Ya.. i'm pretty new to CL, and I haven't owned my IS300 for long either. What I want to know is. Which headers wud u reccomend for an 03 IS300? I heard OBX is good but they are pretty pricey.

Also, wud I be able to install my own headers or is this a kind of thing that I have to take to a tuner shop?

 

Megan headers, you can do it yourself if you know your way around a tool box

 

I would go with Megan also. The only thing is that you have to reweld the o2 bung, which isnt hard.

 

I bought megan racing headers and I am very satisfied with them. I didn't even reweld the o2 bung. I just hit the engine bay with a hammer and made the sensor fit. Didn't damage anything =)

 

Wouldnt that make it look a little janky though? I dont know if I could bring myself to modify the car instead of the part

 

Hello, new members first post. Lots of knowledge.

If you do not want to get headers that require a reweld of the bung you can opt for OBX headers. They are basically turbo east replica's and weigh 3 pounds lighter and made out of sturdier metal. Only problem is you will pay more for them.

 

Tell that to my old OBX's which didnt fit and snapped in half when they were modified

 

Ahh that's right. OBX had long tube and short tube. The short tube I recommend.
