Exactly what you need 🤣 if you need to watch him thread bolts in you shouldn’t be installing headers

@@masonspears2764Installing headers in the E46 is a PITA so, yes a full install explanation is necessary.

EU2 performance tune.. Look up Kassel Performance.

catless header will be very very loud, only way to cut the noise down with catless headers is to keep your resonator and muffler on the exhaust system, so that means no straight piping your exhaust system

i installed spacers before the post-cat sensor, so that the sensor is no longer in direct flow of the exhaust fumes, and that eliminated the cel

BackyardWrenchin interesting and this works for a BMW E46? And you had no further issues? I plan on doing same thing to my E46

no further issues

BackyardWrenchin where did you get the elbow spacer and also what brand of headers are they? eBay?

+Juan Rivera yea some were tough , be careful not to strip them

And tires

+RJ4evr lol e46 life bro

Use a bunch of spray lubricant, loosen slowly so you dont snap a stud that may be seized in there

good luck fitting a torque wrench, you would need to pull the motor

+Jason I had to cut my exhaust flange, rotate it and have it re-welded because i was sent the 330/325i headers instead of the 328i/323i headers where the exhaust flange connecting the header to the rest of the exhaust is oriented differently. I had to cut and rotate so that the holes for the bolts match up. By exhaust leak, i meant that the headers were not yet connected to the rest of the exhaust piping. Just make sure you get the right header for your car, and you wont have to worry about this.

+BackyardWrenchin got it. Once more thing. Did you wrap the headers?

I didn't wrap mine, but its always better to wrap them.

+BackyardWrenchin why is it better to wrap them?

Less heat dissipation into the engine bay. That's always a good thing.

+BarberKid Yep as long as the post cat sensors are far enough from the exhaust stream you wont get a check engine light and you will pass.

The o2 sensor bung locations were not ideal on mine, but they still fit. The welds are nice. I think its a hit or miss, since there's multiple sellers for these on ebay. I got mine from cali, would'nt recommend the ones from china.
