Just wondering about DIY exhaust

I don't own a welder and have never used one, but I'm fairly good at soldering. Can a custom exhaust be soldered together or will the heat of the exhaust just undo the soldering?

If you can't weld, use exhaust clamps.

you can use 2 1/2 copper pipe and fittings and solder it, i don't think it will get hot enough to melt the solder

I was thinking about trying to use the stock pipes and just cutting out the old muffler, resonator and cats, and replacing them with new muffler and new cats. I would probably leave the third cat in front of the resonator in there. I'm just throwing around ideas. The copper might look cool, but copper is expensive and not to mention valuable to thieves. I probably wouldn't clamp it all. If it can't be done I just wont do it now and wait until I have the money. I was just wondering. BTW, which would sound better, just removing the resonator, or just removing the muffler. Or would it sound bad either way?

Personally, I wouldn't do either one. For a V6, I'd replace them both with something. And if your going to replace those, why not just do the whole thing, new cats, resonator, pipe to the rear, and muffler (or mufflers if you choose dual look)

I'm thinking, something like this maybe.
http://forums.tccoa.com/showthread.php?t=120195
But I have a few things I'm wondering about.



Isn't that a cat he is replacing with a muffler? Is that legal? Could you put a new cat in after the muffler to stay legal?





I think I would place the second muffler sooner in the pipe then run pipes to both sides of the car. A DOR setup instead of a DOSS setup.


Melon, do you know anywhere that recycles cats around here? If I can find a place I might recycle them so I can buy the magnaflow cat setup, then run a custom set up from there back.

Nope, no idea of anywhere local that recycles them. I would think maybe any junk yard would take them? Or talk to an exhaust shop.

And while it may be illegal, Nebraska doesn't check emissions and whatnot - or atleast none of my cars have ever been checked - so you wouldn't have to run the 3rd cat if you didn't want to - I've just got 2 cats on my 94.

sorry thats just too funny. even if solder could hold up to exhaust temps you'd need a **** load of solder. plus solder under vibration cracks and would split. you can use clamps but i suggest make the exhaust and pay somebody to just weld it together it'll be faster and cost less. plus how do you plan on mounting the hangers to hold the exhaust up?

uh... solder them on... jk, it was just an idea. I just wanted to know if it would work, and now I know it probably wouldn't. I'm going to be working at a golf course on the maintenance crew and in the maintenance building they have a full size lift like a full time shop would have, and I would think they would have a welder too, but I'm not sure.

These are my favorites:
a 96/97 sport I think. Has the stripes, but says lx on the back, did the sports say something different?
http://www.youtube.com/watch?v=pyBUv...e=channel_page

V6 like what I have, so it gives me hope. Doesn't sound nearly as good as the Sport, but I don't think it's too bad for a V6.

i can assure you 100% that lead aka solder will most certainly not hold up to the heat vibrations expanding and contracting of the exhaust pipes.

nope 97 not sure on 96 but are both probably the same.

those v6 will run up and down on v8's all day long stock for stock and even with some mods on a v8 it will still walk up and down on a v8. the thing with the supercoupes is more power less weight which is key in any type of racing. you want the most power with the least amount of weight.

v8 superbirdy,
I'm not trying to jump down your throat, but stop posting incorrect information. A 5-speed 95 SC outweighs a 4.6 car by a small margin, an auto SC outweighs a 4.6 car by almost 100 pounds. The issue is clearly not mass.

That is all.

lowered, koni sport adjustables, 4.30 tl in aluminum housing, mark 8 trans, j-mod, 93 mark viii ds, antenna hole=gone, kooks headers 1.75" primaries, 2.5" catless duals, midmount magnaflow, 96-97 sport wheels with 255/50/16 sumitomo HTR Zs, optima in the trunk, new motor...94 mark 6/6/08

That V6 isn't a supercoupe, fyi.

And coolhandzep, how does an SC out weigh a 4.6L? Surely the supercharger and all that doesn't make up the difference, then another 100 pounds after that.

The reason I brought up the SC thing is because v8 superbirdy stated, "the thing with the supercoupes is more power less weight." I am fully aware that the youTube video was not a Super Coupe. Look it up, SCs weigh more as released from the factory, end of story. I got my information from the Manufacturers Motor Vehicle Specifications 'booklet' from Ford for the Thunderbird.

it does, all the crap on the top and front of the motor is where the weight comes from

Where do you get the extra 100lbs? V8 and SC's are both in the high 3700lb margin.

This should be noted that these are the curb weights directly reported by Ford.
The Manufacturers Vehicles Specifications 'book' is my source.

1995:
V6 NA 3536 lbs
V6 SC (auto) 3752 lbs
V6 SC (5sp) 3724 lbs
V8 3673 lbs

That's from Ford. I know there are variables, but I think specs from the manufacturer are a good baseline comparison. Anyhow, all of this came from me trying to tell someone that SCs were not lightweight, oh well.

When I said that the video wasn't of an SC I was replying to this post.

I was just surprized by the SC weighing more, I wasn't meaning to argue. Thats weird that they do.

I'd argue with that, too. According to what I've collected, a stock '95 SC will run a quarter in 15.2 seconds, and a stock V8 will do the same in 15.8. A wide margin to be sure, but depending on your "some mods", a V8 will definitely be able to keep up with an SC.

i duno about those reading from FORD but i work part time at scrap yard as a security officer and trucks comes and goes and i have to write down their weights. One day i decided to weigh my 1990 FORD THUNDERBIRD SC AUTO. It was exactly 3900LBS me outta the car looking at the computer from the office and its is BONE STOCK no modes AT ALL not even CAI and no stereo in the trunk...TOTALLY STOCKK....plus i had my fuel tank at half...so how come its more than of wat FORD reported in their ''BOOKS''....


and o ya i m sure if our SC's were 3.8 V8 S/C instead of V6 they will run way smother than wat they have today and probably we wont have HG problems...

Sounds right to me.

Those sc's that weigh in the 3700's would have to have the bare bones options to get those figures. Every option plus a tank of gas will put them in the 4000+ range.

I always thought it was all the options that added weight to the SC cars. I have a 92 sport am I correct in thinking its the lightest t-bird, except that I added dual power front seats, and it is a sunroof-less car

I've always done clamps on my vehicles, makes it easier to dis-assemble if need be and around here welded systems don't really last any longer anyways.



could always use band-clamps, they seal the best.
