How to install true duals w/edelbrock TES?

Hello....The edelbrock tes's have stock exiting/stock exhaust flanges. Now I'm really set on the true dual thing....and i'm determined. I can't find an exhaust shop or anyone to do it.. so i'm going to do it myself.

Now ....where do i get some pipe that will connect directly up to my headers w/donut gaskets....or could i just cut my existing Y-pipe and just turn the dumps to face the rear???

thats my hold back...........after that it just seems like i would run some 2-1/2 inch back to some mufflers that dump before the axle..


I have a SC....which is not lowered......soo i'm not toooo worried about ground clearance....I have higher pro tires also..


thanx..

rob. .....I'm looking for that classic sound...

If I were you, I'd just cut the Y-pipe and be done with it. Or you can try to buy the TES dual cat pipes (the pipes that replace the Y-pipe), but I dont know if they are sold seperately...

That's similar to my setup, I've got Hooker 2460 shortys. I was in the same boat you were, I couldn't get an exhasut shop to even consider working on it, so I built it myself and was very happy with the results and it's much better quality than any shop could have done. So here's how I did it.

I installed the headers to get an idea of where I wanted to run it. I decided for the passenger side that the best place for the muffler was where the stock cat went under the pass feet area (latge bump in floor), for the driver's side it had to go under the floorpan right after it goes up slightly by about an inch. Then I got some flexible duct joints in 3" size (you can get 2.5" size also) so that I could mock it up. I had to get a few of these for all the bend, but they're cheap. If you were wondering, my grandpa is a retired sheet metal worker so he's got all kind of good tricks. Anyways, I took those joints (and pieces of straight ducting) and bent them (roughly) to where I needed them. Then we took and bent the ducting to the collector rings so that we could bolt them to the headers and get them perfect. We then tweaked the joints and duct taped them together so they wouldn't move when we took them off. We then tried to find someone to bend the shape, but were unsucessful (we could have had it done in 2.5" pipe, but I was uneducated back then and wanted 3"... different story though). So since we could find a shop we decided to do it ourselves. We didn't have a pipe bender so we had to cut the pipes to fit. My grandpa made some templates that used the same angles as the duct joints had for us to cut the pipe. We cut all the pipe and welded it all together at angles instead of being bent (I'll attach a pic). We did that for the whole thing and made exhaust hangers that attached to the tailpipes to support them (clear in the pics).

Anyways, that's what we did. It was a pretty complicated process, but it turned out very nice. I'll post a few pics now to give you an idea, but I'll scan in some close up pics tomorrow to post up for you.

Passenger side...

As you can see the paint didn't hold up to well, don't use the cheap $5 a can paint from auto parts stores, use some good VHT flamproof stuff. I'll get some more pics soon and post them up. BTW, this system will be for sale soon when I swap in my 406 (going with longtubes and dual glasspacks). If anyone is intrested, email or pm me and I can give detailed pics and specs.

Jeez, I think thats why thirdgens get stereotyped as hillbilly cars. Perfect example right there.

It was a hard setup, me, my dad and my grandfather put many hours into it. It all had to be cut and welded together to make the bends since no shop would bend it for me. We spent a lot of time just figuring out the right angles to cut the pipe at to form the bends. This isn't something any guy with a welder could do....

Looks like it's tucked in there as close as possible considering the location. The thing that seems wrong is its rusty, hard to stop here on the humid east coast. I did the weld it yourself exhaust & it's definitly not for beginners. Be proud of your efforts.

Yeah, the rust doesn't look very good, but like you said, hard to avoid around here. I'm going to sandblast it and paint it when I have some spare time (few years down the road if things stay the way they are... lol). When I paint it I'm getting good VHT or that Black Satin stuff for it. I won't use that $5/can stuff from Autozone anymore...

Holy hell, is there anything you DON'T bottom out on? Sorry but, I wouldn't take that setup if you paid me. Catch one bump and goodbye exhaust..manifolds or headers. It'll rip everything apart...
