So I've been searching on who makes a 3"HFC but all Im comming up with each and every time is just the damn 2.5"HFC from random tech, APS, AAM, Crawford, Kenitex, and the like.

So my question is who makes a 3" HFC. If Im missing it call me stupid and point me in the right direction. But all I keep coming up with is like 20 pages of crap and only a handfull talk about HFS. Of those I have not found a mention OF 3" FHC.

Thanks

Mike

EDIT: Prefferably the weld in. Im looking at the SVRTech 3" with the X pipe.

it seems like they're talking about it as 3".

 

They are talking best case scenerio. A for instance if x and y then z. The link you sent was for a suby. The 350Z's were only the 2.5's. So no dice on the 3" HFC's

 

get it custom made. it wont cost more than what a 2.5'' would cost.

 

Funny is the Red bold says Suby, but the product title and item says 350z/g35 coupe. They made a mistake.
How come you don't want the down pipe? You have a turbo set-up?

 

Well there may be a chance that Im going to germany and the only thing between me and the Autoban in the Cats. Yes I have TT's. But Id rather have the HFC and Autoban than Tests pipes and storage.

You see my math.

And what do you intend to bolt 3-inch high-flow catalytic converters to? 3-inch headers? 3-inch exhaust? Where do you find those?

 

Nope thats why I was looking for weld in... There are a couple of manifold back 3" exhausts that have plenty of room for a HFC and an extra bung for my AF Guage (before the cat).

 

I talked to RT on the phone a couple of years ago, and they told me they have 3 and 4 inch cats with metal substrates. You have to get a muffler shop to weld on the pipe and flange. Edit: You can also buy muffler with 3 or 4 inch inlet/outlet and have custom exhaust made cheaper than the fancy store bought items.

 

What high-flow catalytic converters did you buy?

 

As of right now, none. My focus is getting the engine in, UTEC base mapped for breakin, break in, and a killer tune. Goals of 550 or so low boost and 650 or so high boost.

So the exhaust is lower on the agenda right now. Ran into some issues with my build that require attention. So over all this set me back about 6-8 months.

 

Best wishes with your project.

 

Random Tech definitely makes 3" and up cats. I've put them on Supras before.

 

Man if you want 650whp on high boost, screw the cats. They'll get ruined anyway because you'll run very rich at those power levels.

 

just get some cheap 3 inch cats and clean them out... do they just do a visual inspection in Germany to allow you on the autoban?

 

We will make a 3" cat for you. It will be the same design as our 2.5 inch but larger. If you are intrested let me know...Thanks, Tony
