My comment towards the Magnaflow cat and y-pipe is to say that the last quality alternative to the OEM y-pipe is now gone. If you ever want to bring the truck back to stock, the design of this downpipe makes that impossible--essentially installation of the kit is non-reversible. Or more accurately, the cost of reversal is the purchase of an OEM y-pipe ($1493 according to Norwalk Toyota website), assuming it will still be available at some point down the road when/if you decide to un-install the kit. Yes, you can rely on your local exhaust shop or hot-rod shop, but that isn't a great option for some folks.

Bosal (and now Magnaflow) is not an option, been there, done that, wouldn't touch with a 10-foot pole.

Agreed. I'll post up what I'm considered after I talk with a few folks.
 
I’m guessing OTRAMM & other exhausts are cat-back designed.

Not that, if they did have a y-pipe, it would be compatible with this turbo set up.

Is Joey’s y-pipe just missing a 90-degree turn at the bottom, instead of the flexy bendy portion, all that is making this actually bolt-on?

It just adds the expense of muffler shops & a tow truck to get it there too.
 
I get keeping it so you can go back to stock, but I know I’ll never do that. I saved every part off of my Tacoma and I almost dumped it all in the trash a few weeks ago. I’m never going back.

I’m already thinking LS is the only option for my 94. I do want to try the turbo on my 97. I already figured there would be mods to make it all fit.

In my mind I wanted to keep the factory cats but cut the Y-pipe at just before the split. A straight cut would allow the addition of a flange but if needed, a sleeve could be welded between both pieces to bring it back to stock.

BUT...since this was going to be a CARB certified offering, the need to reverse it would/should be moot since, as ThomasMore66 mentioned, who would want to undo the turbo? Now initially, before I was heading the CARB direction, I was trying to build it as bolt-on/bolt-off for smog purposes. That changed.

So consider the downpipe/exhaust portion as UNDECIDED for the time being.

I know a lot of us think we'll own our trucks forever and some of us probably will, but I've had to pull all the aftermarket parts off a vehicle that got in an accident and was totalled by insurance. Some of us are also serial "shoppers" :hillbilly: and might swap all the goodies over to a better condition truck, or remove to sell, etc. Just my experience and observations.
 
I just got mine in 1993. I think I'll hold off for a while to see if I like the truck enough to keep it for a while. :rimshot:
 
one option might be to do a radial cut around the front cat where it welds onto the Y pipe. The Y pipe actually slides into the front cat. The Y pipe diameter at that point is 2.5". I know this as I did that exact cut and slid a magnaflow cat over the front Y.

Doing this would place a clamp where the down pipe or the stock Y pipe slides into the front cat.
 
These sound like singular, subjective problems; not something Joey needs to address for a mass audience.

Just my .00000000001 cents.

I dont disagree but I need to consider all the options. Since this is a production product it needs to suit the masses. If this was a one-off it wouldn't matter.

THAT is actually one of the solutions I'm considering.
 
That could be a better solution--one consideration is that if anyone is currently running a Bosal y-pipe, it is a smaller diameter pipe than stock and uses a bottle style cat of different dimensions (and probably slightly different location) than stock. Don't know how many of your would-be buyers might be running a bosal y-pipe...

Yeah, this 80 thing is a fad as far as I’m concerned too - it’ll never get any sort of cult following.

On a serious note, with some of the pics of the kit lately, I’ve ZERO regret selling my S/C kit. But I’ve always liked turbos, and the steam-driven chem process pumps I worked on for years were just a turbo in principle.
 
Joey, I’m going to need you to build a piece to mate your down pipe to my EMS Exhaust right before the 2nd cat :hillbilly:

All kidding aside your current plan should work for most but if destroying a $1500 OEM y-pipe could be avoided that would be better.

Maybe carry on with your current plan, then design a 2nd piece down the road that connects your downpipe, includes a cat, and then mates up to the 2nd OEM cat.
 
Let us just ponder this exhaust routing business for a moment:

IF this conversation was taking place say 15 years ago, integration of exhaust routing would be much higher on the checklist. On the other hand it is important to point out that due to the nature of the OEM front exhaust pipe, one would have to chop something up to make a final connection.

I would think that a kit-supplied front pipe that went from the turbo to about where the front stock cat inlet lies would be about as good as it gets. The most complicated portion of that pipe is getting it properly connected to the turbo and down to the front cat. After that most any exhaust builder that could fog a mirror could do the rest.

A catless 3” all the way back, sure would complement this kit. I built one for my old truck with an ls in it, it would be nice on my 80. Big magnaflow and a vibrant resonator..... i can see it now....
 
For me a 100% bolt on kit / exhaust is preferred, but I could probably manage to find an exhaust shop to take care of the final part of the instal. Having to tow the 80 to an exhaust shop would be a pretty big hassle if the welding couldn’t be done off the vehicle. That would probably turn off quite a few buyers too.
 
A ride on the flatbed from the house to the muffler shop is one of the cheapest pieces of the puzzle.
 
agree, if install requires towing the truck to a shop, I'd seriously start to question if I really NEED this. I don't have the skills nor equipment to weld, and have to think that would be the case for 95% of potential customers.

True, for those of us with a trailer it would be more just a hassle than an expense, but for those without a trailer or access to one it will just add to the expense of the turbo. Tow services aren’t cheap and having to pay to get it there then pay to get it home could add up. Some might be really stretching their budget just to buy the kit, then add several hundred dollars more to get it installed / finished up might be the thing that keeps someone from buying. I guess you have to pay to play, but the less you pay the better. ;)
 
I have been following this thread since the begining, everything that Joey has done so far is over and above what he could do, he has thought this out and has alot of time and effort to supply a quality product. My 1rst impression of downpipe is that it's perfect for what I want to do. I'm going to buy a single cat and have a pipe made to connect to back side of 2nd cat and go from there. IMO if this is a deal breaker for some people I guess you don't have to buy it. But for the ones that don't know how to weld buy some flex pipe and some clamps ($20) slap it together and drive it to a exhaust shop and get it done, no towing required. I have discovered that you can't make everyone happy and you don't have to. Joey keep doing what you do. It's done when it's done. Thank you
