that's B-series thinking... they also said that about a stock Si (2006+) with a 3" exhaust... the 3" improved overall power and peak power for that engine... and even WITH PROOF ppl were still saying that the 3" was too big b/c they had it stuck in their head that smaller was better for low-end torque... fact is 3" piping made more hp but like 3tq less than a 2.5" personally i'd sacrifice 3tq to gain +10hp...
the 1.5 LEA1 is no K20Z3 but keep in mind, getting into the higher rpms is where you need higher flow... down low you need the smaller piping for the back pressure but the CR-Z has the IMA to help down low... so up top would benefit more from a slightly larger exhaust... what is stock piping??
if not 2.5" at least 2.25" with two resonators... i personally wouldn't buy a smaller exhaust than that...

i know what u mean... if the resources are there, why not make one... if it's too much trouble then just go with what you have... i'm a person of perfection so, i will push and push until i have the limits...
one major thing when thinking about the CR-Z is the IMA is gonna help down low NO MATTER WHAT... so anything i would make would be for upper gains taking priority... for example: a SRI has much better response for down low power but loses it up top mostly b/c of heat... a CAI would be more beneficial on this car, i think, b/c of the IMA boost down low and when it gets to the higher rpms, the CAI will make more power... does any of that make sense?? i don't have a CR-Z... i'm just using my logic here...
