I thought I'd share a clip Sikky posted of my car on the dyno after having their newly designed headers installed. BIG power increase. Feels like I have a whole new car, I could not be happier.

 

Seems typical of all other fbo ISF gains?

 

wow that's loud as hell. What's new about these headers?

 

I wouldn't focus too much on the peak number, it's the delta that seems impressive to me with +45hp. But two things to consider if you're focused on the peak number: its been hot as hell here in the mid atlantic, so I'm sure intake temps were less than ideal. Also, I have a bit of an issue with my intake - damaged airbox from over tightened clamp. Think we got it patched up best we could, but conditions were the same before and after headers, so the delta is what is significant to me.

 

Mainly the fact that they have 1 7/8" primaries, and stainless.

 

Seems typical to me too.

Edit: Never mind. Saw the response.

 

Looks very nice but expensive for non EL. $2195

I'm not sure I understand why there's such a different in price, I guess the bigger primaries? Sounds mean!

 

Anyone know how big the primaries are on the PPE headers?

 

The $2195 includes install and dyno. Unfortunately that's your only option right now. Sikky wants to make sure there ar NO issues before selling retail.

 

It is my understanding that prior to these, all isf headers are 1 3/4.

 

Pretty good price considering it includes the install!

 

I'm curious if 1 7/8" tubing (primaries) equates to bigger gains throughout the rev range then why wasn't this diameter used before with Sikky & PPE when they released their headers 5-6 years ago instead of the 1 3/4" currently used??? Why is it just being implemented now?

Not saying these don't give the gains shown but am just curious as to what some other opinions are about this.......

 

Those curves look amazing. Really looks like it evened everything out.

 

Fbo options seem maxed out. Nothing can get us more than a few HP besides boost.

 

Do you still need to relocate the dipstick ?
