Exhaust

[deerock]

will be doing catback exhaust next, and wanted to know what some people think of the few exhausts that i like. if you have any better recommendations feel free to post it up. im leaning torwards the borla right now. it is the dual exhaust style btw.

there is a poll on this.

[wildfire0310]

I have a borla single pipe on my car right now and I love it. it is a great exhaust for an N/a. Loud enough to give character to the car but quiet enough to not piss off the girlfriend/wife.

[deerock]

nice nice. thats what im aiming for. i do like reviews too, helps me pick out things :D

idk if anyone has seen, or knows lee ann with the burgandy miata with a hard top, but she has the borla dual exhaust and i love it.

[Roadster]

^ Having ridden in her car, stay the hell away from the one she has. It gave me a splitting headache within 10 minutes. Worst droning thing I've ever ridden in.

[Roadster]

And as far as testimonials go, I had a 2.25 in. catback made up for my white Miata at a local shop in Covington that does custom work on street rods/race cars.. Flowmaster 40. Sounded a lot like Acro's car but not quite so crackly. Had a nice snarl to it but it wasn't deafening. The tone of a chambered exhaust is a lot more raspy than the kind of mellow drone that you get with straight-through mufflers. :)

[deerock]

lol its because she has a hardtop lol. and hers i think is full straight pipe to the muffler. mines gonna have a cat, resonator (extra pipe w/out one for track.) then muffler. so i should be avoiding the terrible drone.

but im also considering having my buddy custom fab me one at his exhaust shop. so thats 2-300 bucks lol

[metalman]

My .02 opinion..."duals" on a Miata really arent as there is only one midpipe...and when vapor is visible it comes only from one side...looking kinda ghey. If it was me I'd go for a good single exhaust setup of your choice. ;)

[deerock]

lol i like the dual better :P

plus every miata i see has the single tip. im going to be different :D

but i do think that the visible vapor from one tip is gonna be HILARIOUS! :lol:

Actually it was with the top off and at relatively high speeds. It's that bad. Lol.

And duals ftl. :P

[RotorNutFD3S]

FWIW, I had FM duals on mine, and I did get the exhaust vapors out of one side, but only when it was cold outside. Other than that, both sides flowed about even, especially at full throttle. The Enthuza I have splits them evenly, so it'll look like true duals when cold.
And I think duals make for a good looking Miata.

[metalman]

lol i like the dual better :P




Well at least I participated in your thread poll. :P

I'd say get a St. MArtY center exit exhaust....BUT...there is only one of those in existence. :lol:

[deerock]

yeah, and only three did

hahahahahahaa and YOU have it! :lol:

[Jack-MX5ATLanta.com]

I'ld talk to Enthuza on here in his forum about your options with him. He makes Miata specific exhausts with dyno proven gains at very reasonable prices. He also uses Borla mufflers and has quite a few different routes you can go. I have his 2.25 resonated borla and it has a really rumbly mellow low end and sounds stockish high end. Making it fun and easy on the ears when cruising at 75mph but still noticeable around town and at autocross.

But like I said, get in touch with Enthuza, he's better priced than a custom exhaust and has alot of Miata experience.

Unless you changed what you had, yo u have a BOSAL/Brospeed exhaust. IIRC the Borla is rather loud. ANSA and Roadstersport make rather nice exhausts too. I'd probably recommend the ANSA for the sound and the style of the tip is nice... i'm not one for thick-walled tips like the RB and the Bosal. Speaking of RB, they have a twin-tip muffler that looks pretty BA. Try doing a search of different exhausts on youtube... you'd be surprised what you'll find on there :)

Here is the twin-tip RB...

My duals very obviously flowed from both sides. some 1-in to 2-out mufflers however don't divide the flow well at low exhaust volume and end up creating a venturi that sucks through one end and blows out the other. However, with most of these mufflers, when throttle is applied and exhaust volume increases, both pipes end up flowing outward.

I like my duals because they look baller and sound awesome, so I don't mind the couple extra pounds they add. However if my motives were purely performance oriented, I'd get a single exit exhaust.

Whatever you do, give Jason @ Enthuza a chance. He can make something to suit your needs and he's local.

[Jack-MX5ATLanta.com]

Yes, pm Jason!

hmm i really dont like the look of the twin tip..kinda weird lol

i did do the research on youtube, and found that i liked the borla duals the best, as i couldnt find a good RB dual clip, plus like you said mike, im not fond of the thick walled tips lol

what exhaust do you have Ben91? and i will deff pm jason on here and see what he says.

[ben91]

my duals were custom. the exhaust that's on the car now is a 3" single from enthuza I was using until Jason had time to build me a baller dual 3".

[MeFryRice]

I personally prefer the look of a single compared to the dual.

[jesseealexander]

single FTW. the nicest sounding muffler ive ever heard on a miata was matt's power pulse. it was perfect. nice and deep, loud but not offensive and NO droning.

[Roadster]

My old car with the Flowmaster 40, gutted cat, and header...

