Fine product, been on car for 2 weeks- but with corsa's a bit loud for me- as loud as WFM exhaust- and they are tunable but not with the WFM tune- GREAT PRODUCT AND EXELLENT SERVICE/SUPPORT from Nick at ARH- so if anyone very wants a good deal on headers and is prepared to dyno tune for them PM me.......

Will now go back to stock with corsa, modded airbox/CAI, and 9.5 ring/pulley with WFM pulley tune- also have front heat exchanger

Anyone else beside Cadv who had some problems running just pulley/intake without problems? Insights?

Thx

Sorry to hear of your decision.

The V2 is still a new product, so I understand there are kinks to be worked out in terms of the tunes and equipment available. I was thinking about doing some of these mods but will wait until they are proven quantities (e.g. successful on multiple daily driver cars).

I'm putting the AR headers on right now at the Vette Doctors.
I'm actually having them re-tune the car after Lingenfelter.
Lingenfelter changed 5 parameters, they hardly did anything.

Tuan I think i will send the headers to Jesse first although i am still deciding- if I change my mind I will certainly pm you so don't buy new yet!

SS-Problem is not the header but the need to dyno tune them- i do not desire to just turn off the rear o2 sensors to make them work- Jesse is willing to rework sensor positioning to work with HIS tune without shutting off sensors or dyno tuning which would leave a irreversible ECU footprint.

Anonfrank- agreed- we are all essentially guinea pigs right now- better not to mod and "cross your fingers". I still think mods that can be removed are very different then ones that leave a permanent computer footprint.

kencave,

what wrong with the position on the rear 02 sensors?
if there positioned above the 3 oclock and 9 oclock that should be sufficient.

SS- from what Jesse has explained to me it is the depth of the sensor into the header that is the primary problem- I said repositioning but should hahe clarified that

Nick spoke to Jesse and even sent bungs to my installer here in VA. Nick has been very responsive to input from Jesse, my installer and my concerns. Most people just turn off the rear o2s in this situation- tune them out. Trying to find a different solution here.
Here you though SS- we will see how this pans out.

....and we DEFINITELY, heartily applaud your effort and Jesse's (who's spent more time than anyone outside of GM Engineering with this car). :highfive: Your curiousity, work, and annoyance with the process of getting it right without CELs :) will make many people (e.g. me :) )happier down the line.

Had the same problem on S2000 headers and test pipe. Did you try adding a washer or 2? This solved it for us. It moved the o2 sensor a little further away. if htat doesnt work then a longer nipple will have to be welded on.

It's a quick, easy and cheap thing to try. Just clear down the code each time you add a washer. and repeat..

Just a thought

Much appreciated, but please direct your thanks to my wife. Without her patience here I would be checking the fine print in my life insurance policy!

WHY WOULD YOU REMOVE THE PART THAT MAKE'S POWER AND LEAVE THE PART THAT DOESN'T.I PICKED UP 50+ RWHP WITH HEADER'S AND TUNE AND MY CAR SOUND'S GREAT WITH THE STOCK MUFFLER'S.THE STOCK MUFFLER'S DIDN'T LOSE ANY POWER WHEN WE LEFT THEM OFF ON THE DYNO. MY CAR WITH HEADER'S, PULLEY, CAI AND TUNE JUST MADE 620 RWHP AT THE VETTE DOCTOR'S IM NOT TAKING MY HEADER'S OFF.:patriot:

Ken, I've spoken with your tuner regarding what needs to be done as per my discussion with Jesse. I value Jesse's opinion and made all the necessary adjustments for all present/future systems shipped. I think it's a huge step backwards removing your system. The ARH system was designed to deliver outstanding performance while providing many years of trouble free use. Resolving this issue is top priority.
