple hundred on a muffler and resonator, keep the stock cat unless it's dead (in that case get a hiflow unit of a Comocon that some muggins has ripped off used)

Say $800 all up? I reckon it's doable at just about any exhaust shop in Canberra, in mild steel, not Stainless.

I 've had stuff done at a few different exhaust shops around Canberra and never had a problem with any of them.[/color:post_uid0]

[color=#000000:post_uid1]Vegitto,
Extractors create a vacuum when working to suck out
exhaust fumes. *Great for top end where everything is
moving fast and the gasses need to get out on the chamber
real quick. *However you have something called valve
overlap which is where both intake and exhaust valves
are open and the idea is that the incoming air/fuel will
help push out the exhaust gasses and also give maximum
time for the gasses to get out. *Like letting people out
from the front and in through the back at the same time.
Much faster than doing one at a time. At low revs the
extractors suck out good air/fuel during overlap causing
a drop in bottom end performance. *I have used extractors
on 2 motors a 350chev and a 304 in a VNSS commodore
and I didn't like the loss of bottom end. *In the commodore
I kept the same exhaust only added the extractors and
noticed the difference. *I have not done it to a 4cyl, which
revs higher so probably better to get exact advice from the
others that have.

Hope this helps

Regards

[color=#FF7F00:post_uid0]i think it cost me about $250 for my exhaust and muffler fitted that was tuggeranong exhaust near carlovers. i bought my extractors and cat of lantis. i did notice a bit of difference in performance but yeah down low its a bit sluggish but when the revs are up its ok.[/color:post_uid0]

[color=#000000:post_uid0]I had extractors fitted almost 3mnths after buying the car.

There was a small drop in low end, but the main difference I saw was fuel consumption. I stacked an extra 50km per tanks at least after the extractors were fitted. Now I do alot of high speed driving (ie 100km/hr+) so this probably also has somthing to do with it... when the car is used as a taxi, fuel consumption is vry bad which just proves mals point.

I think with the addition of the larger exhaust, upgraded filter and running premium 24/7, the car is pretty much running as stock, what i gained with bigger exhaust and intake i lost with extractors so all in all i think the car is well balanced.

I could be wrong and im sure those in the know will correct me.
