mmmm.
Intakes, full exhaust, ECU programming, clutch & flywheel, LSD, light weight wheels, and spray if you really want power (just remember it's bad in the long run). I'm not going to recommend what brand bolt-ons you should get, since every combination of bolt-on's acts differently. Just go with whatever pleases you, or do your research and see what combinations give you the most power. Same goes for tuning - If you have a good tuner, of course your car is going to make more power then a shitty tuner. bottom lime - RESEARCH! kthxbai

This is my take on them. When i had them installed and on the butt dyno I really was confident in getting around 15whp and torque from it. However I only got 6 and 7 or something like that. But the thing about the headers compared to other bolt on mods is that it gains power everywhere in the powerband, not only the top end, which makes it feel like a completely different animal. The response from the car was so greatly increased I loved it. I would say the peak numbers wouldn't make it worth it but because of gains of 10whp and torque elsewhere in the powerband make it very worth it. And if you think about it, thats better gains than what a cat-back exhaust makes for around 1000 installed. ANd i took a look at a dyno I had which compared my mods at 3 stages, and even though i was so close to full bolt ons, my power was stock up to around 5000RPM and then all my gains were after 5000. Due to this aspect of more usuable power and top end power(best of both worlds) I find them worth every penny, that is after they get this new header distributed. Dropping my car off at STillen tomarrow so they should be avalaible for distribution not this monday but the next. Hope this helps
Just out of curiosity AH... How much was the total tab for all your engine mods including labor (don't include all the dyno runs you had done)?
I'm wondering what your cost / HP was on your build.

Fast INtentions Intimidator-1200
Fast Intentions Test PIpes-450
Injen Intake- 680
Technosquare- 300 (beta tester so got the first reflash for free, this 300 was for my second round of mods)
Stillen Headers- 1200 but I'm probabaly going to get compensated for around 3-500 bucks with a free gift so lets just say 900.
Pulley(worthless)- 300
I would have to say that this hasn't been an easy road as there have been many ups and down and problems for me but here is the end result i came up with without dynos.
So $3880 installed. This is how much it would cost if I did it right the first time and it's a pretty good ratio if u ask me especailly since it includes labor. Definelty would recommend that you don't get the UR Crank PUlley and thats about it. Not too bad for an NA setup and right under 4k installed. And of course you could save a lot of money if u did the labor yourself.

did you do it yourself ?
Since when did Ultimate Racing make HFCs for the HR motors?
Yep. They just finished correcting the problem yesturday as a matter a fact. Just finished the final testing of thier 3rd design on my car and my car is ready for pick up and production has already begun. They even stopped selling thier Version 2 heaeder because of the problem it evoked. So in theory you could call on Friday and order yourself a set. I haven't had the chance to test it out yet though. I'm just taking their word on it that they fixed it. I was told they even pushed the car to make sure under all condition it was good with lots of clearance and am todl it has been solved. I'll know for sure and report back when I pick up my car on Saturday.
