Will going down .1" exhaust piping diameter....cause bottlenecking?

[system]

I’d say go for the WS2. It’s hot as hell and like Bill said, you probably won’t even notice any difference. I was looking into that and the RS*R ExMag for my Integra both are awesome exhausts.

Yeah I’m picking up the WS2 fo sho, and my buddy is picking up the RS*R for his Civic SI.
