WU TANG MFers!!!! 3" exhaust installed
 
3" exhausts rock your face off.

cjernigan 10-20-2007 06:35 PM

Well, guess the next most important thing to ask. Is it quiet enough for you?

Braineack 10-20-2007 06:41 PM

no. but it's liveable. I trust with a resonator and a cat it'd be fine. I'm also used to it not making any noise at all. Cruise is nothing, up hills could be a tad quiter, but the growl it makes when WOT is toally badass.

sad thing is i was peaking something like 17psi with the same tune (was topping out at 13.8psi before) and i blew a coupler and it killed it, so technically im N/A for a few days (2" 90*) which totally sucks balls. what can ya do?! :dunno:

Ben 10-20-2007 06:42 PM

duct tape

Braineack 10-20-2007 06:46 PM

tried it. failed on the drive home. problem is the coupler acutally ripped, i guess i tightened the t-clamp too much and it cut into it.

yeah it does. i've been 3" for about 2 mos and love it. since then i've started ignoring all those spam emails in my inbox about bigger penis.

y8s 10-20-2007 06:58 PM

pics or :gtfo:

Tesseracter 10-20-2007 11:51 PM

+1 pics. how does one "add" a resonator after the exhaust is installed, you have a straight pipe for the cat and another straight pipe for the resonator?

neogenesis2004 10-21-2007 12:15 AM

There is no resonator, drop off car at exhaust shop, they take their magic wand to it, voila, you have a res welded in.

cjernigan 10-21-2007 12:17 AM

Werd. Local guys welds anything you want in for $20 and 20 minutes, cash only.

Kelly 10-21-2007 05:03 AM

I'm proud of you Brain.

Pitlab77 10-21-2007 11:10 AM

worthless with out photos

Arkmage 10-21-2007 12:02 PM

My 6" tip makes twice as much power as your 3" exhaust.

*edit* because it's bigger *edit*

Braineack 10-21-2007 12:52 PM

I got pics I forgot to download them. Will get soon. Gotta show you my failed coupler too.

looks good, did you do it yourself? shop? friend? Mine sits a bit lower than yours, one of these days im gonna rework it to not sit as low.

Arkmage 10-21-2007 03:42 PM

got any scrap pieces left over that I can use between my turbo inlet and air filter? Like maybe a 45* or a 90*?

cjernigan 10-21-2007 03:44 PM

Pretty sure it's an Enthuza built piece, he just had him use the Magnaflow muffler instead.

levnubhin 10-21-2007 04:36 PM

Sound clip?

looks nice.

noah, what scrap you need?

Savington 10-21-2007 06:15 PM

Why did you go with the Magnaflow over the Silverline? My Silverline is not loud at all, mabye as loud as a stock STI.

once i fix the coupler.

shuiend 10-21-2007 07:50 PM

I am sorry I broke your coupler. I blame it on u leaving early and not helping me finish my turbo. But the gods have humor and I am driving around shooting air out my turbo jsut like you.

Braineack 10-21-2007 07:57 PM

nice! glad to here to got it finished up!!!


here's the said coupler:

and here's my favorite part, the 2.75" to 3" test pipe to match my DP.

Pitlab77 10-21-2007 08:12 PM

very nice

magnamx-5 10-21-2007 08:16 PM

Is the coupler a angled coupler? if not then a peice of radiator hose should get you back on the raod. +1 on the sound clips beigna major requirement. ;)

Braineack 10-21-2007 08:21 PM

no it's a 90*, otherwise it would be fixed already. I'm running it as is untill the replacement arrives, no biggie. My drive isn't far to work and I'm running a map sensor so the biggest worry is running unfilter air, which i dont really care about.

miatamania 10-21-2007 08:26 PM

Really like the test pipe...very slick.

kotomile 10-21-2007 10:00 PM

I had Jason weld up the same thing for me, but in a 2.5"-3" transition instead. So our exhausts are nearly identical but I didn't specify the magnaflow can.

watch laying into the throttle, you can overspin the turbo since it will never see high enough to open the wastegate, better off if you're gonna drive it open the wastegate somehow

y8s 10-21-2007 10:12 PM

SCOTTTT what size is your bum coupler? I have a 2.5" 90.

Braineack 10-21-2007 10:22 PM

it's 2" :(

my wire coating didn't melt matt. so ha!

N/A is so redicously unbareable...blah.

haha, good. must be good wire.

rappadan 10-24-2007 06:03 PM

how did the transition into boost feel. Was it ridiculously faster? After upgraded from 2.25 with glass pack and muffler to 2.5 and only 2 small resonators it spooled soo much faster!

jwarriner 10-24-2007 06:11 PM

I hope your muffler doesn't make your tires HOT.

yes, much faster datalogs tomorrow morning pending weather. rain doesn't make it easy.

haha yeah i'm thinking about installing head shields.

Braineack 10-24-2007 09:12 PM

the coupler:

https://www.miataturbo.net/~web1_bra...exhaust006.jpg

https://www.miataturbo.net/~web1_bra...exhaust007.jpg


my theory is:

since i cut it so short, it had no room to wiggle & flex as needed. that and i campled down my t-clamps very tight (extermely) and dug into the silicone enough that when the engine torqued up it started eatting into it. Combined with the ultra power of my 3" exhaust, it was just a diasater waiting to happen ;)

Zabac 10-25-2007 09:36 AM

i like ultra power :bigtu:
what kind of coupler is that anyway? it looks pretty meaty, i mean i know its a 2" silicone, but it looks kinda weired...where did you get that one

Braineack 10-25-2007 10:13 AM

just a typical 4-ply silicone coupler. I believe it's actually an OBX branded one.

the rain is preventing me from getting a good log, but with my MBC backed off a bit, i was still logging 16psi....talk about the last exhaust being a restriction.

cueball1 10-25-2007 12:52 PM

Gunna Dyno that biatch to give us real numbers between what you were using last time and what you have now? Love to know everything you changed between then and now and see what the gains are!

+1 for Sound clip!

nice sig. also nice wheelspin at redline.

Braineack 10-28-2007 07:28 PM

finally got the old pics i took during the install to compare to the old exhaust:

Exhaust systems are beautiful works of art. I think I am going to run mine on top of my car instead next time.

I wish I lived closer because I have this incredible urge to clean your wheels. No inuendo intended.

How much space is there for wiggle room with a 3"

TurboTim 10-29-2007 08:42 AM

Is that stainless? The weld areas (on the test pipe particularily) look spraypainted or something.

Also, is the tip touching the bumper? Looks a little offset, might be the angle of the camera?

Braineack 10-29-2007 09:23 AM

no aluminumized (im cheap remember). the exhaust is perfectly centered, in the pic I only have the muffler hanging there.

there's about .5" of wiggle room around the diff's stub shaft flange and enough room around the ppf.

Zabac 10-29-2007 10:31 AM

looks good, the borla looks way to complex, it needs a diet!
is the new exhaust any louder? but i like the new one much better
