You have the Fabspeed extender and no CEL? I got downpipe installed yesterday and now have a CEL. Is it possible to switch out an extender without having to dropping take out downpipe? From the bottom perhaps?
I put on the Titan Tune yesterday. I have the downpipe as well but haven’t put it on. On map 3 it is already a beast. Traction is an issue lol. Can’t wait to throw downpipe on and use a different map.
On the M3/4 there was a gray “charcoal” filter on top of the drop in filters. I suspected the Supra also had it, and indeed it did. It’s a small gray filter in the bottom. I took them out in both an M3 and M4. It’s for emissions or something idk lol ‍♂️ Anyway the turbo noise is more pronounced.
Has anyone put on air intake or a K&N air filter? I put on the HKS air filter on today. I don’t know is it’s placebo but I swear you can hear the turbo much better. I also took out the charcoal filter that goes under the air filter, which I remember made a difference in the F80 M3.
You could probably get away with sticking the 13mm in the front. I personally wouldn’t go too big in the front. In the back you could go 20mm. Not a real difference in ride or handling.
