just curious of difference of flow between the two...how many CEL is stock....?

any good relatively cheap options?

so far i've been leaning towars depo racing....its 189.99 and its 200 CEL...

i live in IL so need to be able to pass emissions so test pipe is out...sticking to OEM downpipe and cat-back exhaust...thanks guys!

 

Stock Cats are usually around 400 cell. I bought my HFC from Mil.Spec and it's been great, 175 cell, no check engine light, and made in U.S.A.....

 

Slee, did you custom tune? or Flash a GST Map? or still running stock?

 

i got the AMS metal HFC and im not running any CEL's under GST basemaps. i installed the O2 Spacer at install but that was throwing a code, took it off, cleared right up.

 

Check my "signature" and you'll see.
