need some sound!!

2002auxr6 · 21-02-2006, 02:24 PM

hi every one i have a 02 au3 xr6 vct and im looking to sound it up a bit, i just has a 2 1/2 inch cat back installed but it doesn that a great deal different, if i installed a set of extracotrs would that make a hell of a differnce, if so how much would i be looking at

extractors will make the sound a bit deeper. You should be able to get a set of Pacemaker 4480 for around $500-600, or 4499 for around $450. prices are a guide only. JMM also does a race series/street fighter set of extractors for the VCT that go well - around the same price I think. Click on the Jim Mock Motorsport link in the sponsors ads at the top of the page, and browse for their prices (I think you have to add fitting).

If you just want noise, then remove the rear resonator (would be less than $100 to do this).

hmm im getting an exhaust from redcliff dyno in the near month, he said $990 for exhaust and 4480 pacmaker extractors, good deal but im just wondering how loud its gonna be, cus i want mine to grunt somthing cronic ay, like 140 db hahah

WILL IT SOME CRAP WITH THE REAR RESONATOR REMOVED

JC, my Forte is stock if i removed the rear resonator what affects would it have on the engine? As in pertol consumption? And what does it sound like?

Cheers

If i were to put extractors and a 2.5 inch exhaust how much diffrent would it sound compered to removing the rear resonator?

All i really want is sound at a cheap price!!!!

Cheers

Simon

i have the rear resonator removed on my AU1, 2 1/2 inch cat back, pace headers and a cat mod, sounds great but if u dont like groaning inside the car dont remove the back box, its louder inside the car but not so much outside and the extractors make it sound louder at lower revs but not so much at high revs, hope it helps with ur decision

Ok so if i just get a 2.5 inch exhaust from the cat back will that sound better then removing the rear resonator? What does the 2.5 inch exhaust from the cat back do anyway?

And how much will it cost for the 2.5 inch exhaust from the cat back not fitted?

Thanks Matt!

Cheers

my bro has a Lukey cat back system on his EF Fairmont i helped him install and cost him about $250 roughly but the lukey system doesn't actuall come with a rear resonator, i got mine done at a place in Geelong called Johnny Macks exhaust systems, he makes them himself, tis 2 1/5 inch, mandrel bent and cost me bout $300 fitted and it like most has a rear resonator, it only cost me like $50 for the piece of pipe to be fitted after i got the rear box cut off so for the sake of $50, put the whole system on and if u dont like it, get the rear one cut off.Bro got his exhaust through Autopro i believe, shop round, might be able to save a few dollars

So for the 2.5 from the cat back costed you $300 fitted?

FTG Auto Salvage quoted me roughly $250 for a TS50 2.5 from the cat back!

Is that any good? And would the TS50 one sound any good?

Cheers

maybe u didnt hear him right or something but im assuming ur car is a 6? i do believe the TS 50 is a V8 so the cat back will not fit ur car man?

eXi7w0unD · 21-02-2006, 10:26 PM

lol just make it fit force it on with ducktape and CLAG glue haha thatly hold, make it sound like a v10 aswell

Best bet is to take it to someone recomended ( by people you trust ) in your area ( you can check out their work before hand ) tell them what your after, then save the cash to have it done properly. No point paying out cash to have a droneing sound comming from your car, if you go through someone reputable they will make sure it stays legal ( decibel levels ) and they will usually mod it to keep you happy.

Good Luck

Cool, great idea! Will do some investigation!

lol ... if u want a louder car just drill small holes in your muffler ...lmao , or even better - take the muffler/mufflers off and burn a bit of the guts out of them with a brass welding torth fame

) - none of these mehods recomended , but they do work ! ..lol - dont know how they will effect your back pressures though ... very cheap easy mod for the adverage scumbag who doesn't want to spend any $$ ..lmao

XR6-VCT-2000 · 22-02-2006, 08:41 AM

sorry , that was Brass Welding Tortch Flame ..lol .. not torth fame !

Casper · 22-02-2006, 09:38 AM

VCT will sound different to the HP at high revs. They are not a deep burbly engine, they scream like a banshee actually. I've had mine accused of being turbo before due to the sound of it.. must be a VCT trait I guess as I'm not the only one. I wish.

XR6-VCT-2000 · 22-02-2006, 09:55 AM

Yeah i agree casper , the vct does scream like a banshee at high revs (sounds nice for a 6 , i like it

), only thing i can put it down to maybe is - it must have something to do with the vct keeping the firing of the cylinders better timed at higher revs / keeping the firing spot on according to the stroke rate ???????.

Darn smooth sounding/running engines no matter what the rev range, thats for sure

.

Casper · 22-02-2006, 09:58 AM

Its probably more to do with the VCT changing the cam making the exhaust slightly restricted, thus making a different sound. The cam movement has a "price to pay", in this case its in the exhaust.. also explains why the VCT is so touchy with what headers you use on it.

XR6-VCT-2000 · 22-02-2006, 09:58 AM

or vice versa should i say - the engine advancing the cam to suit the loss of distance of spark in the dizzy ( even with the vacume it still aint spot on in a normal engine ) .

AU's are coilpack.. no dizzy

:

XR6-VCT-2000 · 22-02-2006, 10:00 AM

ah yeah thats makes sence too , i can see what u mean how it would effect the timing of the opening and closing of the valves compared to pistons positions and firing time too .. hmmm

XR6-VCT-2000 · 22-02-2006, 10:03 AM

) sorry , i was thinking in old terms with dizzy ..lol , yeah i forgot these are coil pack , 3 in the au yeah ? ( 1 for each 2 cylinders / those 3 black packs yeah ?) ... im still getting used to all this new electronic cars lingo , im used to a big dirty old thumping v8 , bit of spark and fuel and off she goes ..

) ..lmao ..sorry

XR6-VCT-2000 · 22-02-2006, 10:07 AM

Casper ...with that above too what u said , makes a bit more sence now why when i have read about the vct having different results with different exhausts compared to the hp .. thanks , makes sence now ;) ..cheers

Love to explain it in detail but I cant remember the exact details now. Was explained to me once ages age. Basically, the VCT gets its exhaust vavle timing changed and this actually restricts the exhaust. Therefore, to get the best out of the engine,you need headers that use the exhausts own pulse to the maximum effect to pull the next pistons exhuast out (scavenging effect). If the headers pipes are to big the scavenine effect isnt as effective and the results on a VCT are pretty obvious.

Something like that anyhow.

Coil packs there are two from my memory and they ain't cheap I had to replace one in my AU1 XR6 VCT and it had only done 120.000

2002auxr6 · 22-02-2006, 10:28 AM

anyway what i was saying before will taking the rear resonator out make it sound sh it

XR6-VCT-2000 · 22-02-2006, 10:31 AM

yep i got ya ;) - gee that would be darn hard to come up with a perfect efficient exhaust system for ! - sounds like everything has to be spot on matched to each other .... i think i will do some serious research into this be4 i go blowing any $$ on mods ... thanks again .

oh as i said earlier - excuse my bit of stupidity too !

) ..lol - as u know allready alot of the 'old school' motors still work in the same principal and alot of the same rules still apply when looking for power/performance/results etc etc .. Its just these few new little bits of electronic gizmo's im learning about ... First time i looked at one of these newer engines i was like "WTF .. i aint toutchin this ! " - but after reading about them a bit i see the good old engine hasn't really changed much at all , just looks a bit different with a few things replaced with electronics now instead ..... thanks for all the help so far anyways - all u guys ;) , cheers .
