What are some of the quietest exhausts?

MikeySed · 03-10-2010, 07:39 PM

Not looking to have any drone, or anything. I would mate it up with HFCs ... what do you all think who have heard it in person? Using youtube is a hard evaluation. So I am asking people with experience who have heard or seen in person different exhausts.

I'd say the invidia gemini is one of the more quiet ones.

BERK Cat back is too, would work great with the HFC.

MikeySed · 03-10-2010, 08:38 PM

if I just added HFC to the stock exhaust with the stillen g3 intake -- would I be leaving a lot of hp on the table ?

Cause the stock exhaust mated to HFC (that works right?) would probably my idle sound..

in a seperate thread, Matt rated the Berks HFC with CBE combo as a 9 on a scale of 1-10 1 being not loud and 10 being too loud...

Stock exhaust with HFC is a pretty good combination. We have had a few people go back to stock exhaust+HFC after trying a CBE.

ahh really? But am I leaving 15-20 whp on the table? I was just reading a bunch of threads and dynos that show fi/stillen cbe making 15-20 whp, and invidia 8-10 whp..

20 whp is a good amount..

I mean I would love to stay stock exhaust/hfc, but don't want to leave a good amount of power on the table..

Chriz · 03-10-2010, 09:59 PM

Anybody have a clip of a stock exhaust with HFCs?

Drift Motion · 03-10-2010, 10:08 PM

+1 on stock exhaust...LOL

now for argument sake if you add a FI/Stillen cb... are you going to gain 15-20whp more?

No, it appears that the first opening up of the exhaust, whether it be HFC's, Test Pipes, or CBE, nets the most gains, you might see somewhere between 8-10, just speculation though.

Red370 · 03-10-2010, 10:47 PM

Most people that dyno with the HFC's add the intakes before finally adding the CBE or simultaneously, so there arent too many independent tests with just stock intakes w/ HFC's/CBE
