I really miss the boom of my Greddy's. But like you, I still never got over the angled rear section. The Greddy tips are pretty big, they just look smaller in pics. If you're looking for just sound, get the Greddy. But for overall performance and looks definitely the HKS.

 

Mines def the loudest. People can hear me multiple roads away. I have FI catback with FI non-res TPs

 

brian thats because you have test pipes..

the greddy with test pipes would be ridiculous.

but ur FI exhaust with nothing else vs. the greddy exhaust w/o silencers and nothing else, the greddy is much louder

 

performance? you have a dyno sheet for the HKS?

 

you guys forget about borla?

 

Nope, waiting to get HFC's & tune before I dyno.

 

how much louder is greddy compared to the HKS? and how is the HKS compared to Stock (loudness)

 

stop asking all these questions and come to bk to hear it..although i have HFC's now.

also the greddy without silencers is a lot louder. at idle you hear it purring and humming, HKS at idle u cant hear anything

 

speaking of loud exhausts... I literally just put on the CF FI exhaust 2 hours ago, and I can't imagine anything being louder. Its so loud, I'm questioning on whether to take it off and sell it because it gave me a pounding headache from the noise driving it home. I have headers and HFC so I'm sure that doesn't help the situation but $%*&!!!! I couldn't hear the radio at crusing speed on the freeway!! I'm seriously not pleased.

 

^^^ wow headers + hfcs? that makes it loud as hell, FI isn't THAT loud imo... but since you have headers and hfcs... it must be loud as crap...

 

wat kinda headers? stillen im assuming?

 

yeah I have the stillen headers and their cats.... In FI's defense, I did have my rear seat down to bring my stock exhaust home so it reduced the sound barrier between the cabin and the mufflers when I was driving home. After I unloaded the car, I took it for a very very short spin around the block with the seats back up, and it did help a bit, but its still ridiculous. It sounds great when its idiling, but once you hit the throttle it absolutley screams. At WOT I can't tell if it sounds good or like a honda civic potato shooter. The low frequencies are whats killing me, its like a 100hz drone at 100db. I'll take an in and outside cabin video later...

 

^ you'll love the sound later, let it break in a little

 

yeah yeah yeah what ever mine is louder hahaha i set car alarms off. hahaha..dam i cant wait to drive it again....

 

+1 on that Borla + HFC's = serious sound
