I have a 98 civic hatchback thats gonna be having a built b20vtec going in it. and i have been wondering what size exhaust should i run. im gonna be putting a buddy club spec 2 exhaust and maybe a kiddracing narrow header. Lmk your thoughts

 

3"

 

that buddy club shek 2 will gtfd.....lol anyway are you staying NA or what?

 

regardless 3"

 

yes im staying all motor

 

3" would be my choice.

 

you dont think it will run like crap or a lack of back pressure

 

10"

 

3 inch

 

3 inch if its built youl be fine

 

That's just a myth that I kinda thought was true too, until recently.
