    I was looking to upgrade from my stock exhaust because it's almost silent

    How much would it cost to get good sounding and what type/size?

    Asking because I know alloytecs are known for sounding complete ass

    Thanks

    Do yourself a favour, don't do it. Worst waste of money I ever got talked into by an exhaust shop guy.
    One day, when I can afford it, I want to have a complete new original exhaust system fitted.

    It's a custom made twin 2.1/4" stainless steel system with a 2 in 2 out muffler between the cabin and the diff and another 2 in 2 out muffler at the tail.
    The free-er flowing cats were the 1st mistake that resulted in a recommendation to replace the rest of the exhaust system to solve the horrible noise the new cats were causing. Then it was recommended to fit two 18" hot dog mufflers between the cats and the 1st muffler to help reduce the volume and the headache inducing drone created by the new exhaust system. Suffice to say the hotdogs had limited success.

    If you want a nice sounding exhaust note from the V6 you'll need to add an extra two cylinders.

    I think I have spent close to 3k all up on this exhaust system. In hindsight it would have been cheaper to spend the $700 on the one genuine replacement cat that was originally required, instead of opting for the pair of aftermarket free-er flowing cats.

    Depends on you most people go for red back sports, Rhino is top of the line but big money, I my self have a rebel sports from cat to tip with twin outs, sounds good and cheaper the red back but yes the sound can be overwhelming at times, you can just change the resonator back half and get a nice sound without center for cheaper, its up to you in the end, you will never get the sound of the real thing.

    Word of advice, don’t do it , not worth the money, and save yourself the eventual headache

    I haven't yet heard a nice sounding aftermarket exhaust system on a Holden V6. The good old Red 6 sounds better than the V6.
    Having an auto behind the V6 only makes the mind numbing drone worse.

    Well I did visit the shop here and the guy recommended a 2 1/2 inch hotdog centre muffler rear..

    He said that that's the highest you can't go because at 3" it starts to drone
    I don't necessarily want it to be loud, just want there to be at least soemthing ya know?

    I had a resinator delete on my V6 and it sounded like arse. It was droney on the highway and raspy when you put the pedal down. I since fitted a 2.5 cat back Redback with resinator and its quiet but that's what you get with a V6.
    As for Rhino being top quality, not sure about that. Blokes i have heard that fitted them said the pipes didn't line up properly with the original mounting points and cat.
    If you want some more noise fit a CAI and some Pacemakers. That will help a tad and won't sound terrible.

    Is there at least a bit of okay sound with the 2.5?

    Sounds almost stock on a Buick, even with Pacies, CAI and rockers and that's the best it will get. You could get a 2.5 with dog and muff and see how it sounds but get one where they can fit a resinator if it needs it as chances are you will. I get smidge of induction noise and not much more but its better than rasp.

    I got rhino exhaust on vp v6 ute...it's cheap for a reason.

    Hit just about everything...had it on/off several times to belt in wherever it touched.

    Now using it for v8 not only does it need more clearancing it's almost as quiet as a stock car

    Then change to 1st gear around the street to hear it pop lol, yes true but the straight 6 you can change over the extractor as well to get better sound its a bit hard to with having all the anti pollution gear on new cars, mine not a drone sound its a reverb sound and at times makes my ears go crazy. Everyone to themselves, rebel sound better than the redback I use to have.

    Just have a straight out pipe, lol. I just compared prices and I assumed rhino were good as they cost more than redback, I like the rebel I have its sounds ok.

    Any aftermarket exhaust system fitted to a Commodore with Alloytech/SIDI engines will make the Baby Jesus' ears bleed...

    Glad I saw this thread as I was thinking about getting something but might not now. I like the way these motors sound at high rpm though, might get a pod just so I can hear a slight growl.
