i have a vx s pac and it has those stock cast headers on it and 2 and a quarter inch exhaust (stock) and i have cut the rear resonator off. it makes my car sound better and go a little bit better, is there much point putting extractors and 2.5 inch exhaust on it or do you think i should just get a cat back exhaust? i plan on gettin 1.98 ratio roller rockers and 69mm throttle body later on. thanks.
i would reccomend the extractors and 2.5 inch exhaust.. with the resonator on it sounds heaps good and without it, it sounds sshmick
if your after a sweet note and not sure which one to pick i could email you a voice recording or something??
Ecotec with a 2.5 catback and no resi sounds like a loud fart in a tin can.
When I still had my VX I put a 2.5 Redback on with the resi removed, about 3 weeks later I had them weld a fairly long hotdog in as it sounded so terrible.
Just to give you an idea, I had HM tuned headers, 2.5 catback with a 16inch (I think) hotdog and is sounded like this:
@25sec odd is probably the big you are interested in.
When I had the resi out, it sounded much more tinny.
Plus from the legal side, removing a muffler is illegal so that's something esle to consider.
Hi there i'm looking into buying a exhaust
When you said you had no resi fitted????Just a straight through exhaust?
Is that a muffler???
I am looking at buying one of these....Has anyone heard these??
Are they loud??

I think the Lukey is about the best sounding system for the 6.
Too many farty ones out there.
Kev
Yeah, a resi is the rear muffler on the exhaust basically. The small ones are called hotdogs because they look like a hotdog (sorta).
Straight through and removing the resi are 2 different things.
Straight through is talking about the type of mufflers used, removing the resi is just having straight pipes on the rear.
As I said, doesn't sound even close to good with a rear muffler delete.
Mate, it's all about personal preference... the subject of if an exhaust sounds good is very subjective.
In the case of the ecotec engines, I personally think that having the rear muffler removed makes it sound like a curry fart on a sunday morning right before a AGB.
Others will say its awesome. Best bet, is to put on youtube and see what sounds good to you on there.
I personally liked my exhaust sound on my old car while alot of people thought it sounded crpa and ricey.
as long as you have extractors it should sound good.. but yeah as the other fella said.. its all personal prefrence
