VF SS V Exhaust - sedan

[crackpot77]

^^ nah AFM saves 35%, get it tuned along with the performance tweaks. Worth keeping if you neutralise the drone.

Do you have drone? From my understanding from talking to exhaust specialists it is wise to do a dod delete but if the drone doesn't bother you than that's fine. I'm not to concerned about the price of fuel for my ssv, I'm basically spending $100 a week on petrol if I drive around town all week but was spending $80 per week with my ve sv6, I own both. The sv6 is my mrs but love driving the sv6 to work as it's more agile, less heavy front so less wear on components and then just drive the ssv around on the weekend, side ways if possible

No I fix that.

A good specialist will know how to deal with this sort of problem rather than turning it off. Half a dozen popular cars going back to the MK1 Lotus Cortina had a tuned resonator or helmholtz chamber from the factory that eliminates this sort of problem. VW VR32 and a few others deal with it the same way, delete it and you have to fabricate a substitute, not modify the engine management to accommodate surgery.

Depends how, where and how much you drive really. I do country highways mostly with a load, between 2-3 tanks a week.

It was surprised how heavy the SV6 was! I think the weight difference is about the same as carrying a jack, spare and tools or a 'full sized' passenger (115kg).

Pirate, you do a lot of highway driving. So AFM is probably beneficial for you. My mate has a ssv redline wagon AFM barely kicks in as he isn't on the highway much.

^^ yes and my AFM is tuned to be on a lot more across all driving, no problem now that AFM noise is attenuated.

Hi guys, i recall there being some compatibility issues for the series 1 VE exhausts with the series 2 VE because I think the hangers were shorter? does anyone know if it's the same on the VF?

I have some quad exhausts from my series 1 VE and will be getting my VF next month so was looking to bolt these on.

Thanks!

Can you tune AFM up come on more?

Yes! Have mine tuned to operate across a wider range. I think the tuner takes into account many parameters that portray engine load like vehicle speed, rpm, gear, MAP, throttle position etc...

You make it sound so complicated..... Manifold Volume, RPM, Throttle. Some people are lucky and you can just set it to only run in drive and have it disable in sport or manual mode on some of the later cars, I think the series 2 you can set that. Then you can have the best of both worlds, v4 economy with the ability to put it in sport if it bugs you and have it just run v8 mode which is handy if ur going on a long trip

35%? Never heard anyone claim that. Under what conditions? Most people say they don't notice any difference.

Ok now we are getting to the point! Is like quoting max hp on a dyno, only real context is on the road:
On long flat high speed runs is as good as the latest Prius (definitely better when you factor in 300kw/630nm atw).

Typical 100/110k highway gradients (optimum at 115) still gets about 25%, and around town 0-80k - too much variance - really depends if you drive differently in order to make active more often otherwise it just works in the background saving 10% - 15%.
At $100 a tank, two or three times a week, makes me smile at the pump jockey every time.
