    FS - ETS full 4" GESI catted downpipe (NIB) - $800 shipped

    you won’t get a CEL with a GESI catted downpipe. There are a few 4” exhaust options, or any exhaust OEM-style could be easily modified by a shop.

    FS - ETS full 4" GESI catted downpipe (NIB) - $800 shipped

    Did you ever research on people getting CEL's with this DP? Interested, but only have the JB4 and don't want to deal with a CEL. Which exhaust did you plan to run with it?

  4. Any info about the Artisan Spirits Ti Exhaust?

    This is what I am leaning towards + AA DP. Still shopping around.

  5. Any info about the Artisan Spirits Ti Exhaust?

    5 grand, probably sounds okay with the stock downpipe and probably really loud with an aftermarket dp. Probably drones quite a bit as well. For 5 grand you can get a top tier full exhaust (catted DP and an AWE touring), lowering springs, and a JB4. Heck then buy a nice car wash kit with a foam...

    Just got my jb4 last night and I did map 2 group log with cruising and a couple of pulls, I know it’s not a wot 3rd gear but I was hoping you can check if everything looks good. Mods cts catless downpipe cts intake exhaust...

  8. BM3 vs JB4

    That was well written my friend. I appreciate the detailed information without belittling me. Thank you.

  9. BM3 vs JB4

    Bern77, i'm going to try to prevent you from getting absolutely flamed on here by the savages that haven't eaten in days. JB4 works on any car, it's simple and just tricks the DME into allowing more boost (amount depends on the map). There is a guy Jesse on the forums here that will do a...

  10. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Happy I found this thread. I had a 22 AT with boostlogic catless DP, exhaust, hks intake and JB4 on map2 93oct and car ran amazing. Traded in on a 24 MT, been waiting to see some good news before I hung all my parts on the new car. Thanks everyone for all the work, looking forward to helping...

  11. Another tire post lol

    I haven’t tried the Nittos, but I currently have Firehawk Indy’s on my car. They are great for the price, but not quite as good as the stock MPSS’s (which are fairly compromised tires in my opinion). FWIW, I got them late last summer for my stock wheels so I can drive the car in spring/fall...

  12. Another tire post lol

    Running square setup. No tracking. Just highway pulls and stop sign digs. No tune, just JB4 and exhaust. Between these two because my cousin can get a deal on either. I’m in CA not worried about weather other than rain but never crazy. Nitto NT555 GT or Firehawky Indy 500 275/35/1

  13. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Few Map 2 logs with above adjustments (screenshot below). Felt even better and much more dialed in like stock/pre DP - thank you! Map 2 adjusted v1 Map 2 adjusted v2 It was the exhaust valve being open vs. closed on cold start - thanks again!

  14. Curious about downpipe.

    First of all this is my first message to anyone in this thread. I recently got a 2023 gr supra 2 weeks ago and absolutely love it. In the Socal area do the owners here have any modifications to theirs and if so what ones? Alot of the things ive seen are downpipes, jb4, air intakes, or exhausts...

  15. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Almost certainly the JB4 exhaust flap control is opening on cold start. Whereas OEM mode keeps valve closed until cold start is finished. Glad I could help!

  16. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Thank you for the quick feedback - will make the changes and will run/post new log! Completely understand there shouldn't be any changes regarding louder/raspier exhaust from JB4... but I installed the DP in December - I'm used to the louder/raspier sound (louder cold/hot starts ... LOVE the...

  17. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    ...As for the louder and raspier exhaust, that is just from the downpipe. JB4 is essentially inactive at idle. It is possible that the JB4 exhaust flap control is activating on cold start (mine does it). you can adjust that by holding the BC button on the turn signal stalk. switch between...

  18. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Hi all! 2023 3.0 AT Prem, catless DP (Armytrix) and intake are the only aftermarket performance mods (well, intake for the sound ... but thought I'd still mention ;)). Post DP install, I immediately noticed lack of rear wheel traction in 1st through 3rd with WOT - main reason I picked up JB4...

  19. B58 JB Plus Quick Install Tuner ....

    You can "tune" the jb4 and get a custom map. Not as extensive as what you can do with a full tune, but custom jb4 smooths alot of things out.

  20. B58 JB Plus Quick Install Tuner ....

    I started on a conservative 2pm setting for a few months and then went up to the 3pm setting more recently. I really can't fault the JB+ to be honest: Reasonable little bump for minimal cost and fuss. MT running 93 (98RON) exclusively. And while it might just be placebo, in Sport mode with the...
