thats sweet...is that yours? nice
a dual should not be very hard...but more expensive again...more parts more money...:nono:
that one goes under the axle, no? i will go over...
that is nice and shiny...not my style...and looks so heavy
wouldnt you rather have one muffler with dual outlet...it is just for looksanyway right?
ill draw some designs up over the weekend...

we should be able to build exhausts for evey taste, cheap for the cheap, and not so cheap for the quality shiny stuff...

2.25" Enthuza, no resonator, OEM cat: 29lb 12oz.
My 3", no resonator, metal core cat: 24lb 0oz.
I used the 5x8x18 magnaflow muffler, kinda large.
The exhaust I just did for Paul with metal core cat, no muffler, a small resonator, and driver's side exit was 18lbs somewhere.

Goin' over the axle huh...I wanna see it.

I have a OEM '95 exhaust that I can get the hanger and cat flange location from...I have been considering trying to sell my version of the 3" catback but I don't think many will want to pay what I'd want to charge. Plus to ship it I'd need to put a joint somewhere in the middle which adds cost.

Do a 3" stainless catback for <$300 and I'd probably buy it for the raw material ;)

My last exhaust on a 95 was ~$950 installed, but that included a metal core cat, Burns smooth/long transition from 2.5 to 3", all new hangers, and redoing/reorienting a portion of the BEGI divorced wastegate downpipe. They put the O2 bung facing down?!?!?! Plus it's 2.5", not 2.75", and the 2.5" section was a form of stainless that rusts. :inout:

What was it exactly, out of curiousity.

No that's not mine; it's the one I told you to copy and sell for less.
Mine has a 1-in 2-out type muffler.

GFL going over the axle.

Zabac 09-12-2007 02:21 PM

Turbo Tim-i did a bit more research...most place are selling 2.25-2.5 mid pipes for in the 400 neighborhood, but most also use polished SS mufflers...i can build an exhaust for less than that for sure even if the person wanted to use a polished muffler...in other words, what ever the person wants to pay for is what ill make for them...

Ben-i could make that, no problem, but two mufflers means twice the money...it wont be as cheap as the other exhaust, but im sure i can make it cheap than what they are being sold for now and still offer peopel the chioce between cat test pipe or just straight pipe...but why would you want to have two mufflers...it would make more sense to have a one in two out muffler...less weight...

What was what? I don't know the exact alloy metal BEGI used for that diameter section if that's what you mean. If you want to know the exact diameter, it was like 2.511 with the surface rust.

EDIT: I should have said "it was a form of stainless that rusts and is magnetic". Strong magnetic too, like I hung my drop lite from it.

I know mild steel rusts and is magnetic. But BEGI wouldn't sell a stainless downpipe with mild steel sections. :squint: The 1.5" wastegate tube and the 2.25" upper main downpipe section was stainless and looked brand new (the kit had few miles on it according to the owner).

But they did put that damn O2 sensor bung at the bottom of the pipe...steph?

You know they do that all the damn time. At first, I thought it was by accident, but because they keep doing it, I'm starting to think it's by design. Perhaps they're not expecting people to run WB sensors full time, so they put the bung at the bottom side to make it easier to stuff a sensor in the bung at the dyno?

That is my only conclusion that is logical. Really, if I were making a downpipe/getting one made, I'd probably have 2 wb bungs installed; one up top for my sensor, and a second bung with cap at the bottom for the dyno's sensor.

cjernigan 09-12-2007 03:15 PM

Yeah i thought you might be referring to a particular alloy of tubing. Weird stuff.

