Looks good James. Too bad the strips are closed for the year. I'd be interested to see if you can still cut an 11.9. We need to go asap once the gates open since I may have some new goodies on my F.
Thanks man. I have no reason to believe my quarter mile times would change any though considering the power is the same. When I cut the 11.9 it was my one and only run for the day and I know I could have cut a better time with the temps cooling as it progressed into the evening. If I decide to go again in March when the tracks open I'll shoot you a message. My drag radials are on their last leg and I'll be lucky to get more than 2 more days out of them.Looks good James.

Thanks! The secondary O2's are doing nothing since the headers came with an O2 simulator that is wired into the ECU. Those extensions are there only for easier fitments of the O2 sensors. I have about 5000 miles on the car with the headers and to date no CEL.Nice work, so did the O2 extension prove to be effective and still necessary with the new Cats or did you just leave it on there?
Good to hear the headers are giving no problems. What do you estimate your 0-60 and 1/4 mile times are?10,000 plus miles and no cel for me.
Pending his upcoming mods his times would be the same as mine. We both have the same mods and dyno'd nearly identical on the same dyno. So sub 4 second 0-60 and high 11's are doable.Good to hear the headers are giving no problems. What do you estimate your 0-60 and 1/4 mile times are?
Engine under load in the 1500-2000rpm range. It's funny actually because according to my decibel meter the db's have not changed, but the frequencies that cause "drone" have all but been eliminated.Around what RPM were you getting drone before the cats were installed?
Was the drone that bad before cats though? I'm getting this exact setup but don't want it to drive me nuts. lol.Engine under load in the 1500-2000rpm range.

Drone wasn't the primary reason for me adding the high flow cats. I needed to pass my state inspection yearly which requires a visual check to see if cats are in place, the wife was complaining about exhaust smell in the garage and I had some rattles that I couldn't isolate. I would put it this way. If you drive around in manual mode most of the time the "drone" will not bother you because most likely the rpms would be kept above the drone range. If you like to drive around comfortably say with family members and the car is kept in standard auto, you will not be able to enjoy conversation with other people in the car.Was the drone that bad before cats though?

What size slicks are you running and on what size rim? i have an extra set of factory wheels and id love to be able to fit a set of slicks on. Sorry i quoted the wrong post...Thanks!
