Exhaust Help Plz

[John-]

Hey all, just bought my BA xr6t 2 dayz ago and let me say I looooove it, Now. lol. im looking into getting an exhaust done, was just wondering whats the best setup for the best flow? and the best sound? im after flow and performance, and im wanting an exhaust that in say 6 months it wil get me to 350rwkw? if not more. maybe less but that's in the future and I dont want to upgrade the exhaust again, so guys, I would love a little help in to what im really after? what do I need in order to be able to have 350rwkw some day, and for the time bein to make a nice deep chunky sound :D

and yes ive searched but I diddnt find anything and im on dial up, loads a page in 5mins, very painful.

Thanx in advance

John.

Simply put, no exhaust will do both.

Any exhaust that's gonna flow 350rwkw is going to make the engine overboost without a tune. In order to combat this, you also need a flash tuner & custom tune. It's a little ointless having a tune with exhaust only though so add in injectors, fuel pump, cooler etc... Get the idea? Haha

Your best bet is to take out your centre muffler & replace it with straight pipes/hotdogs which will give a throaty sound, then spend the exhaust money on a tune, injectors & fuel pump instead to give you the performance You can then upgrade cooler & exhaust in the next wave of mods & have it retuned to suit which will give you 330rwkw+.

Sorry to put a dampener on things but hope this helps.

... my first mod was a exhuast.. got the xforce stainless system from turbo bak.. that lasted about an hour before I took it down to the tuners and got injectors put in and fuel pump and tune.. as 03xr6t said.. its pointless gettin just an exhuast.. if u lookin for a bit of sound for mean time.. get a catbak exhuast. but leave the stock cat.. so when u have saved up a bit u can get a new cat, remove the 2nd muffler, injectors, pump, tune, cooler, plenum, etc Edited 10/11/08 08:23 PM by typhoon_freak

rito rito, thanx guyz :D:D, so I got a quote this morning a 3inch pipe from cat back $900, and the guy saidit will be very loud border line rego loud, LOL .

So my best bet is to go with something like this, add a bit of sound, then down the track few monthz time go and buy, injectors, valve springs, flash tuner, get a custom tune, then get a new cat, with a 3inch dump to cat?

soundz good or ey?

A 3" single pipe is basically the same effective size as the stock system - and definately not worth $900 for a cat back either!!!

The stock system is a dual 2.25" system from the cat back, most people upgrade to either 3.5" or Dual 2.5". Pretty common to see these systems go for $500-600 in mild steel (stainless isn't a nessecity)

Where abouts are you located, we may be able to point you in the right direction...

im in canberra, my ultimate dream was to have 2 , 2,5inch pipes on either side of the rear of the car (4 pipes all up) that's my dream, lol he said to do that like $1800. so I was like ehh.

If you speak to someone like Gen-Tech, they could put a package together for you. THat way you can just save up and get it all done at once

Gentech are a site sponsor so give them a call & tell them your a member of the forum. They'll point you in the right direction for sound, performance & budget

so... how about for the mean time to get some sound out of my baby I get a 3.5inch from catback and new muffeler for around $400 or so, then I buy injectors600cc or so? ($400), capa flash tuner ($500), nizpro value springs ($300).

so $400 cat back exhaust sound :D

then spend $1200 on the capa,springs,injectors and then go get a custom tune $600 or so. then wat power should I be pumping out??? any rough ideas??

then in 6 months time pay to have my gearbox strengthend, get a walbro fuel pump, and finish of the exhaust 3.5inch from dump pipe to cat, a new high flow cat, then retune? what power are we thinking after all of this???

any comments would be appreciated...

Cheers John.

Your going to have to factor in installation of the valve springs ($500-$800) and injectors ($100-$200). Depending on where you go. I would get a fuel pump installed at the same time you get this work done. The walbro cost about $150-$200 plus about $100 to install but is well worth it even for insurance sake(Just dont take note of my sig as I havent done it yet lol)

I have read and been told the standard exhaust with upgraded cat is good for 330-350rwkws. IMO I would just upgrade the cat and remove the centre muffler. It still has a loud sound. Any louder for me is too annoying.

I cant see what type of gearbox you have but if its an 4speed auto, I would be very wary of going over 300rwkws for longevigty and anything near 350rwkw you will have issues with rods requiring a engine rebuild in a BA. To get anywhere near the 350 in a BA you will a big cooler and plenum which is about $3k, which you havent mentioned at all what cooler you will get

Me personally 296rwkw no valve springs done, is fine for daily driven street car. See my sig for mods..
