No need........they showed up today and everything looks great. I look forward to installing them this winter. Thanks!
Anyone used these on a na2 yet???
I don't think that NA1 headers work on NA2 engines.
I've also heard that unless you spend $$$$$$$$$$$ you won't see much if any gain on NA2 since they come with very good headers anyway.

ChongLee just purchased a set of NA2 headers.
I recently purchased Topspeed Headers from MR2Liter. I wanted to post up a dyno graph of my results. I will post up the before and after soon. I do have the dyno graph of the Topspeed header and the Prospeed Rom tune.
DETAILS
Dyno: Dynojet
The car has about 62,XXX miles on it
Mods- Stock airbox with comptech filter, Taitec GTLW exhaust, Top Speed Headers, Prospeed Stage 2 Rom Chip.
Note: We forgot to delete the older text that says "prospeed chip version 2" and "Airfilter with 3.5 velocity stack" We did some extra tuning with it and made the same hp so we kept the existing OEM airbox.
RESULTS
Blue line indicates run with only comptech filter, taitec GTLW exhaust, and Top Speed Headers.
Purple line indicated run with comptech filter, taitec GTLW exhaust, Top Speed Headers, and Prospeed Rom Stage 2
-Peak 270 HP with 204ft lbs of torque
-As you can see we picked up around 8 hp to 14 hp Throughout the powerband. 11hp at 7000rpm.
-The NSX saw excellent gains in torque gain from 8ft lbs of torque to 15ft lbs of torque.
-I was impressed with the torque from around 3000 to 5000 as we gain around 15ft lbs of torque throughout.
We base lined stock with just an exhaust at 256HP and 190ft lbs of torque.
With the Topspeed headers we made 265HP and 198ft lbs of torque.
I was hoping to make 12 to 14hp but i am not dissapointed with the gains for the price. The Topspeed headers picked up about 9 to 10hp throughout and made around 8 to 9ft lbs of torque. For $625 shipped you can't touch it. You might be able to see a few more hp with a fujitsubo headers but expect to pay $2,200 and up. The welds of the fujitsubo headers are flawless! Wish i had the extra bucks.
Here are pics of the installation
All in all i was happy with the Topspeed headers. You can't beat the loss of 15 to 20lbs from the OEM header, the fitment, gains in horsepower, and the extra money left in your pocket. I personally recommend the Topspeed headers.

Congrats! Get it on the dyno! :smile:
By NA2 you are talking about a 3.2L motor? Chong's is a 3.0L in a '96.
