is it possible to weld my exhaust to the hangers? so i can remove the plastic dinghies (thick black rubber band) has anyone done this? if so does anyone know how to weld and possibly weld mines for some $$ thanks!

 

why would you want to do that?

 

cus my exhaust keeps shaking and i want my exhaust to be a little higher than it is, its like saggin

 

You should see my exhaust it falls off like once a month... it's awesome.

 

haha wow that sucks! well i still need to find someone with a welder. Btw do you live close to milpitas? and what other work do you do besides smog at your garage?

 

Just smog... I do help club members with various car work though.

 

oh sick how much is it to smog? cus my buddy needs to get smog because the old owner of the car gutted the cats and hes worried that it wont pass.

 

You can weld it to the hangers, sure. There is a reason that exhaust systems use flexible rubber rings to hold the exhaust to the chassis though. If you weld it you'll get a lot more engine vibration.

 

wow that explains everything thanks! no welding for me then

 

Have you replaced your rubber hangers? You'd be surprised how much bigger your old ones are from stretching compared to new ones.

 

+1

Sometimes putting on new rubber hangers is a pain in the *** cause you need to stretch the **** out of them to get them on the hooks... having the right tools helps LOL

 

A couple long screwdrivers for leverage?

 

The exhaust needs to move because the engine and trans move on their mounts, and there's almost no flex in the exhaust. The exhaust also expands measurably as it heats, and without flexible mounts you're likely to break something.

 

Weld to tubing directly to the frame rails. I saw it on a race car. Do it.

 

What i have done in many Road race cars is use small link chains you can buy at your local hardware store.I have done this many times and have had many success.I do mufflers for a living and i have tried other type of hangers on rotaries and they all melt.

Here are some pictures of our E production SCCA Rx7 FC.....This is an exhaust system i built for this car check it out....

 

How do chains provide ANY dampening?? What the hell is going on, buy hangers like a sane person!

 

Yeah it's not going to pass with gutted cats. Tell your friend to get some cats in.

 

Well assuming the chain links don't rust together like it appears to have already done on 616's race car, the chain links would allow the exhaust to bounce vertically and swing horizontally. They would vibrate like a mother though

PLEASE someone do this to a street car. I +1 Renton's idea of welding the exhaust to the frame

I have a feeling that any stiff metal connection between the frame and the exhaust will vibrate so loudly it may mask the exhaust noise. Take that coppers!

 

New rubbers and shorter hangers.

 

Bolt it to the gas tank. With wood screws.

 

^ As a professional auto mechanic/smog technician... I would have to say +1 to the gas tank/wood screws idea. It makes a lot of sense.

 

zipties.

 

You can also try using radiator hose clamps for exhaust hangers. Zipties don't work. Even metal zipties don't work. You can also just try running no exhaust so you don't have to worry about hangers.

 

use many zipties.

 

NO NO use a strap down......LOL
