Just a quicky, i have a sierra 1.3. it has extractors and a 2" exhaust with hotdog. Will a straight through exhaust give me a bit more power?(it'll be for offroad/comp driving) even if just helping a little, its a gain i need! LOL

Hi there Exhaustfix,
Just wanted to run a quick one by you.
I have a 4.8 Patrol and have just recently put a set of extractor and hi flow cat and exhaust on it. It is still waiting to get a resonator so is very loud but the problem I have is since having it fitted it has ***** the idle.

The motor ...

Hi Exhaustfix,

My exhaust is RS and in need of replacement. It's on a 3Ltr V6 Pajero.

Bitsamissin has this setup
Yep I've got Genie extractors, high flow V8 Guppydore cat, high flow muffler and 2.25" exhaust. It made a noticeable difference.
You need some backpressure so a 2.5" is too large ...

Hi there,

I will be starting a Ls1 into a GQ Conversion very soon, and am having troubles finding someone that can either sell me or make headers that will clear the chassis. Are you able to supply / make such a thing ?

Hi Ross
I have an 85 4runner with a Holden 253 in it. My question is do you know if anyone make a set of extractors to suit? If not any ideas on what i might be able to get in sort of easily? Or if worse came to worse what would you charge for a custom made set?
Matt

hi there you cant buy anthing ...

G'day i've got 1.3L G13A, it has a factory 4-1 exhaust system, i was wondering if it'd make difference after fitting 4-2-1 extractor with the original exhaust system as it's nearly new?

Or do you recommand fitting in sport system for up to 2 inch?

cheers

if it already has extractors ...

I'm picking up a 1995 3l TD surf on Tuesday.

Has stock exhaust on it atm..

Im wondering what the costs will be to wack a decent system on it... Not overly fussed about the noise, I've got extractors on my hilux now that are loud.

Probably run stock boost on it now (may change it later) so would ...

I'm going to have a 3" mandrel system it's on a GQ patrol short wheel base..

Guy at the exahust shop said a straight thru muffler will be quiter then a muffler with a plate or something inside it..

He ...

howdy, is it possible to run a 1HZ turbo intercooled high psi, with a 3" into almost 4" stacks? behind the cab, no mufflers

that may be a bit loud or sound like a boat i think u may need 1 straight through muffler

that wasnt the question ;)

i was asking if it would work, and not destroy the ...

hey exhaust doc,
got a turbo diesel 4.2 patrol with a high mount turbo. got my 3 inch exhaust fitted up today which was all good. however i was hoping for it to be all the way up to the turbo but instead they stuck with the standard turbo dynamics dump pipe which from memory is around 2 3/4 inch ...

Currently building a 1.3l zook and its time to start to think about the exhaust.

Just wondering what size pipe to use ? I will be fitting extractors as well.

Its more a trailer queen that DD so noice dosent realy bother me that much, I am looking for the biggest power gains possible.

Thanks in ...

Hi
I have a 4.5L patrol on dual fuel, what exhaust would i need to get it sounding a little better but not too much droning and a little extra performance? Would extractors have any benifit? How much would a system cost? thanks!

4.5s respond well to extractors and 2.5" system if made right they ...

there is not a lot of room to run a twin so u will possiably have to run a 2.5" single 2 cats 1on each side then into a single large straight through mufflers

ok. final question i think. runing a single turbo on an 8, will putting it on the left hand bank with a pipe joining to the right hand bank screw the valves to bad? alot like the kits they make eg. capa ls1 kit. except with it lined up along side the cylinder bank.

this will not hurt valves ...

G,Day I am informed that a petrol 4 Runner V6 will benifit from Hurricane extractors and 2" into single 2.5" sports exhaust. Then once inlet mods are made a half decent power increase will result.

On the exhaust side do you see anything wrong with the setup above.

Cheers
absolutly not this is ...

what would something like this cost and what gains would i have

cost about #850
good gains all round
more power less heat in turbo and quicker spool up time