[deerock]

word^^ i remember that car like it was yesterday. but i think ima go woth the RB duals just cause it makes more power, and looks hella tight.

[BFH miata]

did someone say RB duals?

Hey D-man.. thank you for not wanting to go with one of those gaysatic looking exhausts that the CR crew makes out to be God. :lol:

[Flash13783]

I'd go with enthuza too i'm working with him right now and he's awesome. i'm trying to get mine to sound like the s2k with megan exhaust. I love the loudness and sound

[Sawyer]

I love my Enthuza... :P

[deerock]

http://www.bfhgarage.com/BFH-Images/miata/bfh1-mitty-2007.jpg

how do you like that set up?

does it sound good and still make good power? cause i really like it, but ive been looking at the single tip recently..

[simontibbett]

I got a Supertrapp, owns all, the end. Make it loud, make it quiet, make more low end torque, make high end torque, all within minutes lol.

[deerock]

well im now stumped between the Roadstersport 3 exhaust or the RB single tip exhaust.... anyone have the RS3, im reading a few reviews on CR.net and it seems to be worth it.

any opinions?

[jesseealexander]

get a supertrapp ***********

[metalman]

The Roadstersport (also known as 'Chinasport' :D) is ehh okay, I had one.
I think for quality of build and all the RB is better. Its a little mellower sound too.
If you want a cheaper alternative I actually like the OBX better then the Chinasport.
If I was going to get a new exhaust though I think I'd just check out what options Jason
has and go with one of those. No shipping required either. ;)

[MeFryRice]

Hey D-man.. thank you for not wanting to go with one of those gaysatic looking exhausts that the CR crew makes out to be God. :lol:

I too wanted to get an RSR exhaust but since I'm going a different route now, I have a different idea in mind. :)

[ben91]

If that involves a turbo (which it should), then we should work something out between me, you, and Jason on this 2 month used Enthuza stainless 3" I have in the garage.

[deerock]

i think im just going to do the RB exhaust, most of my experience is with RB anyways, but enthuza is still in my options, as im not ordering until next week.

[Jack-MX5ATLanta.com]

Depends if you want classy Borla sound or raspy racingbeat.

[FE3tMX5]

Go buy a 110v HF wire feed welder for $200 and build your own. I've got a used hooker raptor turbo style muffler and a 2-1/4" straight pipe exhaust from my NB race car I will sell you for $20 to get you started. You just have to come pick it up. When you want to try something else out, just cut out the old muff and add a new one in its place.

I built the one below for my sister from a MSM rear section, just welded up the two pipe sections as a jig and cutout the stock muffler.

racing beat exhaust is NOT raspy...

[metalman]

racing beat exhaust is NOT raspy...

True.

[Jack-MX5ATLanta.com]

Really? The clips I've seen on youtube sounded pretty raspy. I apologise if mistaken.

[jesseealexander]

nah. alot of youtube clips are recorded with ****ty microphones that cant handle the volume. they actually sound really mellow and warm, but still loud and raw enough to sound sorta mean.

[ben91]

My RB is definately not raspy, but I also have turbo so...

[metalman]

If you have heard my black car you have heard an RB. ;)
Its possible you never noticed though.

[Roadster]

You don't usually make a big show when leaving meets, so I for one can't recall ever hearing it. :p

I'm getting another Flowmaster 40 rigged up on mine next week. I loooove the rasp. But this time around it's going to look like this...

[simontibbett]

Damn that's going to look hot ^^^^^^

[deerock]

that does look pretty dang cute. i think ima go with the race connecting pipe and the RB muffler.

[manmiata]

What do you guys think of Megan racing or the magnaflow? What are the REAL power gains from any of them??

[Reverend Greg]

Had the RB and It droned like no tomorrow,I removed the resonated tip and it helped some.Custom fabbed a 2.5" system with a Trush Glasspack and 90* turn out out the drivers side,a little too loud for some but nice note and no drone.a well tuned engine sounds better than a one that needs to have the plugs changed and the timing is less than

Go Enthuza. Local business, high quality, great customer service and good sounding exhausts.

[GVfanatic]

Duals from Enthusa is the way to go. i prefer the Ansa silverline duals Jason built. sexy *** tone

[fun02se]

I started with a Borla Touring, then added a Flyin' Miata 2 1/2" mid, then added a FFS, next a 4x2x1 header.
Rresults in order: great, medium loud, loud, real loud!
I just built a catless with 24" 2 1/2" resonator! Back to great sounding now!!

[manmiata]

whats the price tag like?? Any real horse power gains??

[cappina6c]

I agree, single looks much better than dual IMO. As for the exhaust, im pretty sure you can go to muffler shop to get a custom one built for cheap. I havent done it but my friend did and he loves the custom 2.5 catback.

[eyeballs]

+1 for enthuza. I believe thats whats on mine and I'd say it sounds perfect for a miata. Very sporty tone, not raspy. Loud enough to easily hear with a helmet but not nearly as loud as a race exhaust. And looks fantastic, single tip.