Zabac 09-14-2007 10:19 PM

dont give up hope yet, lots of R&R this weekend and Magnaflow polished SS mufflers will be the norm in the first few sets...should be coming with first example of 3" cat back...it will be a round mufler mounted diagonaly under car and evit stock location...i will make it in any variation/spec that anyone wants...i will use other mufflers upon demand...i will be designing this one first though...let me know

UrbanSoot 09-15-2007 02:02 AM

make me a very quiet 3" turbo exhaust without tip (i have a very cool one laying around) and ill buy it!

thanks for your support, im not sure how quiet it will be, but once i have one made i will upload sound clips...i do have a muffler that should be very quiet though...ill see...pm me with your info (what turbo etc...stock exit muffler?)
thanks

Zabac 09-19-2007 02:19 PM

its getting hotter...
 
heads up...my SS flanges arrived today, should start build of first exhaust this weekend...
i've been very buys trying to lower the cost on eveything, any help is appreciated
if anyone can point me in the rigth direction as far as v-band clamps with flanges are sold (stainless) they are pretty expensive, lowest i found is about 27-28 for each set, i'd like to use two for each exhaust but may switch over to just one...will make harder to ship and remove/install
if anyone knows how to get them dirt cheap, please let me know...
everything else is in line so far...:bigtu: good deals on magnaflow mufflers in all sizes and styles pretty much...
the first one that wants a stock looking exhaust will get a huge deal...i picked up a new magnaflow 3in3out stainless (not polished) oem location style (hope this make sense) for only $31 on ebay (new from individual), so heads up all...we should start production very soon
thanks for everyones support

cjernigan 09-19-2007 02:31 PM

Only place i know with cheap vbands sells them with mild flanges and stainless clamps, they're $30 I think.
You can buy in bulk from this company and they give a discount to homemadeturbo.net members http://store.racing-solutions.org/

Zabac 09-19-2007 03:05 PM

yeah i see they are with mild flanges though and they are 35 ea...
they are selling SS flanges for 20 ea...i found the SS clamp with mild flanges for less than 28 shipped, i was looking for cheaper, or for ss flanges with same price...but i may have to go with mild...i hope these come down in price like everything else...

cjernigan 09-19-2007 05:43 PM

Mild flanges wouldn't be all that bad, they would tig well to stainless pipes with the right rod.
If you contact them they might give you a better price if you decided to do some sort of bulk order.

Zabac 09-19-2007 06:24 PM

yeah i know...i talked to every ebay seller...whats funny to me, the range in prices is ridiculous, anywhere from 40 shipped to 70 shipped for the same shit
the mild ones on the other hand i found from 28ea to 40 ea...makes no sense, i think they will get cheap within a few months, the market is demanding them...i may just order the bands and get someone to cnc my own flanges...but then again thats a lot of work for me with very little time...fuck it, i think ill just use one for after the DP before the flex pipe and call it a day...you want fancy clamps it'll be more, lol thats as simple as i can figure it...take it or leave it, you know...
oh, hell, midl steel it is damn it...i made up my mind...
also, do most DP's end where stock header would end...im not gona run a cat, so it will be easy to make "DP back" and then make DP's to end at stock header end...simple enough
i am still debating the routing around the axle area...we'll see this weekend how things go, ill let ya'll know

Zabac 09-21-2007 05:58 PM

ok loosers, its friday, i better not see any new posts from now till monday morning, lol, i know that aint gonna happen, ill be here sat morning asking for help, putting 99 head on 96 block in my friends 92, yeah thats what i said, lol
after that, its onto exhaust development...wish me luck
ill let ya'll know how it went

yeah the dp ends where the stock header ends. Well most do, some require "minor fabrication" :bigtu:

Zabac 09-24-2007 11:12 AM

i realize making the DP for myself will be very easy, but its almost impossible to make one for other DIY'ers...its gonna suck, i may just stick to DP backs...unless i made pabricatable DP's to fit appx. and then you make it fot to your turbo and the back of DP by cutting and welding it yourself, does anyone understand me? i dont understand me...i have voices in my head...they tell it will work, i wish you guys could hear them too :)

Zabac 09-28-2007 03:29 PM

ok, some more stuff arrived, i may have something done tomorrow...wish me luck, i have arranged a time with my welder/bender (lol) tomorrow afternoon to test bend some mild pipes for fittment and clearace...im so excite
should i snap pics or no...would anyone even care to see them?
