Jeff, those headers sound mean!!!!!!!!!!!

It sounds badass w/o the muffler !! What about the same setup with the TRD muffler on ?

Does it sounds as it performs ?? That's the question...
I know can't be as a turbo or SC boost...just want to know the WHP added

^^ as previously mentioned, we're awaiting yet another mod to the Y-pipe before getting it re-dyno'd to see if we can get the power curve we're looking for. Right now the bottom end is weak because too much airflow.

Will update as soon as I get the new Y and dyno again.

Thank you very much Jeff for the update !!

hopfully we get this thing going b4 spring time many future plans ahead and this is #1 of them. thanks jeff for everything your doing for us gen2's

Ugh! Searching 20 pages to find the video of Jeff's car on the road (not with the exhaust disconnected!)

Jeff:

I'm still searching for a Gen2 ragtop. This is taking longer than I thought. (I guess I'm too picky) Anyway, you can count on me to join in as soon as I land another 'Lara.

I'd like to experiment with running two balanced smaller diameter pipes in a true dual exhaust with hopes that bottom end will come back yet still get the gains of the headers. The system would be very similar to a design we used for the first version of the Pontiac GTO where duals came out on one side. It sounded very wicked.

guys is the group buy for JP header still going?

Like to see, it still alive...even more then ever !

Phreak - how/where would you run the pipes anyway? Duals won't fit without mods to the undercarriage/trunk area/bumper.

Waiting for a new Y-pipe for next testing. JPP hasn't notified me yet.

The pipes would run side by side down the current tunnel and enter a dual in / dual out muffler or dual 4" rounds. This works fine for all but the SE Sport with the body kit. Unless they wanted to do some cutting.

We'll see, let's not put the cart in front of the horse.

Screw that! Fess up boy!! That would eliminate the Y-pipe and everything back!

You didn't think I'd put that in writing did you? LOL

Okay - you're either considering going with really tiny pipes or you're pulling our legs.I checked with JP today and they said it will be worse than what I currently have. Our 3.3s can't handle that much flow - total loss of low-end torque/HP.

Okay - here's the latest update...

For those of you who want Dyno chart results, I think you're going to be SOL on this one. Dyno tuning actually made the car perform WORSE as the factory ECU is confused by the amount of airflow the CP-e is letting into the engine... which is why your car won't run without the MAF unitl they ship with it that overrides this phenomenon.

Split-Second has replaced the CP-e MAF with their own that not only deals with that, but also the greater airflow from the headers/Y-pipe.

We originally thought the loss of low-end torque was caused by the higher-flow of the new system but it was indeed the need for actual street tuning to override what the dyno-tuning settings were spitting out.

So I'm sorry I don't have numbers for you - just whiplash from the new tune adjustment and balder tires from getting a 1-2 gear burnout consistently from stand-still!!

I even got some tire chirp jumping on it in 2nd and it's really hard to break these tires loose at all on dry pavement!

So I guess for those who need real numbers, I better plan a trip out ot the track and record some 1/4 mile times for you. Other than that - I think this egg is cooked and the system should be close to ready for prime time!

I'll update with more details/info soon... we'll probably close this thread and start a new one once the package deal is set-up with JPP & Split Second.

Cool to hear some news !

So bottom line...

The CP-e cannot be properly tuned with the JPP setup isn't it ?
Will you compare your quarter mile runs with Mike's (down2thec) one ? I think gen 2 ragtop can do 15.8-16 stock
