Thought I would share a few sound clips. Basic details. 92 miata w/ a 408W.
Flowmaster delta series 50's.

Sorry, no revving. It was late and I didn't want to **** anyone in the neighborhood off.

Wow that is epic! On the other hand you just ruined my day. I thought I had good sound but damn mine is pathetic now!

What cam are you running? Where did you put the cut outs? What headers and are you 2 1/2 true duels or a Y pipe? Details I need details! Yours sounds way better than mine!


Well at least I have a new target for perfect sound in what you posted here for version 6 of my exhaust!

The Wretch

I'm running a Crane Performance Hydraulic Cam (can't remember the cam spec's right now). Some basics on the engine,

Forged Eagle 4340 crankshaft
Eagle forged H-beam connecting rods
Forged Wiseco pistons
Edlebrock Victor Jr. aluminum heads
Edlebrock upper & lower intake manifolds
MSD fuel pump
RJM standalone EFI wiring harness
A9L Ford computer
Griffin radiator

Exhaust is 2.5" true dual w/ an X pipe. Currently has no Cats, although, I'm planning on Magnaflow Cats in the near future (tired of smelling like fuel all the time). Cutouts are mounted about 2 feet after the x-pipe, about a foot before the rear axle. The headers are 351W shorty headers. Swapped from left to right for clearance and exit to the front and down. You can kind of see here. I'll try to find a better pick as I'm in the process of wrapping the headers and exhaust.



Here's a shot of the exhaust exiting

Oh dang you have a Ford build no wonder. Even with many $$$$ in cool parts my LS car would NEVER sound as good as your set up. It's just not in the genes.

So I aplaud you for an epic build and showing us how it's done!

The Wretch

Thanks for the compliments. My prior toy was a bolt on LS1 GTO. Pacesetter LT's, Catless Mid's, Flowmaster 40's. It sounded great...but...It's hard to beat the sound of a well build Ford. There's just something about their line of v8's that have a great exhaust note when done right.

By the way, your car sounds pretty damn good. It's always hard to chase a particular sound. A good set of ported 243 heads, a mild cam and LT Headers really help the LS1 shine and sound great. Unfortunately, I'm not sure I've ever seen LT's on a Miata build...

Soon to come - Name brand LT's, Kook's I think, engineered by V8Roadsters, available from Flyin Miata.

I can't wait to see that. I've been contemplating a custom built set for the 408W, as it could use the extra air flow, especially with the Victor Jr Intake. But, dropping 2K on a custom set makes me think about puking.

charchri4

You still might have to puke the new V8R headers are around $1100 shipped. I know a couple guys have ordered them but no results yet.

papz

V8R headers?? Have you heard anything about them yet?

FM posted a vid of the LS3 car that's running the LT's. It's a no cats car though.

Speaking of cut-out's, my QTP's have been flaky since week 1. It seems like the gears keep getting hung up.

While I'm not crazy about how they've held up, their tech support seems to stand behind their equipment. I spoke with them today and they will fix them... I just have to send them back to NJ.

Anyway, here they are installed (without the turn-downs):



And yes, the long tubes without cats sound amazing with the cut-out's wide open

charchri4

I keep asking IB for a like button and we need it again today!!! Very nice!

5.0MX5

DamnNice!!!! But we do need to talk about that Granny shifting. Old guy technique.....right foot to floor, tickle clucth....shift....hard... and fast! Still very nice and sounds almost as good as a Ford

GoKart

Yeah haha, my T56 is due for a rebuild. My syncros were not happy that night. It's all I could do to get a clean run

Here is a quick shot of QTP Electric Cutouts on the FM Exhaust system
They are controlled with wireless key fob
So now I know what a LS3 engine sounds like

They are hidden under back bumper , so you don't see them ��

mazdaspeedmiata

^^ wtf no sound clip !!??

tvp

I have to try to record sound while driving ...

mazdaspeedmiata

I like the way you dump out the back rather than leave it under the car. That's a great set up! For the file just put it up on youtube and put the link here. That's the way the forum pages work the best.

I'm doing a little tweaking with my exhaust too before the trip so we'll have to compare notes.

tvp

Yes the guys did a great job welding into the pipe just before the muffler,
All in stainless steel ,. I checked with QTP on we're to install so I did not effect engine tune , ox sensors, spark plugs etc, no X pipe .....just simple two valve install. The Key fob wireless works great ....don't have to drill and mount switch in car etc......I used the QTP Low Profile cutout kit 2.5 inch

The look on the faces of the cars you pull up beside are worth the price....lol

We leave on the 21st for Mitty .....should be fun !
