Don't guess like an idiot. If you've heard both, CATLESS, which do you think is louder?

hush sounds louder catless, imo.

 

Greddy is louder to my ears

Blitz!

 

Low tones - Hush (closer to porsche race car)

High tones - Greddy (higher pitched F&F sound)

Of course if you WANTED a little louder you could remove the baffles 2 small ones in the Greddy and 1 bigger one in Hush

austin,

so you mean the hush is louder at low rpms and the greddy is louder at high rpms?

 

Honestly, there isn't much difference if any between the two exhausts (Borla Hush vs. Greddy Evo). A good person to ask would be DJTEN4 since he had both exhausts systems in his car mated to the Helix up/downpipe combo. However, he's in Europe for the next couple of weeks.

Borla Hush sounds almost stock at idle, but when you open it up it gets fairly loud in a deep way, almost like a Porsche.
Greddy Evo has a bit more resonance at idle, and when you open it up it too will become fairly loud, but in a slightly higher pitch. Reminds me of a man screaming as he's thrown off a cliff
But I say keep the HKS Jason!

 

the Hush sounds awsome at idle.(catless anyways) its a lot deeper sounding the stock

 

MMBoost-
Like I said, at the top end the Greddy has more of a scream and gets kinda drony really quick on the freeway. The hush keeps a low, low deep tone through out the entire RPM range.
