To all owners of VE SS or SSV wagons with modified exhausts

[loku16]

Hi Guys,
I have a VE SSV wagon and got a full 3" exhaust including OTR and extractors from VCM. The bloody thing drones at 2000 and can't seem to get rid of it. I know some places guarantee that their systems will not drone but I'm asking whether your wagon drones at 2000rpm and if not, what system you have. The boys at VCM put some sort of diffuser in the mufflers but it has helped only marginally and they say they have not had this issue in any other wagons. They said my large wheels 20" with 275s at rear might contribute but I can't see how.

I know that we don't like to criticise our own cars and the mods we have done but I would appreciate honest feedback on your exhaust system.

Thanks in advance.
Arj

Personally I think your problem might be the 3 inch. I have a full HM/Perry 2.5" exhaust including extractors and outlaw cats fitted by Walkinshaw and there is minimal drone. I am off Walkinshaw now as I have had a horrid experience recently. But the hardware is good.

My sedan drones a bit at 2000rpm but I've only got a 2.5" cat back at the moment, I'm getting headers and a VCM otr cai soon.

Brothers wagon has no drone with his 2.5" full kpm system, it's a manual too.
Is yours an auto? Most systems will drone a bit in the wagons with autos, not much you can do about it.

Wagons are very difficult. Kinda thinking the same as RUF. is the AFM off??
the only other thing that could fix it is change your diff gears to a 3.45 or 3.7..will get it out of the drone zone

AFM is off. Has had a full tune too.

I was thinking the same. Expensive option though! Wondering if I put some HM/Perry mufflers whether that would help!

Think this guy might be on the money? I know you can put 3" on v8 but majority have 2.5 the three is sometimes just to big an its sucking out to much causing the drone affect when cruising around that RPM, I could be wrong do you have a mate with the same car or that could help you out an swap exhaust for a week sort of thing?

VCM market their 3 inch as the quieter of the 2 (3 vs 2.5) in their range, for stock motors. They recommend against fitting a 2.5 inch to a wagon incase it drones.

I know you've been struggling with this issue for a while, Loku - I would have thought they'd have sorted it by now. All the best with it mate.
