2M Fabrications Review (Headers)

[Selim K]

It's not crank relear it's the O2 sensor. Probably need to replace that one. I use Lund and have read they don't tune for headers.

Lund does tune for headers. They just don’t disable the CEL because of the EPA. Car will run perfect, you will just have the light.

Also, I installed my 2m headers back in November last year . Good quality and good fit. Was a pain in the ass to put in like any header. USE THE OEM GASKET! They are multi layer steel and good quality.
6k miles no issues other than my o2 sensor just shat itself the other day. I been on e85.

Ya I’m hoping that’s not the case but I want to double check that as well as check bolts and leaks before giving a final review.

Any Feedback reviews Yet?

Well my engine blew so I’m going to have to pull it. Looks like one of the bolts backed out completely and fell out and another one backed out partially.

defiantly recommend retightening the bolts after a couple hundred miles.

Sorry to hear about your engine. Have you discovered what caused the engine failure?

Probably mixture of bad tune and bad luck. Piston and spark plug melted. Either car didn’t fuel correct properly and the car went lean or the piston ring gave out and car went lean. Those are my best ideas.
