  1. New Downpipe on the Market.

    Yes. I think it's a 9/16" or 5/8" that I used. Drill only deep enough so sensor will seat. You will see the minor diameter of the male threads on the fouler gets close to the drill bit size. If you go too deep with the 5/8" bit it may come thru. I then took a 3/8" or 1/2" drill bit and drilled...
  2. New Downpipe on the Market.

    I drilled it out to fit the sensor end of the O2 sensor. If not you can't get the sensor to screw into the fouler all the way. Also you need to drill all the way thru to make sure the sensor tip sees enough heat or it will throw a different code. It's a balance between cat efficiency code and...
  3. Tomei USA announces FULL TITANIUM MUFFLER for GR Supra

    I had a 1993 Supra TT and an HKS 4" Titanium exhaust. This Tomei sounds very similar to that HKS Titanium on my MKIV. This Tomei is not Honda like at all when you here it in person.
  4. A91 & Recent 2021 Impossible to Tune / ECU manufactured after 2020/6 is locked?

    It's an DME swap... They figured out how to code an unlocked DME to work in a car that originally had a locked DME. That seems to be how they tuned the locked DME car.
  5. FS Remark Exhaust : Elite Spec Cat-back Exhaust Titanium Tips

    Did you use it? Looks like it was never installed.
  6. Tomei USA announces FULL TITANIUM MUFFLER for GR Supra

    I got my Tomei dual installed. I have a 200 Cell race catted Downpipe hooked to it. On first start up it was INSANE.. Loudest most obnoxious exhaust I've ever heard from a non V8. It settles down once out of startup mode and then sounds mellow at idle. Give it gas quickly and it gets LOUD and...
  7. 2021 locked ECU JB+ users?

    Racechip or Titan Protune V1 are the best simple piggy back to do. Works like a lesser optioned JB4. Close to how the JB1 works but causes no CEL. You can get them used near your price range. It's similar to the JB2 if they made that. 😁
  8. SWIFT Springs AVAILABLE NOW!

    Can you PM me price shipped to NC.
  9. Eibach vs H&R vs HKS

    How much are you guys paying for install?
  10. A91 & Recent 2021 Impossible to Tune / ECU manufactured after 2020/6 is locked?

    Saw a guy on Facebook that said a guy in Russia had cracked the ECU lock. Might be true. If they can rig the election, then surely they can crack Bosch's little lock on the ECU. 😁
  11. Tomei USA announces FULL TITANIUM MUFFLER for GR Supra

    He has one single left. He sold 9 single and 10 dual ones today at XTR.
  12. Tomei USA announces FULL TITANIUM MUFFLER for GR Supra

    Yep. I ended up getting the last dual one they had at XTR Performance. Seems like too good of a deal to be true.
  13. Tomei USA announces FULL TITANIUM MUFFLER for GR Supra

    Looks like a winner. What time in 2022 will they be in stock?
  14. Fastest 93 octane stock turbo -1/4 mile???

    I think he's going to run corn... Thanks for all the replies.
  15. Fastest 93 octane stock turbo -1/4 mile???

    I was just asking/curious. A friend with a 2017 Grand Sport Vette (full bolt on & tune) and I were bench racing over text. He asked the question. I didn't know the answer. Mines that car. Stock turbo 2021, with catted Downpipe and Titan Protune, with HKS drop in. He runs low 11, high 10s, at...
  16. Fastest 93 octane stock turbo -1/4 mile???

    What is the fastest pump gas (non E85-E30) 1/4 mile time on stock turbo, with no meth? Other bolts ons are okay as long as stock fueling and stock turbo. Can Have: 1. Tune or Piggyback (JB4, Titan Protune, Racechip). 2. Downpipe, Catback, intake, drag radials etc. All okay Just curious.
  17. New Downpipe on the Market.

    I would not think so since it's not sensor 1 which is typically used for closed loop fueling feedback. I'm modifying the o2 responsible for catalyst monitor.
  18. New Downpipe on the Market.

    I have driven about 300 miles now. Many drive cycles. Drive cycle for me are 10-23 miles typically. Alot of cruising, some WOT blast also. No sign of the CEL. I believe it's fixed. So for the price plus $6 O2 fouler from Autozone, im very happy. Sounds perfect.
  19. New Downpipe on the Market.

    So as of right now I have driven 100+ miles and 6 or 8 drive cycles and have not gotten a CEL. I modified a Dorman 42002 spark plug anti fouler and installed between the O2 and the o2 bung on the downpipe.. Before the anti fouler spacer it would take 2 drive cycles and it was like clockwork the...
