i was wondering for my H23 prelude wether i should go w/ the 2 1/4 or 2 1/2, im going to get the apexi n1 muffler with it...but just seein which would be better.

 

go with 2.5 inch.....2.25 is stock size....your h23 makes plenty of exhaust to fill up 2.5 pipes....

 

thank ya

really? i didn't know that the si came with 2 1/4 piping stock...

 

i think its 2 inch....dats what i used for my straight piping....not a very smart idea...its way too little...i think 2 1/2 is perfect.

 

2 1/2 is perfect
