I want to know what is the most power i can push out with stock exhaust and HFC? w/o having to upgrade the exhaust

My mods
SOS stg 1 1220 Non-SL
SOS TB
Berk Header
Stock exhaust
Stock Cat

Im debating to ordering a HFC from Berk.
I previously had the 3in header-back exhaust but it was way to loud for my taste.

The Berk HFC is a really nice piece....! Plus it's a lot lighter.

If you're not going to upgrade the exhaust....you're going to need one sooner or later anyway. The added heat and vibration from the supercharger will eventually cause the internal mesh of the OEM cat to break free...then rattle around until it smashes the crap out of the sensor installed on the side of the cat.....then you'll have to flip for both (1) the new Berk HFC and (2) a replacement sensor that will set you back another $150+

Found out the hard way about two years ago.....

wut about a invidia test pipe w/ CEL fix.

Thats what i have & love it.
Exhaust is just as quiet as with the OEM cat but it flows freely.
You can get a test pipe for $50 compared to spending $250 on a HFC that doesn't flow as well, no brainier IMO.
