Hi guys, I currently have a Vortech setup on my G pushing 380hp at 9lb boost. I am currently running on a stock exhaust system but am looking to upgrade. I tried looking around and didn't see much before and after results for exhaust mods on FI cars (my350 down atm ). Can anyone give me some insight on what kind of gains I would see from adding any of the following: headers, hi flow cats, and a true dual catback. Also, any idea of how much boost is lost with the mods? Thanks in advance

 

best bet would be check with sentry or booger.they can give you the best answers.

 

yup PM either one of them.
