i had those with no cats on my car for ooooo... about 15 min. then i took them off and sold them for a true catback. the noise is insane with test pipes and short tails. no joke, it'll make your ears bleed

Yep, That's with K&N drop-ins and Z1 post MAF tubes on the intake side and just the axle back for the exhaust side.

I have a friend who has just got his test pipes and will be ordering these soon. Edub, is it just louder than it would be with cats, or does it change the exhaust note as well?

That is really loud. You should get some vids from outside.

Not a bad idea LakeShow, I also have an idea for how to get a good exterior recording of the exhaust once I have some daylight although I may try preliminary testing tonight...

sounds good :)

when you have the short tails and then add test pipes/headers it gets very loud and not a good loud at that. As far as doing headers I would suggest not going that route not worth the money vs the gain (plus a pain in the butt if you do it yourself). HFC is enough to get the performance you want and keep the sound IMHO. a headers/HFC setup will only work for you if you go with a SC and a CATBACK exhaust. If you like the sound and just want to free up the exhaust here is what to do get yourself a ypipe and midpipe (nismo exhaust works well for this) In fact I am getting my car back this week and I will have the ypipe and mid pipe for sale here soon HINT HINT. That will give you a great sounding setup and some performance to boot with those short tails. I wish I had video of that setup before I put headers and cats on but I didnt. Good luck with the build I like your direction. :tup:

I think that may be a bit to soon, i think the next couple mods will be coming in around my birthday in February.

Skeeterbop, very aggressive sound with very little $$ to boot on the mod. I like a lot. So much I may just make this my next mod. Thanks for introducing me to AAM. :tup:

Interesting, would the S-Tune Nismo pipe fit the bill?


.

That is what I was running before going FI

Since I haven't seen a pic of it, does the s-tune get rid of the y-pipe for a H or X pipe?

you have the basic setup as the stock but larger diameter. I do not have a pic of the y pipe just yet but here is the mid pipe with the resonators there. The short tails were something that was fabbed up when I bought the car but I have already sold them. http://www.the370z.com/members/kelly...1-100-1157.jpg

^Cool, it's my S-Tune's mid section, just needed clarification as a lot of people say Nismo CBE and they think there is only one the "H" pipe that comes on the Nismo model car. I can see from the pic they are the S-Tune mid section and tips (fabbed up). Not a bad idea and would save me a bundle of $$. But then for resale, I could probably get more with leaving it a stock S-Tune CBE system versus chopping off the tail piece. And I could always sell the shorties separate.

So for the $$ on AAM shorties would be the route I am going to go. If AAM shorties connected to the stock exhaust sound as loud as the video clips I have seen/heard on utube, then these will sound VERY aggressive with the NISMO S-Tune. Thanks for clarifying and posting up the pic. Skeeterbop I am jealous!!

ZForce, I'll have another video up shortly that I took from the exterior. It will give you a very good idea of what it sounds like at various speeds and under hard acceleration. This is with a stock exhaust except the AAM Short tails obviously.

A few pics of my Stillen front splitter. I used slightly larger hex head self drilling screws and two 5/16 bolts to make sure it doesn't come off. I may add a third dead center as well.

In for the video, thanks in advance for your contribution to the community.

Looks good, like it was meant to go with the lines and flow. It's not going anywhere with your mounting kit. :tup:

Been trying to get the video to upload all night. I'm going to go ahead and link it but it may not be available for a while since it is still uploading:
--edit--
I will update this post whenever youtube decides to correctly upload my video. been trying since about 430 this afternoon. I'll check to see if it is finished when i get up in the morning.
Video as promised:

So i have o pose this question to others. For my next round of mods I'm contemplating one of two completely different options. The first option is to order the Craft Square side mirrors and a rearview camera, thus allowing me to remove the rearview mirror which annoys me to no end. (it sits dead center of my vision when i look to the passenger side of the window.)

My second option I have been considering is a lightweight flywheel and clutch combo. I'm trying to go as light as possible, because the inability of the engine to drop rpms quickly has started to get on my nerves. I've been considering a lw flywheel for a while and figure if I'm going to pull things out I might as well replace the clutch at the same time.

I know the decision is ultimately up to me, but what would you guys do?

I would go with the clutch and flywheel combo for sure. That slow RPM drop annoys me too

Nice video of shorties. Is there any loss of power? With the the loss of back pressure are you feeling the but dyno to loose out on the low end of the power band? Of course after you get over the sound of the pipe. I like the sound towards the end, but for the most part it sounded tame, maybe due to the position of the camera. I am pretty much sold on them.

I am not up on the rpm drops you guys are referring to, please explain. Are you running with the synchro rev turned off? Or do your models come without them? I have heard lighter fly wheels make for hard starts off a the stop light and they sound like a cement mixer truck. Something I have always been on the fence with.

I can't tell that there is any loss in power. I think somebody dyno'd it and said it got them about a gain of 3hp. I wouldn't worry too much about the loss of back pressure since the stock cats and resonators are still in place. So far everyone that has hear my car has nothing but good things to say about it.

