Have any of you guys tried these? I currently have the Hi-Po manifolds and H-Pipe, with no mufflers and love the sound, but am looking at getting the Tri-y's with the 1 5/8" primarys, no mufflers and side exhaust. I've heard this has a "unique sound". Is this someones way of saying they sound like crap? Just wondering if any of you had tried this and liked them. Thanks in advance for the replies.
Tri-Y Headers?

Tri-y's are junk. I had a set on my car and toasted a whole bunch of starters. It wouldn't have been so bad, but they make it hard to change the starters. Also, they leaked even with copper gaskets and made less power than they 1-5/8" shorties that I put on. Tri-y's=junk, except for the ones made by Doug ?Thorley?.

I've had Tri-Y's on the car for 6 years now, using the original (GOOD Fel-Pro's) header gaskets, and the original Autozone starter. Neither have been replaced.
As far a side-exits. You really need a muffler, otherwise they do sound like %^$&.
Here's a picture to ponder. As far as sound - If you've heard a late-model Roush, it would sound very familiar.....

i use tri-y'd, haven't had a problem yet. i put a heat shield over the starter to (hopefully) circumvent the frying problem. incidentally, i run dynomax race magnum bullets, and dumped it out the side. it's a nice setup, i recommend something like that if you're gonna dump them out the side.

I also have tri-y's, I really like them. Never had any starter problems....but then again I use a small late model style gear reduction unit. They fit well, better than most other headers on the market, they have good ground clearance also, unlike other longtubes(especially important on lowered cars). Their design promotes good midrange horsepower and low end torque, right where a street car needs it most.
As for sound, I don't know how unique they are really. I would maybe say they're a little higher pitched than others. My car kinda screams instead of roaring.....if that makes any sense. Just be sure to a good quality set instead of the economy ones, same rule applies to any thing else you buy too I guess.......

I have the ceramic Tri-Y's and love them... just use some good quality exhaust manifold gaskets, like Felpro, and invest in some Stage 8 locking header bolts to keep it all tight.
Don't mess with chrome Tri-Y's they blue like crazy and are a real mother to shine.
You will definitely need mufflers. Not only will it sound like crap, you need a little backpressure for low end torque. Personally, I like the FM deltaFlow 50's, but you might like the 40's better.

I've got a set too, except mine are on an 89 V8 Ranger. They fit well, no leaks ( mr gasket gaskets) one collector doesn't even have a gasket and it doesn't leak. Never fried a starter with em. They even worked great on the 400 horse Canfield headed roller motor that I had before. I've had full length headers on a big block Stang ( Hookers) and these tri-y's aren't near the trouble that those were.

Has anybody in this group got tri y headers to work with the T-5 cable conversion?? I am buying a mustang steve complete setup and want to know if I am going to have to ditch my headers... 
Tri-Y configurations generally make more low and midrange torque at the expense of high end horsepower compared to long-tube equal-length designs. This was usefull in the early Cobras and Shelby's since they only had 289ci to work with and anything that helped the torque was a good thing.
I say that is a general thing because there are so many different designs/manufacturers out there. I think these variances in design/manufacture also account for the varied experience you are reading about here.

As above...that depends on which headers you have. I have Headmann Elites and there's gobs of room for any clutch setup I can imagine.347Fastback said:Has anybody in this group got tri y headers to work with the T-5 cable conversion??

Maybe you didn't read my previous post, I ran a set of Shelby type tri-y's on a Canfield headed 40 over 302 and they worked great, pulled all the way to 7500 rpms. This was in a 3800 lb Ranger with a 4 speed and 3.73 gears, and still ran 13 second quarters. They'll work great in an 800 lb lighter Stang too.65stang311 said:
