VE SV6 Exhaust

[lclynch]

Hi guys
I just got a set of Hurricane sports mufflers and quad tips put on my ute, though its still not loud enough.
The guy who did it told me "if you want it louder, come back and we will cut out the rezonator's. Im thinking of doing this but i was wondering, will this upset the back pressure in the exhaust ?

Do you guys have any ideas on making the exhaust louder?

Here is a link to it.

Like can i do something like catback, or now i have the new mufflers do i need to start again to have a catback system?

Any help and info would be great.

Thanks..

you don't want back pressure in a exhaust. it's a total myth. cutting out the resonators may make it drone at certain RPM. there is only one way to find out.

just a note about exhausts n muffs, the closer to the engine the mufflers, the barkier the note, the closer to the bum, the more soft and refined the note. and any baffle type mufflers with make that breathy chuffing noise when your up it compared to a nice bark from a straight thru pipe.

this is a Stock VX V6 with Lukey 2.5 sports cat back and no rear resi. i love the note!

Shit man it sounds, alright aye. The pops are mad.
But now I've gotten these new sport mufflers is there a way to go cat back? like can I join on to them?
I just want more noise and rumble.

my opinion, scrap your current system, if you want a nice bark but still fairly quiet on cruise revs, id put a straight through type muffler(2in/2out) in the center and then just have straight pipes. and if it ends up getting too loud like that then maybe a hotdog on each tip (it should be a twin type system all the way down yea?) based on previous exhaust building experience i think that should sound as clear and barky as its going to get without sounding like an excell with a fart can.

mmm i just spent 450 though thats the thing.. my mate got quoted 800 for xforce catback, naybe i should think about that..
i just dont want to waist my money. thats why i was hoping i can bolt something on to my new setup.

[klampy]

in that case then, a have a couple questions for you. is there a center muffler after the cat? and in the rear muffs, are they straight through units? (can u see thru it? most twin exit muffs are baffled. if you change them to a cannon/hotdog style it will change the note again.

baffles ALWAYS take the crisp edge off the engine note.

Just remember mate that is the 3.8 ecotec and they always sound better/deeper then the alloytec

yea, im keeping that in the back of my mind. the few VEs that have pipes on sound like fart cans...

yep, however theres a few with xforce 2.5 systems that dont sound too bad considering

[lclynch]

yeah i had a VS an it had no rear mufflers and only a small middle one. with the straight pipes.
sounded heaps loud.
i just spoke to them, and they told me they can just bolt on and run a catback setup.

[klampy]

being a VE/alloytec, im not experienced with the way it should sound, but in general, most engines sound better with a straight thru type exhaust. so if the cat back type system has that center muff/hotdog/resonator just after the cat, i would go that way with straight pipes under the bum. if its too loud like that then think about a couple small hotdogs or even a couple small straight thu muffs under the bum to take the edge off it without sounding like you filled it with cotton wool.

thats my opinion.

edit: i used to work at repco, and sold plenty of lukey systems to people who wanted a little more bark that just asked for a cannon. and 90% of ppl were pleased with the result.

[lclynch]

i went back and they took out the rezi's sounds better now and a decent amount louder. and i get no drone.
if you are looking to get work done Windsor Exhaust are awesome and cheap.
a few hundrend more and he will make it full cat back... ill do it in a few more weeks

[klampy]

you should post up a new vid so we can hear the difference also. and give it a good rev!! lol

[lclynch]

yeah will do

here it is now

[klampy]

yep nice. it has that sizzle to it now. id love to hear it under load.

but the imortant question, do YOU like it?

[Kieran263]

Much better
do YOU like it?
That's the important question.

[lclynch]

Yeah thanks guys.
I do like it now, I don't think I'll bother joing on a catback setup now. I dont know if it will make much of a difference.
Maybe some bigger cams to make it more lumpy lol.