The rpm drop I'm referring to is when you are trying to shift from 1st to 2nd and you have to wait on the rpms to drop (feels like forever to me) for a smooth shift. Imo, the flywheel/clutch combo holds onto too much momentum. I'm willing to trade a bit more effort and higher revs to get started for this benefit. Once you are used to the lighter combo, it isn't any harder to drive than stock minus a little more effort.

Good to know, thanks, I am still down to get this pipe.

Thanks for the explanation. I am not sure on the trade off for the sound the car will make, I have heard once the lighter fly wheeel is installed and after a few months of driving they tire of the noise lighter fly wheels make and end up going with a heavier one to rid the noise. I did not pay much attention to first gear since it's a useless gear in the first place and I am out of it fast, sometimes I will just start out in second gear to just bypass first all together. But I know what you mean and I too have experinced the WAIT and what I do is roll the throttle, it's seems to me that there is a sweet spot on the rpm that with rolling it gets me thru the gear fast enough....imo. Be interested in how your set up works once you get them installed.

I was just using the 1-2 shift as an example, it is present in all shifts. I used to have an MR-2 that had a lw flywheel/clutch and I absolutely loved it. It helps with throttle response as well since the engine has to move less mass. It gives you a freer revving engine which allows for faster up and downshifts. It does have a bit of a trade off with increased chatter and more rpms needed to get off a standstill (less mass to keep the engine spinning) But it is something I'm willing to accept. For me the benefits outweigh the cons.

I had contemplated this mod on my Z33, thanks you have renewed my interest in this mod for the Z34. In for the results. :tup:

well, it's been a while since I had anything to add to my build thread, but I may have some new parts in the coming months. Once I know for sure I'll be updating again!

Keeping us in suspense, I see how it is.....

I thought it would be fun. Picked up Berk Hi flow cats and Stillen Headers for a great deal. Should have them paid for and in hand by the first.

Berk HFC's sound awesome. In for the combo and sound clip. What are you going to do with your shorties?

Honestly I'm not sure. I have yet to decide if i want to install them or not. From what I've found the performance is negligible and it's a lot of work. Considering the price I'm paying for everything, I may end up throwing them on just because.

Unless you're FI.. headers aren't worth the work to put them in... not for just sixish HP... lol... been telling you this! The hfc... yeah, that's a good call though. You know I'll help ... it'll be my fourth set installed in two months! >=)

what i was thinking was finding out how much it would cost to get a true dual mid-pipe with the x over to replace the factory mid pipes. That should liven it up a bit as well.

I heard the shorties are for sound only and there is a loss of back pressure and that is why there is no gains in performance. I was going to pull the trigger but holding off, seems no one has posted dyno on them.

Well, in a dramatic turn of events, I have decided to try to sell my Z. I love the car, but want something to tinker with. IMO the Z is a fun car to mod, but a bit expensive for tinkering with. So I'm looking to get a 240Z in it's place and start messing around with it. Hopefully in a few years I can get myself another 370Z. I would like to thank Darionlear for planting the seed to do this LOL.

I too will be turning away from the Z side. I'm going to the darkside and going to get a 2013 GT500 after my summer move.

Look forward to seeing that GT500 somwhere (even if just a pic on a forum somewhere.

I will post pictures. The question is what do I get in it?

Base $54200
SVTPP $3495 (need tech advise)
SVTTP $2995 (need tech advise)
Glass Roof $1999 (I like/don't need)
Cover $375 (won't use)
Recaros $1595 (not sold on these)
Electronic pack $2340 (must have)
Heated seats $295 (can't get w/ recaros)
Shaker Sub $1295 (don't want)

I'm gonna try to keep the car less than $60k.

Looks to me like the SVTPP is required for the SVTTP?

Yes you can get only the SVTPP , but you want the SVTTP you must get the SVTPP.

:gtfo2:.....jk lol.

So since I'm going to continue updating this thread with my 240Z progress, I figure I'll just list what I would like to do with it and cross items out as I go. The current prospect isn't running atm so that affects the list a little bit.

1. Get Car running
2. Replace all the bushings
3. replace springs/struts if needed (upgrade to coilovers if possible)
4. Rebello 2.7 engine (270hp crank)
5. 5 speed from a 280Z
6. LSD if I can find one
7. Fresh paint

One thing I would love to do, but is 99% likely not to happen is to get a 6 speed straight cut, dog engagement, sequential trans from Quiafe Engineering. I know how much the transmission would cost, and could probably save the money over the course of a year, but the fabrication needed to adapt it to the L series block and trans mounts would probably be a bit more than i could do. Doesn't hurt to dream big though. What is on that list though is things I definitely plan on doing. The first two will happen pretty quickly and the built engine could get bumped up the list depending on the state of the current engine.
Sure hope i don't find a rust bucket when i take a look at it later this week.

Did you buy it after all?
