Default Tri-Y Headers

Thinking about ordering a set of Stan's Tri-Y headers today. My car is my daily driver for now, and I'd like to get just a little bit more power out of it. I know that contrary to anyone who has standard 4 into 1 headers, Tri-Y headers are better for lower compression and lower RPM motors. Does anybody else have any experience with Tri-Y headers? And do you recommend I take it to a muffler shop to have them connected to my new exhaust, or try and do it myself?

I dont have tri-y's on my car, but everything I've read says they are a perfectly fine choice for the application you are talking about.

If you are already running duals, you just may be able to do the hookup yourself. However I've found that unless you are handy with a welder that final hookup is best handled by a muffler shop.

If you are still running a more or less factory exhaust on your 81..forget it, the hookups arent even close I'm afraid.

I'm running a 2.5" MidAmerica Motorworks chambered true dual system, but they connect at the factory location. I'm figuring that wherever I take it they can just cut the pipes where they need it and to a little welding to make it all work.

Thinking of putting the same on my car. I've read off of a couple of different sites about the same thing - tri y's are better for lower rpm (up to 5500 rpm) engines as far as exhaust scavaging.

Ya those are the exact ones I'm looking at. Stan's makes them. I'm just wondering how difficult it is to install with the air pump and EGR and all that fun stuff to disconnect.

I don't think there are as many people who have used these headers who can comment on the install vs. long tubes by Summit, Hooker, etc. My guess is to call Stan's and talk to them about it. I plan to take the EGR off my car when I put these on. I plan to change the heads at the same time I would put these babies on. My plan was to call Stan's and talk to them. I just won't be doing this until the winter.

nothing wrong with a tri-y if its developed to your application.

I would DEFINATELY go with the Tri-Y instead of sidepipes, especially if you're not racing your car and tend to stick around lower RPM's more than higher ones. A good set for a C3 is made by Stan's Headers. Here's the link: http://www.stans-headers.com/tri_y.htm

They give a LOT better scavenging than 4 into 1 headers at lower RPM's and for lower compression motors. Definately superior to standard headers for a street car.

Got an old school hot rod book "How to Hot Rod a SBC', the author thinks tri y's went out of style because racers don't use them and wondered if guys would ever wise up and go back to them since they provide better performance for street driven hot rods.

That's the exact reason they're not more widely used. Y's are waaaay better for street use, but since the racers use 4 into 1, they must be better, right?
