Hi, I want to install in my ISF JoeZ exhaust and Sikky Headers. My question is: if I install one of this two first i should start of exhaust or headers? Is it any diffrence? It have any influance on performance?
And second thing is... What about performance after install this parts? How about time 0-60, vmax etc.

Thanks

i say go do the headers first. exhaust is pretty easy to do. also to let u hear the headers without the exhaust and see if u prefer that or with the joe z exhaust.

And what about performance? Do You know something?

The headers will give you more performance gain for your money, but will not change the exhaust sound too much. The JoeZ exhaust will make the exhaust noticeably louder/better, and will bring you a performance gain, but not as much as the headers.

Sounds about right......

The headers alone go for $1,295 and will give you an approx gain of 25 rwhp

~ Average install labor is $500-$600

The exhaust system goes for $1,599 and will give you an approx gain of 20 rwhp..

(more material used to make an exhaust)

~ Average install labor is $100-$150

Combine the two bolt on systems and you are in a very impressive 40-45 rwhp approx. max gains..

These are just some ball park numbers based on various dyno tests using a Dynojet Dyno..

Forgive me if this has been discussed elsewhere (I did search). Joe - any differences for the intake/exhaust 2010 vs 2011 IS-F? The l-tunedparts website does not list 2011 as a choice. Thanks!

No there is not...

Both products work perfectly with the 2011 IS-F.

They just haven't updated their site to reflect 2011 (yet).
