Sorry, I have been away for a few days. When I first drove the car after putting on the headers, I couldn't really notice much difference. When I took a log, you can see that there was really only a power increase above 6000 rpm, and that's why I didn't notice any real difference.

I then sent the log to Edward, who retuned the car and now you can see the results in v11c and it feels really good, it is a very worthwhile modification.

Just to clear this up, before the headers were added my car had 100 cpsi cats and the front section modified, the original middle section and hot dogs on the rear. It sounded okay with the original front section of the exhaust, but since the cats have been changed and now with the headers it sounds terrible. It's a real tinny sound, almost like an early 70's Fiat 1100 or 1300, if anyone can remember them.

So the middle and rear sections of the exhaust need to be changed so the car doesn't sound like a Fiat 1100. The bloke at the exhaust shop said if I do that he is certain there will be more power, but I don't expect much more. Anyway, I will find out when I get ahead with the $ a bit.

I have a question

How many owners take their 3.0 out to 7200rpm for a blast a few times a week?? Say 2-3 times

I do it several times a week, but a lot more often I would go to between 6000 and 7000.

Thats great to hear, I am sure you can adjust the tone to whatever you want, its just a matter of mufflers, the right size in the right position. On my car, its still 100% stock sound everywhere around and in the car, but like you say with the more open cats - they will sound pretty tinny

I would love to experience your power curve, that should feel significantly stronger than before

I think you have been sent a V11D to try, one would think that most of what has been found is the near sum of all the potential, but then again - you never know with the talent of Edward

[BJ]

Yes I have v11d now, but I haven't had a chance to do a log yet.

Requoted to save u the search

Thanks, I had no problem locating the graph as it was only on the previous page.

I was partly confused as the graph refers to "Raptor Headers"

I know the SC is also referred to as a "Raptor", so I thought the results were on H6+ SC...

BTY I am interested, but not right now due to $ considerations

I would need to also budget for a less restrictive middle exhaust setup as well as a proper tune to get the best benefit.

Raptor makes, Superchargers, supercharger kits, intercooler systems,headers and anything else it believes is something the free market wants.

Raptor headers are for both NA and SC engines, offering significant power gains

Yes, making it sound good won't be a big problem. I am very happy with the extractors, the extra power is really good, and very noticeable. Based on the original standard exhaust and no tune, which is 128kW atw, it is an increase of nearly 19%.

[BJ]

So, have any of you on here used the X-Force cat back system? Are the rear mufflers straight through, so if you dropped something in one end it would come straight out the other end? How does that system sound?

[SH30RB]

I've got the xforce system and it sounds great! Its a straight run through like you said

[BJ]

I've got the xforce system and it sounds great! Its a straight run through like you said

Thanks SH. That sounds like the go then, particularly as it's only $695.

Id go for the mild steel system from best mufflers in sydney, $330 and then what ever delivery is.
Arent tim's extractors made from mild steel?

[BJ]

Yes, they are mild steel. So do Best Mufflers have a cheap mild steel system? I will call them then and find out. I guess it's similar to the X-Force system but in MS.

[SH30RB]

Yeah, its the same xforce system just made in ms. Coated in a mat black paint for added protection

For anyone watching this thread, I dont want anyone to be under any illusions

The get a nice "little" gain with no losses you can simply bolt the headers on, you get 5-7kw and up to 25kw past 6800rpm

For those chasing the "BIG" gains, you need the headers $$$, full exhaust $$ and an XTR tune$$. Of course you can do it in stages, but thats how you got to the 19% gain region

I dont know if I would recommend making the cooler section of the exhaust in mild steel, at the back where all the condensate and juices collect on short runs - eats out the zorst.

Its ok to be mild for headers as they always operate at high temps even after a few seconds of running they are scorching hot, but that doesnt apply to the entire system, especially not in the cooler climates, the XFORCE stainless could be the better bet .......... or something else in stainless
