We'd say it can't hurt, but it isn't an absolute necessity. From our experience we haven't had any issues with our exhaust from people that drive it straight off the install or go straight to the dyno.

Anybody got their exhaust system installed yet? If so you are lucky! time to get some reviews in the exhaust section! woop woop! :happydance:

They tried to deliver mine today. I'm still out of town. :shakes head:
I'm having them hold it and I'll pick it up on my way home tomorrow.
I still won't be able to install it until sometime next week. :mad:
This is karma getting back at me for being so indecisive. :tup:

So I had my local Meineke today install it for $90... I think a pretty good deal since most performance shops wanted over $200 around here.

Looks: It fits our cut-outs in the bumper perfect and looks really nice. My right tip is probably a couple of mm's lower - not sure if it was partly from shipping or because Meineke did the install and didnt want to try adjusting it for me - it is def not as noticeable as the prior issues - I'll take some pics this weekend so you guys can be the judge. I'm a perfectionist when it comes to cars and it really doesn't bother me but I figured I'd bring it up before the pics show it.

Sound: It's actually much quieter than I expected - again I'm used to the TopSpeed with test pipes on the 350z so its obviously going to be quieter. I'm sure it has to break-in and will add some growl later on but I might need to get HFC's now. But I'll give it a couple of weeks before I purchase anything else. I'll get some sound clips this weekend as well.

So that's a little info from my short time driving it today in between work.

Good deal, post some pics so we can take a look at the alignment and maybe give you some pointers on how to tweak/fine tune it.

I just had a quick thought about break-in on the mufflers: FI uses straight through glass pack mufflers. These are literally packed with a fiberglass material to halo muffle the sound. From the looks of it, the Berk uses a type which has chambers that cause the audio waves of the exhaust to bounce off the chambers and into each other, canceling themselves out to an extent. It is possible that without a few cycles that the FI style glass packs would not seat properly and you could eventually blow the glass right out of the muffler, although I have not heard of this happening. The Berk exhaust should not require "breaking in". I also could be very wrong about everything I said. What do I know? I'm just a mechanical engineer :P

Very Good info and explaination...:tiphat: It makes more sense the then the explaination that was given in the FI thread....Your explaination acutally paints a picture of why the FI Exhaust would need to go through the break-in period :tup:

everything I've ever read about glass-packed exhausts (at least on bikes) indicates that glass packs need to be replaced over time...

Glad I didn't go with FI.

I picked mine up today. I posted a quick review here... http://www.the370z.com/intake-exhaus...s-reviews.html

I just have a few questions...

What the hell are these? Are they important? If so, then I am missing one bolt. :tup: What was in that Box?

I just opened up my box and didn't see anything like that in there. I'm going to double check through all that packing paper again.

UPS dropped it off yesterday, AS i was walking out my door to go to work. installs on tuesday, cant wait.

Looks like extra junk got into your box, mate.

I am installing mine tomorrow first thing. Was it worth the wait??? Probably.

Yeah. That's what I figured. It's better than not enough stuff. :icon17:

UPS tried to drop mine off Friday but ko one was available to sign for it. Means I have to reschedule my dyno appointment for later in the week. :(
