oh my phone captures the hiss and the pops and everything. i just feel its not as perfect as it is in real life. :tiphat:

my hiss gets mistaken for a BOV everyday lol

Use exhaust wrap on the test pipes and y-pipe. It will deepen the exhaust, remove some drone inside, lessen the hiss from the test pipes and reduce the rasp drastically.

I might do a wrap, but seeing as I am still debating even keeping the entire assembly, such a measure might be an unnecessary expense. Worth a try, though.

Sounds good to me. Love when it trumpets. But it definitely gets old on the street.

i disagree lol i've had my set up for a year now and about 10k miles and its super loud. hasn't bothered me one bit and i daily drive mine. i'm still searching on how i can make it louder.

Megaphones. :icon17:

open test pipes :stirthepot:

open gangnam style :bowrofl:

dammit haha :roflpuke2: well played.

Open test pipes with megaphones :stirthepot: :stirthepot: :stirthepot:

Repped :rofl2:

haha sorry i dont drive a lame BMW M5 where the speakers make exhaust sounds too lol :stirthepot:i had to throw this in there :bowrofl:

but i am for real considering and looking into running open test pipes

Well I was talking about attaching actual megaphones to the test pipes, but of course I was only joking :p

haha such a fool :roflpuke2:

The best and loudest option is probably a long tube header that exits out the sides, before the rear axle. This would probably provide some decent backpressure for an NA and also give you a LOT of noise. You'd also have to consider finding some way to prevent the header temperatures from cooking your doors (and potentially any passenger's/driver's feet and legs).

EDIT:
You might even get pretty respectable afterfire! With barely any room to detonate dumped fuel before the exhaust exit, you'll get some nice flames (and likely cook your door panel, melt the paint, and possibly warp your pinch welds, unless you plate the area with some steel). Another option is to change the stock fuel cut/air cut to an ignition cut. Better for the motor if you're ever bouncing off the limiter, and even more opportunity for fire and you'll also be running a 2 step!

i like this idea. the heat issue was one of my concerns with running open test pipes. i can feel heat coming up from that section even now with my full exhaust.

You could definitely wrap some of the portion, and also ceramic coat (but probably not both). A nice, thick ceramic coat should also help with exhaust scavenging and lower some of the potential that the exhaust gases will cook anything near them.

well it'll be up on the rack soon since i will be doing the end of the year cleaning before it goes to sleep for winter. maybe i'll do some research and see what i can do.

Some custom fabrication is definitely in the works. This is pretty much a race car setup, so you're gonna wanna find a good shop.

Something to consider is that you can have the pipe visible by running it along the length of the sideskirt (you'll probably want to remove the sideskirt to replace that whole length with pipe, since you'll barely clear the ground otherwise), or by going until the point where the stock y pipe ends and where the stock midpipe begins, then bending out towards the front of the rear axle. This would eliminate some issues with the paint melting, but then you're introducing more bends into the exhaust, which is never a good thing.

This would probably look a lot like the AC/Shelby Cobra.

You can also have the long tubes end right behind the front axle, which might be easier to manage than running a length of tubing that far back into the car, where it was designed to go straight through the middle until you get to the rear exit. Less heat transfers to the car, and you'll not have much exposed pipe, although it still brings the issue of cooking whatever is along that path, like brake lines, clutch lines, other fluid lines, etc.

haha youre making this sound like more work and heartache than fun. worst case i'll just cut the fckin mufflers off and put 2.5" pipes in there place and literally have straight pipes lol theres more noise, same heat level, and not alot of R&D time lol

That work and heartache would transform into beautiful, ear-shattering, pants-soiling, panty-dropping, steez-staining, soot-leaving, fire-making, power-producing noise.

Although it's all hard parking unless you track it.

Plus you have the opportunity to produce a unique exhaust which may eventually end up being an "off-the-shelf" mod, although it's quite a lot of work to make the mod work.

If you give up on that, though, running long tubes with the developing AAM exhaust for the short tails pretty much gives you straight 2.5" piping with almost no resonation.

mine is pretty much brutally loud as is now. even though it has its tame side at idle but you smack that gas with the windows down and your in the lane against the jersey barrier it makes your ears ring no joke.

i actually have a secret plan forming right now for a winter project :stirthepot::stirthepot::stirthepot::stirthepot:

I am excite for this secret plan of yours. :excited:

eh its not really a secret per say lol my buddies own a shop and they do custom exhaust work. i was thinkin over the winter taking mine off and use it as a template of sorts and work something louder up lol :stirthepot:

maybe more powah too lol

you must build it and show many pictures. MANY pictures.

Screw the pictures, it's all about videos and in person demos with exhausts. I expect both from you sir :tiphat:

Wow this thread went far!

Here's a few vids of folks over here in paradise no exhaust restrictions!

Check out my videos I got a sh!tload of them!

Plus when you compare our cars to big V8s it's not that loud at all!

Figure I'll toss up some videos of mine, I still don't have a good video of a long fly by though :mad:

well for one i have to decide on if i am gonna do this and winter still is 1 to 2 months away depending on the weather. last year my Z went away last week of november before i left for hawaii since it wasnt very cold nor snowing lol

and if i do attempt this yes there will be pics and if i complete something there will be video. no promises this is just an idea i have been thinking about.

It's not a bad idea...you'll need some unnesscary bends to help with back pressure and cone style tip!

Which may be hard to squeeze underneath the Z...easiest is LTH into a y-pipe to a cone off to the side!

perhaps you should break the mold and join the motor headers into a single 3 or 3.5 inch section and have it go directly to the rear and then split, or do a single pipe exiting into however many tips you want, a la Corvette or 458 Italia or Cooper S or whatever. does create a want for backpressure though.

sounds good in theroy but 3" is too big for N/A set-ups. 2.5" holds good back pressure. im thinking still running true duals but just eliminated my muffalers for starters.

If there's an exhaust that is truly true dual, i.e. each bank has its own exhaust and the pipes never join, maybe that will do something. I'm just throwing ideas out here now.

my current exhaust is true duals. left header straight to the tip and right header straight to its own tip. no crosses or meeting points.

you guys have some balls.

i custom welded resonators to my short tails after a few days.

way too loud for my taste

It's a copy of the Amuse Exhaust, but true dual. I don't remember the other options for the Amuse exhaust, but it's $$$$$

I think our balls have vibrated right off.

That's not true dual those meet at the fronts. Fast intentions has one of the only true dual systems.

Haha vibrated, balls, off. Hmm re word that and it makes sense really

u probably wouldn't want this. companies dont jsut make H and X pipes in a system for the hell of it. H-pipes equalize back pressure and X pipes help you take advantage of the scavanging effect created by different banks of cylinders firing. i.e. increased power. loss of performance and awful sound would be your only differences with a straight dual system that never touches.

that equalizing of presures and tones really does make for a great sound. thats why so many people love the sound of a single side on these cars
