According to HM, the 116SS will fit TL-TW Magnas.

But will it fit a 2005 GTVi KW Verada?

Thanks in advance,

Maurice

as long as yours is AWD, yes it will fit.

AFAIK, there is no mechanical difference between Verada and Magna. In my mind, the biggest difference is the deeper bumpers at each end :).

Yes they will fit a KW AWD Verada. And yes in advance to them making a subtle but quite noticeable difference. You should find on throttle response & midrange improved as supplied Y-Pipe flows so much better than restrictive stock unit. Best first performance upgrade for AWD.

I've got these fitted to My AWD also.

These will fit. The only differences were between the TJ and the TL FWD models as the exhaust was different in length. In the AWD the front section and location of the car is the same

What sort of $$ are you being quoted

Yes it's AWD. And thanks for the replies.

$580 on ebay including delivery. Now that everyone knows I'll probably lose it.

Well for that price if you dont hit buy now immediately you deserve to lose them. The RRP of these is $835 plus shipping, given you are in WA the headers are really costing you $540 which is less than cost.

FWIW, I've just fitted a set to my 2005 TW VR-X AWD. Did a before/after dyno comparison, which I've posted here: http://www.aussiemagna.com/forums/showthread.php?t=71053&p=1596077&viewfull=1#post1596077. Should give you a good idea of what effect they'll have on your GTVi's performance.

Thanks for posting this macropod. The graph is interesting for the clear improvement after just the HMs. It is encouraging for me as I plan to fit a set soon.

On a side note, regarding the dyno test method, I'd find it more useful if the horizontal axis was a linear rpm scale rather than linear speed. I suppose that's just how some places do it. I would also have been interested in a measurement below 2000rpm. The improvement at 2270rpm is quite clear however, especially the torque.

Cheers.

You're welcome. FWIW, if you also add a freer-flowing sports muffler, your % increases in torque and power should be larger throughout the range. That's because you're working from a lower baseline. I'm hoping to get the raw data, so I might be able to post a set of charts with an RPM-based scale.

Macropod, how much of a difference in power and noise was there after the headers?
Do you know of any other places in Canberra which have AWD dynos out of curiosity?

The difference in power is as indicated in the dyno chart. No appreciable change in sound. I don't know who else has AWD dynos in the ACT. I only knew of the one at Ultimate Tunes because that's where I normally take my cars for servicing.

I meant, how much of a power difference did you feel rather than the outright numbers?

I don't drive like that ... the car does seem to hold higher gears going uphill than before, though, which would be an indication of needing less throttle for the same conditions. Useful for towing. Besides, I doubt anyone would actually 'feel' what is in reality only a 7% increase in power and a 9.6% increase in torque - most would imagine far more than they feel!

FWIW, you can get similar performance improvements just by changing tyres to something that has less rolling resistance and is therefore more fuel efficient - see: http://www.yokohama.com.au/Tyres/BluEarth-AE01.aspx Of course, you can also combine the headers with fuel-efficient tyres and multiply the benefits.

On a side note, regarding the dyno test method, I'd find it more useful if the horizontal axis was a linear rpm scale rather than linear speed.
See updated Dyno posting for RPM-based charts.

Thanks macropod!
I need to clarify the situation with my insurance company on modified exhausts before going ahead with the HMs.

, I doubt anyone would actually 'feel' what is in reality only a 7% increase in power and a 9.6% increase in torque - most would imagine far more than they feel!.
I'm surprised by that, i would have thought 7% power increase would be noticeable in terms of acceleration time?

I'm not denying that for a moment; indeed I'm sure there would be a measurable improvement in acceleration. Like the dyno charts, that's something one can measure objectively, but Spetz was asking for how it 'feels'; an entirely subjective evaluation.

All too often I've read posts etc. from people claiming they can 'feel' the improvement product X (e.g. a straight-through muffler, aftermarket pod-style air filter, or 95/98 octane petrol in a Magna) has made to their car's performance when all it's really done is to make it louder & less powerful (muffler, air filter) and/or more expensive to run (petrol). To work, any set of mods needs to be carefully thought out. Too many of the boy-racer crowd think any after-market air-filter or muffler will make their cars/motorcycles more powerful without ever giving any thought as to what effect a reduction in back pressure or messing around with intake resonances & air flow will have. That's why I'm not really interested in subjective assessments; in any event, as I replied to Spetz, I don't drive hard enough to 'feel' the difference.
