Yes without a tune or a spacer

Getting my AA today. Does anyone heat wrap them? 50' Titanium wrap isn't expensive at all, like $20. Will do mine.

I normally do all these modifications myself. I'm also waiting on the KW v3 coilovers and I'm doing it also. lol. I did the H&R springs like 2 month ago. Hell I even did the welding quad tips, been first timer welder. lol Only special tool needed for DP is the o2 sensor for like $10.

Did you not like the H&R springs?

They're fine and better than oem, but not happy with the drop so, only other option to lower it more was KW and it will be stiffer which I prefer in my Non DHP. Will go up for sales as soon as I take them off.

I just installed a racing dynamics HFC on my g05 40. The CEL turned on same day. I have the spacer. I also have race chip black. Can I reset with race chip or is the spacer not doing anything?

I nearly bought racing dynamics but guy told me it would throw a CEL.

You should be able to reset error message, however, it will pop up again.

Which catted downpipe would not throw a CEL for 40?

2SwiFt29 Typically any GESI cat.
Active Autowerke has one with great reviews. I have an SHS Autosport GESI catted downpipe that I will be installing soon and will make a before/after video, and be able to comment on no CEL. https://www.shsautosport.com/product...ipe-p541415346
Service has been absolutely stellar through chats with them so far.
You can use any b58 catted downpipe, hence it saying Supra above - but not all catted downpipes are created equal. Some will throw a CEL after some time, and are not a "high flow 49-state legal EPA approved GESI G-Sport Ultra High Output catalytic converter" like the one above.

Active autowerke with 4-6k miles.

Still available? If so, please DM me.

FYI, After 200 miles I got the CEL on the AA Catted DP. No bueno. Now, I'm not sure if these code are the regular one you get when installing DP as these AA DP shouldn't throw the CEL or it is actually something else rerated with the O2 sensors.

check out the LEIB MIL delete. Just ordered mine and installing ARM catless dp in a few weeks.

Got a link for the LEIB MIL delete?

[NYCX5M50i]

This is for M50i
A member on here has been running catless and this for a while with no issues.

CEL randomly with Catless here. A little annoying. Easy reset with JB4. Only reason I need it off is because the remote start wont work with the light on. . I tried spacers and it only changed the code that shows up. I may work on a better system. In theory the correct amount of voltage drop from the AF sensor to the DME should trick it into thinking the before and after sensors are reading enough of a difference, making it think the cats are doing their job. Trick will be finding out what that correct deviance is. I am sure I could get readings for a catted car and compare data. A little math and a potentiometer, and some trial and error, I think I could pull it off. Is it worth it, I dunno.
