Default new source for SS exhaust and piping

ok gang, i may have a new source for us here...a friend of mine to be exact...we will discuss his background later, what i want now is to see interest in 3" SS turbo back and SS intercooler piping TIG welded to use least ammount of couplers...

me and him will be making my set-up shortly and if we can manage to keep cost down, how many people would possibly be interested in future...

also what would be a reasonable price for a 3" turbo back, flange, 6" flex pipe, no cat, o2 bank, and not sure what ill be doing for a muffler yet, i was thinking flowmaster 3" but heard maybe not to do so...

also he will be making my FMIC piping, SS 2.25" hot, 2.5" cold, all mandrel bent and welded so you only use couplers on throttle body, end tanks, and compressor housing, fewer couplers, fewer problems, right?

everyone, please let me know what you think...i wont get ...promise

On a DSM a turbo back exhaust would be in the $850 for 3" SS. Here's the thing, there were only so many combinations people ran and the exhausts could be mass produced, thus cutting cost. Not so in the Miata world. It'd be too costly to develop an exhaust with enough options to suit the turbo Miata customer base and even then your market is limited to people who want to turbo a Miata and of those, people who don't already have a DP of some kind. You'd be better off making a 3" cat-back exhaust that comes with an optional adapter so people can bolt it to the factory cat and then making DPs as a separate project.

Also, couplers in an IC setup are not always bad thing, they allow for movement.

$850 wow
what is a good gauge as far as thikness? anyone?
i think i can do it for less than that i hope...
i will calculate a close estimate on this over the weekend, i should be able to come up with pretty close number...
what about IC piping??? anyone...would it be impossible to come up with something that will work for a lot of people??
thanks

unless you sold it with intercooler that would be tough too since everyone uses different intercoolers and different manifolds hang the turbo differently

What manifold do you plan to use and with what turbo?
All that comes into play. The IC piping would be nice but like m/n said, it depends on the IC, mani and turbo position.

no I don't see you having much sucess selling pre-made charge pipes, for the most part. You could make a greddy cross over tube with integrated BOV flange. Stripes already has the whole FMIC kit market.

you're also not going to do well with downpipes. too many different turbos and turbo locations.

you could have a lot of sucess making a cat-back exhausts, if you keep the cost down. enthuza had the market, but they've gotten very expensive. FM also has a large market share, but are also too expensive. I would like to see another turbo dual set up on the market, with a Y split, not a 1-in to 2-out muffler like enthuza's, but half the cost.

true that...most setup are similar though
i am starting to think that this is gonna be very difficult
i guess ill just take some photos of the set up and see if anyone can acomodate it to their set-up...
the exhaust im thinking should not be too difficult since there will be a 3" SS flex pipe included and pricing will obviously differ whether you want a cat or not...
this is not meant to be a mass production for a certain type of set-up, just car guys helping other car guys out in saving some money, i figured if i could mate a good welder with a miata enthusiast and for relatively cheap, others may benefit from it as well, the welder/bender () makes a little money on the side, and the miata guys now have another route to go with if they choose...so great quality at the cheapest possible cost is what im trying to accomplish...
the IC piping can be left longer and then you trim it down to where you need it, this will allow you some playing room (im starting to give up on the IC idea, any support:gay

Do your own research. I'm not going to develop YOUR entire business plan so YOU can make money off MY ideas. I've done enough.

I'll be in the market for a cheap (hopefully sub $350) cat-back exhaust before too long. But I'm a cheap-***, would be ok with 2.5" piping, and don't need SS.

+1 but maybe 2.5 or 2.25, 3" is a little big for me

Ben, I wasn't kidding when I said we're making exhausts over the winter. You can hold me to it.

PS: your welds will be UGLY

Ben, thought you may know it off the top of your head...
mazda/nissan- if i could figure out how to do it for $50 i would be due for some kind of humanitarian award or something...
atlanta93-a cat back should be easy...i dont know how soon ill have mine done, maybe a couple weeks or so...what kind of exit you want? a cat back should be way cheaper than 350 even shipped if you want 2.5" and galvenised steel, i guess it would boil down to what kind of muffler you want, other than that a cat back should be very inexpensive...
keep in mind guys, i am not a co. looking to get rich, im not making **** actually, the fab/welder guy will make some money, but i think thats more than fair, i wouldnt weld **** and bend pipes on my weekends for anyone unless i was ******* you...im in it to help people and to play with cars, which what i was hoping we all were here for...

I'd be down for a 3" cat back if it is a good price. So you could include a cat as well? And would there be a possibility of a 2.5" to 3" adapter for where it bolts to the downpipe?

Like I said, I am very interested, but I would have to wait a few weeks until I have a bit of $$. Doing this for a really good price would make you super cool , you want to be cool don't you?

Uh yeah if it is modeled after the stock system i see no problem for a DP back exhaust system in stainless 3 inch for the near 400$ range if a muffler was included magnaflow etc, from scot maybe 350 or so with out muffler depending on how much the hangers cost etc. As far as thickness post turbo thickness doesnt matter for ****, so long as it is standard exhaust thickness and stainless who cares right. FWIW i think the competitors are in the 500+ range for there baseline ****. Hell i could get 2.5 made out of regular steel here for 250 all day +40$ for a turbo flow muffler. But it wouldn't be mandrel bent, or stainless.

Mandrel bend is a must, I'd say

im still trying to figure everything out, as i suspected, the many different variations are bitin me in the ***...so here is the deal...
we will be making mine very soon...here is what im gonna run
3" all the way...
DP appx to where stock headers end
6" long 3" SS flex pipe
V bolt clamp and then a 3" SS pipe in location of stock pipe
i will use a flowmaster more than likely 3in3out after the axle
3" pipe (maybe something fancy and shiny) straight out

making a cat back should not run more than $150-$200 or less total, again depending on muffler...i would like for most people to just use a magnaflow or flowmaster to keep it simple and just have people tell me where they want it to exit, i have two NA's to model after, one with stock bumper, one with wizdom (big hole across the back)
will also be making one for a friend with an NB but wont have access to it regularly to model after (im gonna try to keep his stock exhaust though)
any help or input is appreciated now...id like to know before i get to carried away lol
again to all, i am not profiting at all, just helping connect the dots for everyone to save some money...only one getting any money are the pipe and flange suppliers and my friend thats doing all the mandrel bending and TIG welding for his time and wire used...thats it...this should be what we all waited for...
let me know everyone what you think...

speedf50-yes to all three or was it two...i can include CAT but it will be more...i think 3" cats are like 60-70 or so, so it would be that much more
as far as the adapter goes...we are getting touchy since we were gonna weld everything up prior to shipping, but it would be hard for me to figure out all the dimensions...ill get under the car and start thinking about that, if you have pic from current set up and some dimensions im sure we can work something out...that way you can just bolt it up...

any input please dont hold back

mazda/nissan-like i said before, i was hoping that i can do the cat back for way less than $350, and as far as sound goes, i dont wat to limit peoples chioces on mufflers, so they will all vary, but i can upload the sound of mine once complete, which is not anytime soon, i am in the process of gathering everything i need, still got a little ways to go...MS is next in line, i need to get in touch with that braineak... he rocks...
