Hey, I have the Ver2 Tomei UEL header. Personally I don't have my car dyno tuned so I unfortunately cant give you any data on it. I sold my JDL catted UEL Cerakoted header to get it and if it means anything - I raced my buddies Tuned VB WRX (Cobb Tuning and Perrin Intake) on the highway and I beat him every time rolling from 3rd at 40mph and up. Granted, I was on ~E70 (Delicious Flex Fuel Kit) and he was on regular California 91.

I believe the flex fuel did most the work there perhaps, but in combination of the new Tomei header, Stock OP, JDL dual resonated FP, and Apexi N1-X catback. I would say performance blew me away. I switched from JDL because I wanted more of a UEL sounds because Catted JDL makes it "Less" UEL if that makes sense

Hey, great info and I’m glad that the rumble is more pronounced with the uel tomei ver 2 compared to the catted one. I’m assuming you’re tuned using the ecutec phone flash and your tuner just sends you the file? Do you also have the quieter cold start?

Yes, tuned by Delicious Tuning using Ecutek phone flash. They'll walk you through everything. Actually when it comes to the cold start - They did adjust it when I first got tuned, but it lowkey sounds the same to me as stock. Its still loud for some reason and I asked them to adjust it but they said they are unable to further tweak the cold start. That's my one gripe about the tune because it cold starts at around ~1,500-2,000 RPMs. Will probably contact them again about it

The cold start delete is frowned upon for emissions reasons. Cobb\Ecutek (sister companies) and their project green speed have committed to "fall in line" and not allow features that blatantly violate emissions compliance. That doesn't mean it cant be done, but businesses found in violation of these laws in the US have been shut down and ordered to pay hundreds thousands of dollars. Tuners also risk having their license taken away by Cobb\Ecutek. Something as simple as tuning off a CEL for not having a cat can open an irreversible can of worms. If you find a place to honor your request I would do them the favor of not advertising it.

Yep, just checked Delicious Tuning's website. Looks like this "Green Speed" project took place around February of this year and has since been implemented. I'd like to mention I got tuned by them before these new rules were set in place last year in 2024.

Thanks for letting us know. Delicious Tuning has been in compliance within my experience with them personally.
