Just think it's not hissing at you, but at the cars around you...

YES, i just had mine taken off and like it MUCH better

The hiss is no good. Honestly, I think the 18" CBE sounds perfect. The best way I can describe it is as 2003 Cobra with HFC X-pipe and Magnaflow CBE meets Ferrari F355. Nice and deep rumble at low RPMs which transitions into that mid-range howl the Ford 4.6L's all have and then the higher pitched scream from the F355 at the top of the range.

so by your methodology....i drive a pissed off Ferrari

i can dig it

DannyGT · 09-28-2009, 01:27 PM

No...The hiss will come from any test pipe...and to answer one of the posts above me, its not being caused by a particular design flaw, its actually a harmonic resonance (think, frequency) that caused this sound at different rpms. I went threw a long drawn out process and the sound while being caused by test pipes, could almost be felt in the area where most X/Y configs meet. It was very odd, but that resonance was definitly caused by the test pipes.

Usually, between 2-3k while on the gas you can get a hiss/metalic zing/flutter type of sound, very very annoying in my book. Also, on decel during those same rpms, its just a straight hiss...

When I changed from the berk non-res test pipes to the GTM resonated ones it dramatically reduced the sound. In fact, I dont get that rattle on accel anymore, just a slight hiss on decel around 2500rpms.

From what I can tell, it may be possible to kill the sound all together by using those FI pipes that had a HFC & resonator all in one...I also heard that a true-dual exhaust with no connection (h/x/y) doesnt make the sound either. But it also doesnt make good power compared to a nice X setup.

all i know is that i hope that the cbe + long tube headers will create bigger and larger power gains vs. cbe + hfc/test pipes

and ofcourse have a sexier RAWR to the sound note

It should no problem.

Working on getting some in-cabin video processed so I can upload. Went for a casual cruise this evening so I could give you guys an idea of what the 18" res CBE is like.

m4a1mustang · 09-28-2009, 09:37 PM

Onboard video from today... Video is finished processing so the high quality version is available.

Just some casual driving... never got it over 5500.

Hi Steve, is there any sign of drone/hum in the cabin at any rpm when cruising?

m4a1mustang · 09-28-2009, 09:57 PM

It's more of just a very deep rumble than drone. On the freeway the exhaust doesn't get loud unless you are giving it throttle. At 65mph in 6th gear you're pulling about 2,500 RPM and it's very comfortable.

I'm going on a trip this weekend that includes about 4.5 hours of freeway driving each way, so I'll report back with how I think the exhaust does on long trips.

Hey, thank you man! Like Steve said, you make an amazing product of top-notch quality. I am IN LOVE with my car all over again that I just want to drive it non-stop. Revving it out is just so beautiful. I have received many compliments on the sound and looks. Thanks again!

Rob

I really will do my best to get videos up this weekend. Just been busy - work from 8a-5p and then class from 6p-9p. I don't get in the door until nearly 10 each night, so weekends are all I have.

Again, all I can say in the meantime is to brag on the perfect fitment, and both beautiful sound and looks that will turn heads. The car is a true pleasure to drive now, more so than ever.

m4a1mustang · 09-28-2009, 10:02 PM

Big thanks to you, Tony! Awesome product, great quality. I should have listened to you the first time when you told me just to buy the 18" CBE. I just had to call back a few weeks later and add the HFCs that I'm not even going to use! The CBE alone is perfect!
