I had a set of Pacemaker extractors fitted to my AU2 4.0L today along with a high flow cat.I kept the rest of the exhaust stock so i can add the rest after saving some cash$$$...
Now i didnt expect much difference but did expect a little bit.
Should i expect no difference by keeping the majority of the exhaust stock???
And a big thumbs down to the joint that installed them(at Tarren Point in Sydney!!!) i put the car in at 9am and they finished the work at 3.30pm.

It's like a 4 lane highway going down to a country lane - too much congestion. You are not getting (feeling) any advantage because of the standard system. Can i ask why you fitted the extractors first - it's better to do it the other way - system first and then extractors (or the whole hog in one hit).
My EF had the standard three muffler (after cat) system and I have just had that replaced with a 2.5" S/S two muffler system and already I can feel (and hear) a difference. Next will be S/S extractors and high flow cat.

Ok this may sound funny but my mate was buying a set for his VS v8 ute so since i ordered them at trade price through a friend i decided to get a set for myself.
I totally agree its not ideal to go from the extractors to the stock exhaust,and i just purchased a set of 17' XR wheels last week so im rationing my cash :(
Apart from that i was reading old posts about peoples different exhaust systems and there were that may different opinions i wouldnt know which way to go???

Can't complain about getting them trade price. As you say it's not the ideal way to go but when you finally decide on a system - then you will feel a difference.
I like you, read a lot of the posts and i knew basically what i wanted ie fairly quiet, Stainless, 2 mufflers etc and i finally got it done for $550.

Extractors, 17's - if you call that rationing your cash - Shop on

What wrong with your car being finished at 3:30?

Yep you a dead right xr6wgn, it is much better to fit a mandrel 2.5inch system with a single muffler and rear resonator, and then fit a hiflow cat and extractors, or do the whole exhuast at once.

Your exhaust in total is only as wide as its norrowest point so if u get some extractors they are pointless if they are feeding into the standard exhaust piping go 2.5 or 3 inch mandrel bent the whole way (walk away if they want to do press bends)

What is the difference between mandrel bent and press bent???

carazy

mandrel bends include placing a mandrel inside the pipe that flexes when bent but keeps the internal volume the same. Press bent is when they simply ben the pimp over a piece of metal.
Mandrel bent looks like it was made that way while press bent reduces the diamiter (can't spell) inside the tube. Ie press bent 3" exhaust is about 2.3" at the bends while 3" mandrel bent is 3" all the way along

Nothing would have been wrong if they told me it would take all day to get around to it!!!
But when me and my mate both booked the cars in for the same day,they said my AU would be 2hrs but they would need his VS Ute all day.So the plan was for them to start mine at 9am then give me a ring so we could cab it back from Miranda so we would have a car to cruise in for rest of day.
Its a pain having to wonder a shopping centre for hours to fill in time.....
To make it even worse,my $120 quote turned into $410 when they realised the factory cat wasnt going to fit back in with the extractors on!!!!! The end result is a neat looking job so im happy at the end of the day but would never recomend this place to anyone...
