HFC's only?

Bodytechz · 02-09-2011, 03:43 PM

Would I get an HP increase by adding only HFC's alone and would it increase my exhaust note as well? Not looking for excessively loud exhausts just a little more "Rumble" than stock. Also looking at adding HPS post MAF tubes. Thanks in advance!

I was running with just HFC's for about 5 months before I got my CBE.
I noticed a nice bump in power and a more aggressive sound as well. It was louder but not obnoxious.

If you are looking for a set of HFC's let me know. I have a lightly used pair of Berk's for sale.

Would someone be able to pass an emissions test with HFC's ?

Yep, in fact many new cars could technically pass emissions with test pipes as the engines are clean and efficient enough.

Well then, HFC's just made my list then.. I would hate to have to replace
with the stock cats every year just to pass emissions...

Here in TX we have exhaust emissions testing for vehicle inspection..
