Stock!

It's amazing how much good flow changes the induction noise.

i drove my car for 400km since installation and mapping.. those headers are awesome! i suggest to check nut tightness after a wile because its impossible to reach three of them with an torque wrench. so doing it by hand in a small space may result in undertorqued nuts.

Put torque stripes on them!

Good info. I will check mine in a few weeks as well as I just got it installed!

After I installed mine, I left the car on stands with the underpanel off and heat cycled it a few times, then re-checked all the nuts.

I probably should have done that. Oh well, only takes a few minutes to get the under panel off and do it.

This is a great best practice for all parts, especially ones that see deep heat cycles and vibration like exhaust components!

Here it is Guys, took it to the dyno yesterday to tune the car with the header and this are the results;
1st pic is with the OFT v3.0 tune I had there before the header.

2nd is my tuner map

3rd is a run just after a few minutes of cool down and no tuning.

The most important thing I wanted to know is the Torque, but the guys at the dyno didn't connect the RPM signal wire to the coils.

No, weird right! Gotta be the header don't like the OFT tune. Or maybe heat soak? Like what happened in the last run where the car gained 5whp.
