Ordering an I'm exhaust of rock auto for quietness. 1990 accord ex sedan.

Do I need the 14" or 13" catalytic converter? Guessing. the 14" since it's a sedan. Though in the description it says sedan or coupe for both options so I'm not sure which one to order. My current exhaust is all welded so I can't accurately measure what size it should be. Is there a way to tell by the Vin?

Also they have the value line bosal vs the regular. Are the value line materials complete garbage? I don't want my new exhaust rusting out in 1 year.
Getting this cb7 running like new!

Roh conversion complete!
Rear disc conversion complete!
Beginning a suspension overhaul as well. Should I get a bulk polyurethane bushing kit that comes with all of them? Any tips on shocks/struts? Looking for as smooth a ride as humanly possible. Best cornering as well.

Thanks in advance for any help !

 

You're going to have to give up on one of these.

 

I figured as much guessing oem is my only option for smooth and quality since everything else tightens up the turns while loosing smoothness.

No one know about these 14" or 13" cats
