soarer v8 stock exhaust system

[UZZ30]

discovered a while back how ridiculously resrticted the v8 soarers exhaust system is so thought some might like to know about it..

Starting at the rear theres two mufflers, then further back theres another two similar mufflers and then the two pipes come into a Y pipe and go into a resinator muffler. Thats a total of five fricken mufllers!! No wonder its so quite!!



After the mufflers it splits into two again, goes into 2 cats and the headers, all that stuffs ok and flows alright.

So once i have my soarer (ive found one to buy) by the end of the month/ early december ill be removing the five restrictive mufflers and fitting an X pipe and at the end dual 2.5 lukey mufflers. Should be great.

Tags round the wrong way

[UZZ30]

lol yeah i just notice that!

[NZcelica]

aaaaaaaaand your point??

[UZZ30]

about what? the soarer exhaust system or my error with the tags for the image?

[Mr.Phreak]

Meh, the biggest restriction are the headers anyway, the rest isn't too bad

[UZZ30]

yeah the headers are also pretty restrictive but i dont want to replace those straight away once i have this soarer at the end of the month. There tad expensive. any wya removing the 5 rear mufflers with and replacing with an xpipe ad 2 striaght throught mufflers is worth it, you get a good sound and you get more power, plus you have to do it first before you can do the headers

Headers are the best bang for buck tho, ive heard claims of 10kw at the wheels.

[Mr.Phreak]

Uhhh, why?

[Silent Knight]

Uhhh, why?

Yea what he said...

What has the mufflers got to do with the headers. After Market headers will still bolt on to your normall exhaust as they are normally made the same lenght with the same flanges.

Headers will give you a hell of allot more flow and increase in power than 2 straight through mufflers and an xpipe ever will...

[Mr.Phreak]

Headers will give you a noticable power gain, whereas the rest of the exhaust will only give you a better sound....Of course, doing both is best

[UZZ30]

ok yes, the headers are the best exhaust Mod.

But if you just replace the headers and leave the rest of the system how its is, you will have slightly better peformance but not by much as the rest of the exhaust is restricting the increased flow. And the other 5 mufflers stop any decent v8 exhaust note.. so thats quite poinless to do first, wouldnt you want to hear the engine first by removing the mufflers???

I would say its best to remove the 5 mufflers FIRST, so you have the exhaust note and rid the restrictive mufflers. then replace with what ive said before. That would cost around $450 for parts plus labour. Thats not bad as you can get around 18kw power gain.

The headers made by rush imports cost like $650 or so which is quite expensive, ill do that eventually but its not that neccesary right away, they give you an extra 10kw or so at the wheels which is great and shows how restrictive they really are the stock headers.

But You dont need to rush in and do everything to the exhaust unless your prepared to spend well over 1100 all at once. once i have this soarer ill be pretty happy with the set up ive said previously, i do agree the headers are the most restrictive part of the exhaust but all together the 5 mufflers are much worse.

lol doing all is best of corse!!

[Silent Knight]

So you say that by just doing the exhaust the way you described above and leaving the stock headers on you will be getting a gain of nearly 20KW @ the wheel?

If so please do it and then put your car on a dyno so I can laugh.

[UZZ30]

um no not at the wheels 18kw or less at the engine.

[UZZ30]

any way look at this, the rear mufflers and middle mufflers are the most restictive and cause the most pressure. The front section are the headers and you can see they create much less pressure so its best to do the mufflers first. Headers are last...

where did you get the figures to do that from ???
id like to se teh method of mesurement before i belived anything i found on the net

[NZcelica]

I still don't get the whole idea of this thread
You may want to look at getting a Soarer first? then tell us what you have done, rather than a thread dedicated to your exhaust system that you havent yet fitted to a car you havent got yet

[vvega]

bahahhahahahahhahahahaahahah

Um a very reliable source which i know is correct. The guy that tested it certainly knows what hes doing!!

[UZZ30]

hmm ok, this has been pretty pointless this thread, all i get is stupid replies from people that like to show their arrogance...

Any way ill prove all i have said is correct once i have my soarer at the end of the month, Thats right i will actually own a decent low kms soarer.

....yes thats true all im saying is you do the mufflers first before doing the headers! if you leave the quite and restrictive mufflers on and put higher flowing headers on theres not going to be that much difference as you sill have the restrictive mufflers stopping the headers increase flow! Plus the headers im talking about are twice the length of the stock ones.
