i imagine theyre all the same length, use same cores, I hear the Stillen dont like being bolted to exhausts other than there own, fitment issues etc. Gains are similar for all. Pick a brand, thats basically it.

Actually, I don't think they are using the same cores.

FI uses 300 cell whereas Berk and AAM uses 200 cell cores. I'm not sure about the stillen though.

I'm not so sure the difference between 300 vs 200 cell cores can be felt or would make a big difference.

FI is slightly cheaper to buy, if that is a pulling factor!

interesting...so power gains are essentially equal and fi are cheaper and less likely to throw codes... seems like a no brainer then.

Are you planning to upgrade the CBE or have you already done so? If so, go with the same brand as the CBE to eliminate fitment issues. If not, it doesn't really matter (as far as performance gains). However, I do like F.I.'s craftsmanship and price.
