As planned, went to PPE this morning and a pre header installation dyno and left my F off for the header install. Guys, the PPE header is gorgeous, the workmanship was outstanding I really can't say enough good things about what I saw. Maybe these picts will do the talking. IMHO, these are the ones worth waiting for. PPE is planning a Group Buy when the first batch is released. Mine will be on next week

Lou,

Mate those are gorgeous headers., Did they give you any idea on prices , or if they can buid a RHD set.?

There is def a market for these ISF parts over here in Australia. My Dealer just ordered 10 Icode intakes...and there all sold...and more being ordered.. so def a market here.

Will watch this thread in the up coming weeks,

Richie

Like i said in the CL thread, i love these collectors they look great (i also love the ones i already have installed from elite). Other wise these would be on the list.

as for the elite ones they are releasing there new version this week or next week, i know there is a second car at elite that is getting picked up next week from them and it has a completed set!

Everything is done and my car is back home. I can feel the extra bit of zip, and the sound in the cabin is a little, not much, but IMHO, better. Remember My exhaust system is now made up of the PPE headers, Magnaflow high flow cats, and a fabricated dual system utilizing stock mufflers and glasspack resonators. A dyno taken before is attached.

A dyno run with the same type of dyno (Dynojet) is attached. That F had sikky headers, not cats and a JoeZ exhaust. Peak results are similar, except the PPE seems to come on a bit sooner.

It's not apples to apples though. The PPE's appear to come on sooner, but there are other factors that could be at play resulting in the difference such as the stock mufflers being in place on your setup. Unless you have the same exact exhaust setup as me you can't conclude that the PPE's are what make the difference.

So there are variables at play here such as different exhaust setups, different dyno facility, etc that all could play in the equation. Unless you bolt on a JoeZ exhaust and compare it back to back with your current setup, this whole header comparison is worthless.

I respectfully disagree. Both cars were run on the same brand of dyno, the outdoor temperatures were the same, however, the exhaust systems were in fact different. You are using the low restriction JoeZ, that gains 20 HP over the stock exhaust system. The Sikky's gained another 27. My exhaust showed a baseline of 354HP before the headers, your's with the JoeZ showed 352, pretty close. IMHO, the results are pretty comparable, but it does appear the PPEs come on a bit sooner. Both are well designed and both make power. The choice is yours. I am attaching another graph of yours that shows what I am saying. Again, IMO, you did a great job outlining the true benefits of a decent hiflow exhaust on the F, versus the inflated numbers JE was showing.

And, I only added your info because someone asked to see it. Again, IMHO, competition in the marketplace is a good thing!

^^^^I'd expect you would get the same results. If you didn't run cats, it would probably be better. I'm very happy and satisfied with the results I gained with the PPE Headers and the Hiflow cats:D

Looks like final release within 2 weeks. Retail price $1399 complete with JetHot Ceramic Coating. A group buy will be available upon release with the discount corresponding to the number of folks who sign up for the first build. IMHO, this is all great news.
