Hey guys, Im looking to improve the sound of my soarer. It already sounds quite good unmodified, but Im looking for something that will make me smile again. My mechanical knowledge of cars is pretty poor and I have done some research about exhausts. Most people seem to advise a "straight through pipe" is a good option.
helpful, but im still confused by all the terminology etc...
Im planning on going to some exhaust shops this week but I dont want to get •••••• over due to my lack of knowledge. Any tips and advice regarding how I should go about it would be greatly appreciated including how much I should be paying and for what system.

I thought a lot about such exhausts for my old 3.0L back in 2008, I'd like to do the same on my current 3.0L but I tend to avoid spending money on it since my 4.0L Soarer is my actual project car.
Either way, I had this old drawing handy - I think this would get a great sound out of the 2JZ and be quite unique.

Thanks for the response, Ive been following your restoration page on facebook aswell. Would that be a straight pipe set up in that diagram? Also I generally hear most people go for 2.5" on a dual system, any specific reason for the 2.25 and not the 2.5? Also, do you have any idea how much that should run me for a set up like that?

Id actually run 2" on each pipe maximum the stock 2JZ headers are a split type so you could run true dual from those, run an H pipe or two. Could throw two reasonators in if it was a bit loud etc...
Otherwise straight out to the back with some 2" Lukeys would work well, or similar Magnaflow units.
Keep in mind its a 3L engine, one 2.5" tube would be enough, so two 2" pipes on what are effectively two 1.5L 3 cylinders is plenty big enough. It would make for a unique note, have some Porsche like qualities / Daihatsu GTTI Charade from what I could imagine. Depends what you like though, a more classic six sound would be achieved with a single pipe.
Cost wise... varies a lot. If you use mild steel for the pipe work, and standard press bends plus two rear mufflers, $800 ish, closer to $1500 if you went stainless / had mandrel bends etc.

Went into Trufit in Moorabin today. Showed him the diagram and got a quote. 310 for the resonators alone or 650 for whole the 2.25 system (showed him the diagram, thanks). Cats would be 780 extra.
He said he would use a redback system (thought it sounds better), but could go lukey if I want. It seems lukey has been a common choice reading some other threads here.
So I definately cant afford the cats. So would either go for the resonators alone for 310 or the system for 650. It sounded like the resonators was a risky option according to him but he would just be trying to sell me higher. In saying that, it seems like the 650 option is to my liking.
Any thoughts?

Hmmm typical exhaust shop prices!
I get all my exhaust (magnaflow) parts from Ebay, dotcomparts seller does good rates and shipping. Can get all sorts.
Was that $650 for the pipe work as per the diagram ? Sounds about right without mufflers. Your average lukey or similar should be about 200 each or so.
I think you can get away without resonators, but an H pipe joiner around the gearbox area would definitely be the way to go for smoothing out the noise and reducing some of the loudness.

Yeh, as per diagram. He said it would be custom fit to my car. He seemed pretty trustworthy and knew what he was talking about and they have a good reputation but I'll go get some other quotes as well and he said he would match any reasonable quote. I wouldn't know what to buy off eBay, if probably buy all the wrong pieces! Was that h pipe thing part of the diagram? Also I think the 650 included the resonators as well? maybe I'm wrong I don't know, so many terms and jargon.

got the system done today. sounds mint. defiantly feel a power increase as well, very noticeable. Only thing is he put on redbacks after i told him multiple times i wanted to go the lukeys, but oh well, i dont think I'll bother chasing him up on it. If anyone is interested I can record the sound. Thanks alot for the advice Mike, appreciate it. Very happy with the result.

Okay, took a look under the car. Its one pipe splitting into 2, cats removed (he said you are not really supposed to do this), with 2 resonators (i think, they could be cats as he said specifically removing the rear cats i think, implying there are front ones. They look like two hot dog shaped pieces) then straight through to the redback mufflers.
The diagram I showed him were two seperate pipes the whole way which is annoying considering he didnt follow that either. Does it make much of a difference?
Also, is it worth going back and asking him to swap the redbacks for lukeys? Can the mufflers be swapped out easily or not due to all the welding?
The more i think about it, the more I think he hasnt really done it to my specifications.
Ill get a video up sometime today.

Haha yeah typical exhaust guys.
A single section merge is probably better for performance to a very fine degree, it smooths out the note somewhat, only reason I like the dual aspect is it tends to make the exhaust have a more characterful sound, bit more off beat, like some older Porsches due to their exhaust setup.
Hmmm, any specs on the redback boxes he used? They would be pretty similar style to the lukeys but I think the difference is Lukeys, AKA Dynomax is ex USA where as Redbacks are Aussie made or probably outsourced to Thailand or China.
Obviously dont get the full sound quality out of an iphone mic but best I have. Also it is dual exhaust, but only have one showing in the vid. Will try get some pics later.

Here are some pics, hard to see because it has been painted black. You can see how small the tips are. And unfortunately they are welded on so id need to unweld them then put some nice big ones on. preferred the stock tips.

There is defiantly a noticeable smell coming from it. I couldnt imagine it would be too healthy to breathe in. Do those look like cats to you in the picture? Or are they resonators?
