Dyno shows Popcharger gained more power....I am replacing my AEM with the JWT pop. AEM is not hard to change nuckle scrape or two.

 

What is best to do first, cold instake or exhaust

 

Wow. Props for search negative for everything else. But I'd choose cold exhaust instake

 

None of these intakes provide any significant gains. This is an interesting thread (see below) about the topic, kind of a long read but worth it. A clean oem filter and intake is superior in terms of gains/filtering efficiency.
