So I've got the stock frontpipe, e85 stage 2 oft tune with some tweaks and a catless UEL, have had friends follow behind with no issues. Even at full throttle, same with 93 octane tune, the cat in the front pipe really is more than enough at temperature and it depends on how you adjust your tune. It's really important you have a tune that's sort of around 14.7-15.3 afr in closed loop fueling. Also in the cold it helps to return the "loud cold start" it would help heat that secondary cat up. The smell and noise issues are so varying depending on tune to tune and even car to car.

Fix the oil temps, not the header. Our cars have issues with under hood temps all around. Do you have an oil cooler? Try a good one of those first. And add vents to your hood as well. |

No change in oil temps, Tomei UEL, a small bit of heat sheilding on the front face on the sump only.
I have replaced the OEM stone trays as well.

You just have the tomei and a tune If not what other mods? What was ambient temp? How are you measuring the oil temps? Are you on stock 0w-20? Altitude? Highly recommend you do the following if those are your temps after just 20 minutes, as switching from uel to el will make no difference: 1. Edit your fan curves as was posted in a past tuning thread to keep the engine bay vented better (can find the post if you need it probably) 2. Invest in a thermostatic oil cooler 3. Ceramic coat the UELs (last effort) 4. Get a heat shield for the oil pan if need be, but Tomei and Gruppe both offered a heat shield for the oil pan (last effort) It's relatively normal to reach 237-245 at full tilt on track/autox on a stock car, your goal should be 185-220 range, as the temps you are getting are track/auto-x temps that I got before an oil cooler.
