Anyone know the pipe size for a 90 accord? I just need to know the stock size i don't have money for exhaust now so i might get a high flow cat. Thanks

 

don't even worry about a high flow cat. just go with a test pipe. they cost at the most only half as much as a high flow, should make more power, and if you're worried about emissions it only takes about 10-15min to switch back to your stock cat.

 

its between 1.9"-2" ID

 

and the o2 sensor housing and stock collector on the header is 1.5" ive measured it

 

1.4" on the lx

 

its absolutelly pathetic isnt it?

well hopefully ill secure enough funds to get some sort of vtec controller, damn hondata tuning is going to cost too much (well ill see) but i digress i wonder how much it freed things up....

off the wall thought
now that im thinking i wonder where using the stock jdm h23a rods on the f22b1 pistons would put it in regards to CR and r/s i guess it would share the same r/s as the h23a as well 1.49 is still kinda *Blech*

 

the diameter is about an 1" 7/8

 

I was actually ordering a test pipe but most people think its messed up and i wanted to know the size. For the 4th gen accord they list a 2.25" and a 2.0" and i wanted to know which one worked best. I am thinking the 2.0" but i am really not sure. its on testpipes.com or whatever it is. Thanks for the help

The only reason i am doing this is because i have an h22 swap and the exhaust is damn restrictive but i do not want some huge noise maker that i can not afford anway i like people thinkin they got whooped by a stock accord lx.
