You never want to choke down as you move downstream of the exhaust flow.

2.5" all the way through if you're using the JDM DC Sports header.

The Spoon N1 is 2.36" (60mm), like 95% of the JDM catback exhausts.

spoon n1 is 2.38mm man !!

i think 2.5 is to big for 1.8 L ...

With all due respect, your thinking is flawed.

no

Spoon N1 is 2.38" not mm, and most of them have a bottleneck down smaller than that where it joins the b-pipe.

A few guys by the name Dave Stadulis, John Grudynski, and Danny Tran would disagree with you on that one.... https://honda-tech.com/forums/images/smilies/emwink.gif
