Will the above fit on my ex?

Is the piping larger?
Will it be worth it?
I'm looking for a better breathing exhaust .
Don't want anything loud.
Ive had the WS II on another car. Nice but pricey.
Not looking to advertise either.
Also considered a 2002 or so rsx type S stock exhaust.
Any ideas?
I've searched seems like the si should fit.

 

IIRC 92-00 exhuasts are the same coupe to coupe sedan to sedan

 

I checked on majestic Honda. They list different part numbers for the ex and si in 00 model year. I thought since the si was a dohc engine it should have a better flowing exhaust system.

 

its not really a matter if it'll fit .. since you can pretty much weld anything to it .. i think the SI exhaust should fit but you might have to use some part of your stock one

i got ctr mid pip with gsr muffler on my 96 HB DX .. chopped and weld

:D
