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.

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).

Best Regards,
