Richard, for the love of god sell your enthuza, it's useless. Meant for turbo cars and 16 year old ricers. It's just obnoxious. Surprised my HOA hasn't contacted me. Surprised you don't have Portland style riots in front of your house yet.

Buy something. Anything. I don't care if it's 50lbs. Hell, just keep your stock exhaust. I don't care. ANYTHING IS BETTER THAN YOUR ENTHUZA.

NB Speeder - Enthuza Car, Inc

Power Pulse Miata Muffler for 99-05 Miata - Racing Beat

Flyin' Miata : Exhaust : Normally aspirated : 1999-05 Flyin`Miata naturally aspirated single exhaust

ARTech Fabrication - Custom Fabricating

Just remember when you're shopping, to look for the NATURALLY ASPIRATED designation. Because when it relates to exhaust, you have a naturally aspirated car.

Do it for the children.

Is it 3 inches....if so I'll buy.

It's 2.5", mates to stock exhaust piping.

When there was a functioning cat on the car, it wasn't nearly as bad. And believe it or not, I DO have the NA version of this muffler.

My muffler: Enthuza NB XR Lightweight

Trubo version: Enthuza NB XR Lightweight Turbo

From the pictures, the trubo version has a bigger can. IDK why.

I had the trubo enthuza on my 01 for a bit and couldn't handle it, and that one has a much much bigger and quieter can. I can't even imagine running that pencil penis version. Must literally wake the dead

If I were you, I'd get the NB speeder for normal operation and keep the XR for when you want to go to the track and out-spec the spec guys! They should interchange.

And, order of loudness (from quiet to loud):

Turbocharged
Normally Aspirated
Supercharged

Supercharged + XR . . . man, that must be a spectacle!

it sounds worse than Laz did 1.6 N/A with the spoon replica muffler

Bah. You people :)

Stock muffler is going back on today. The XR isn't for daily driving anyway. Its only purpose in life is to allow me to hear the engine easily at high speed on track when the wind noise in the cabin is excessive.

You are about +200 from my weight with hardtop, just NB extra weight or what? Granted I've removed some stuff and have race seats but seems a little more porky than it should be.

I have the heaviest NB. I think it's listed at 2550.


Last weight I have was with hardtop, with ac, with trunk stuff, with stock seat, without me : 2604.

This weight is 2617.
-me = 2432
+ht = 2477
+AC= 2502

So I have stripped some weight, but it's still heavy.

slow fat car will still be slow :D

Just needs more torques.

O wait... :giggle:

if it's an 01 se it should be listed at 2350

2350 is probably a dry weight. No oil, coolant, battery, brake fluid, gas, or driver. All that really adds up.

Richard, I believe a lot of weights are posted with 1/4 tank or less, do some math and give us a real weight with wing, hardtop, no driver. I bet it's better than you'd think.

Curly has been complaining about how loud my car is with the Enthuza XR Lightweight. Which is, in fact, the non-turbo NA version of that muffler.

His dog, Jack, who loves me because I loves him, gets excited as I enter Curly's neighborhood. Without the Enthuza, Jack wouldn't know I'm on my way!

I mean, seriously, what could be the problem here :giggle:

Up to 156 miles now, did some VEAL on Skyline. Startup enrichments are much better now after yesterday's tweaking. Car is running well.

County. Jack gets excited when you enter my county.

Some shots of progress. MAF is still there because everything fits good. It's not a significant restriction. When I run out of more important things to do I'll get around to replacing it with something else.

The swaybar to oil cooler clearance is tight, about .5 inch, but manageable.

The reroute hose has enough give in it to still allow for top-down oil changes. Huzzah. It can be flexed up out of the way.

Once I get through the first 3 oil changes I'll hook up the oil cooler, and see if the IM brace will fit with 2x sandwich plates and an oversize filter. It's a bit of a pain to take on and off but I'd like see that significant IM mass which is out there getting vibrated on a reasonably long moment arm supported.

Looks tidy!

^This! I thought I was looking at Vlad's engine bay for a moment there. Nice work.

My oil cooler clearance is quite tight as well. Hopefully your radiator mounts are tight! ;)

I'm putting my sandwich plate assembly and intake manifold back on this weekend. I'll let you know how my clearances are.

always a pleasure to see clean bay

I think the maf is a restriction, though only a couple hp worth at your power level

Thanks guys. Maf replacement is on the list, just way under getting the car broken in and tuned.
