At what cost? That is a great result for off-the shelf tuning.

Well... here we had a dude who sorted out off the shelf tunes to optimize with your current mods/fuel.

Edit: and the cost it was very affordable and fast delivery without cutting corners

Do you mean Wayne roms?

Im tempted to try the rom Stg 2 EL but there is not too much feedback with these headers.
I read the intake and exhaust cam timing is quite different from the OTS rom

Sure he can, and we got another guy as well

Updating this thread for those curious about what this header sounds like with an otherwise completely stock exhaust.

Still has a surprising amount of volume outside the car, but no more drone in the car like the old R400. Great success!

If I get bored of this, I think I’ll end up with the Fujitsubo Authorise S axle-back to maintain only slightly higher volume levels (~3dB on throttle) with a touch more tone.

If FedEx is to be believed I should be able to pick up and install my header this weekend.

I have a authorize S installed along with a 2.5" catted and resonated front pipe. Chance I'll be selling the axleback afterwards depending on whether it's too boomy or not.

Audio clips to follow.

Just saw your comment on my YouTube video.

I'm curious to hear clips, you'll love the header!

Got everything installed yesterday. Had an issue with the 2.5" overpipe contacting the subframe. Going to call on Monday to sort that out.

Sounds fantastic! Looks like I'll be going this route and pick up the Fujitsubo axleback come springtime.

I can try to get a drive by at some point. Only had it installed a few days while data logging for the tune.

Little to zero drone. My ears are pretty sensitive and I haven't been bothered windows down and rear seats up.
Same setup with punched out OEM header and gruppe-s UEL gave me instant headaches and ear pain.
