Emira Build Questions

[phizy]

Hey Everyone, I recently just pushed my chapman edition over 5k miles and I am looking to do some modifications. I wanted to get some advice and opinions from everyone who has done similar things. My main concern at the moment is headers and exhaust, I was going to get the valvetronic exhaust but then saw the QA issues and realized the video was with headers as well. Has anyone solved headers with CEL yet? if not can i get that tuned out by my jb4? (JB4 is on the way as well) As far as exhaust goes whats the take on GRP vs Larini? Titanium vs Steel I suppose?

Outside of headers and exhaust I have eventuri carbon intake bookmarked is that solid? (I havent heard anything negative about it or positive other then an intake helps a lot.)

Suspension anyone have any recommendations for lowering? (I lowered my '20 Supra on springs and hated how bouncy it was but loved the fitment achieved any input here would be greatly appreciated)

Best

I don’t believe jb4 will prevent CEL, just allow you to constantly clear the codes. I think vf tuner is the only ones doing tuning for the v6 ecus, maybe komotec too.

As for which exhaust header combo, it’s best to listen in person and decide from that. I think most people here think just doing a 3rd cat delete is enough to get a good sound and not have to deal with CEL by doing headers

I think most people here go with nitrons, you probably want to ask Greg at grp for some recommended spring rates as I hear he also has a Chapman edition emira.
