370Z exhaust system FI carbon fibre CRAZY NOTES!!!!
If your looking for an exhaust system??? you really need to watch this:happydance:

Please make another at cruising speeds? That sounds awesome, and I'd be sold if I knew it didn't sound horrendous when out on the highway.

In all truth 100% no bull, when im cruising @100kms\60mph I cant hear nothing. there is a minor bass tone and that's it, even cruising in 4th gear, there is no sound on the inside. I'll make a video.
on hard acceleration, yes she is loud but more on the deep bass side with zero & I mean zero rasp.
when cruising, its 5% louder than stock.

Looking for a new exhaust
 

Guys I need your feedback.

I installed the F.I. non-res catback + non-res testpipes and loved it until the rasp and hiss started to get to me. So I call Tony at F.I. and he suggested to add resonators to the catback so he sent the 12" res to switch with the non-res Xpipe.

It brought down the exhaust note but barely did anything to the rasp and hiss. I love the F.I. exhaust but I need a change.

I was looking into several exhausts and was hoping those of you who have these exhausts would give me some feedback on the sound and performance so I could choose properly.

I was looking into:

HKS hi-power
Greddy Ti-C
Greddy Evo3
Greddy SP
Injen CBE

I would appreciate it if you would give some comments regarding those exhausts.

Thank you

All exhaust will have some rasp and hiss with test pipes. Nature of the beast. Some say the m370 manifold can reduce rasp as well.

If you don't want rasp or hiss throw the stock cats back on or get resonated test pipes or hfc.

How come no one looks into the MXP true dual exhaust. Maybe there's something I don't know, but I purchased it, and not only does it look good but it sounds great as well. A little less aggressive than I thought but whoever hears me go WOT gives their mark of approval. I'll post some videos when I get a chance.

^^ I actually did look at MXP but I wasn't too sure about quality of sound. How is the MXP? I'm planning to keep my testpipes so I need to combine that with an exhaust that'll give minimum of rasp.

I like it a lot. I've never had a raspy exhaust so I couldn't tell you if mine is. I do know I like how it sounds a lot. it doesn't drone in the cabin. Hell, if it's a warm start you would barely be able to tell it was on at idle. But on acceleration I've gotten head turns, nods, straight up compliments at lights. So... I'll get a good video posted and I'll let you guys decide.

It probably isn't as aggressive as the FI or the other ones. I'd say it's a little more aggressive than the Stillen exhaust. But then again I liked the stillen exhaust as well, just wanted something a little more aggressive.

I like my exhaust to be loud, aggressive and crisp. I might have to change my testpipes for Art pipes after I choose a new exhaust.

Remove your test pipes and install high flow cats. That's y u have the rasp. I have F>I HFC + CDE non res and I have zero rasp at any rpm.
(check my video at the top of this page)

what are your guys thoughts about the Greddy EVO3 ?

I have just purchased a Hi-Tech exhaust for my 307Z and it is fantastic !

Take a sound clip ?
