    Guys, my wife and I have just bought a VY SV8. While it has heaps of grunt when compated to the old VR V8 we had, it sounds like a sewing machine. What sort of exhaust do you guys have on your Gen3s? I'm after a set of pacemakers and a twin 2.5 but I'm undecided on the mufflers?
    thanks, pest

    I have a VYSS with cat back only Xforce system twin 2.5" no resinator and it sounds sweet as good as my old VPSS pacey's are the best extractors for the ls1 but you wont feel much of a performance gain unless you get an edit done.

    VU ute man, I've heard about that sort of exhaust before as well. Minus the pacies, how much did it set you back for the exhaust, cat back? And also, how hard is it to find magnaflows and do you have a sound file of your beast? Do you get any drone too? Sorry for all the questions, pest...

    I had a Manta system put on my gen3 twin 2 1/2 inch from cats back running through 2 hotdogs into a resinator, nice sound with no droning.

    I have a mild dual Sureflow 2.5"

    goes well. Needs more hi-flow cats and headers though

    the note in your exhaust dep on a few things
    a) mufflers used
    b) cats
    c)bends circumference
    d)induction mods will help with that roar(ie mcai/otr)

    hey guys,

    i have a vx ss (auto) and i have just had a full di fillipo system fitted. Extractors and 2 1/2 inch tiwn cat back. I had the cats opened up as well. It sounds awesome but doesnt have the drone normallly associated with an auto. I shopped around heaps and went to a few specialty performance places that mainly do ls1's and they all said save the money and go with the di fillipo system. i am glad i did as it sounds and goes fantastic!

    Cheers

    I got a pretty good price. I shopped around a bit and i managed to get it for $1800. but that was through a friend of a friend. Normal cost would be about $2500. Well worth it though. I went for the MCAI as well. Although with those 2 mods and a BMC air filter i seem to be getting worse fuel economy than before. initially i thought it might have been coz i was a bit heavier with my right foot but have backed off a bit and it is still worse

    I have a full VY R8 HSV exhaust incl headers...and if you remove the rear muffler you will get an awsome V8 sound ;)

    lots of 2nd hand HSV exhausts out there cheap...like 4/500 for a full Stainles incl headers.
