im wanting to modify the shitty 2.0 collector on my dc sports header but need some advice.. should i go with a 2.25 or 2.5 collector? and if anyone has any pics of this mod that would help. this header is running into a apexi world sport exhaust. i think its close to 2.5 inch piping.

 

or does anyone know if its already on here somewhere?... thanks

 

ive decided to go with 2.25 to match the exhaust and delete my cat. i might post some pics if its worth anything to anyone in the future.

 

cat delete FTL.

It's a safe assumption that this is a DD.

 

Pollution, smell, cleanliness on bumper, sound, next-to-no power gain.

Take your pick.

 

Actually, the bike in my sig is a 4-stroke and it's sold.

 

I pick anyone who gives half a rat's *** about what they have between the pavement and their butt cheeks. A tuned honda pollutes less than a lot of "modern" pushrod V8's getting 10mpg lugging peoples' living rooms from stoplight to stoplight. A cat is a band-aid for poor/lazy/cheep engineering, and I see plenty of cars that fail emissions testing with them installed. My prelude passed emissions without one.
