everything i have tried wont get the damn exhaust straight! i have a stainless steel racing beat header that goes to a bonez catalytic converter to a racing beat cat back system. no matter what i do the left side hangs low.

i dont know what else to do. i've tried swapping the boots to either side, i've tried twisting it to straighten it out but nothing has worked. it just hangs low. im getting extremely angry at this....keep me from going insane!

 

You could try replacing the rearmost exhaust hanger 'donuts' with hose clamps that you can adjust.

 

What he said. It seems to be quite common to find it hard to get these exhausts straight. And lower on the left does seem to be the typical problem.

 

Would it be wise to do all 4 of the rubber donuts? i tried zip tying it up once but it was really tight and i figured it being so tight would not be good for the exhaust in the long run.

i figured it has room to give for a reason. maybe im just a retard <_<

 

I have the same thing.
My RB exhaust,one sticks out more than the other.
You can live with it or get a welder to make it right.I tried donuts,they don't work.
I use 4 inch hose clamps to hold the exhaust up on the hangers,That way I can adjust the Mufflers a bit to make them sit even.

 

Cut hangers, and weld.

 

My solution (requires no welding or cutting):

I have the exact same setup as you. 1st to do it right get brand new doughnuts for the rear (4). Once you have those, you will need to "adjust" the metal brackets for the doughnuts using a hammer.

My RB exhaust hung low, and I know probably 99% of the people have the same issue. Bend the metal brakets (hooks) like so (assume facing car from rear to the front):

1. Left left bracket - bend towards left
2. Left Middle - Bend towards right
3. Right Middle - Bend towards left
4. Right Right - Bend towards right

This will raise the mounting of the mufflers. You will need to "adjust" accordingly since I can't tell you how many inches to bend, you will just have to bend and take a look at the mufflers till you are satisfied.

All this can be done with the old doughnuts (i did it this way), but I can guarantee you new doughnuts will really help bring the mufflers up and may require less bending of the brackets if you do so.

You can also use a floor jack and a piece of wood to bend the brackets a bit, but a heavy hammer will do the trick. Be careful not to hit the body of the car with the hammer. Place a piece of wood or thick blankets in those areas as a precaution.

Oh and NOTE: as you bend brackets, be aware the distance from the doughnuts to the hanger will increase, so initially trying to slip the rubber hanger on the bracket may take some playing around with them, this is normal.


I didn't think of this, hose clamps are probably another way to go. Racing Beat should start including hose clamps for rubber hanger replacements when they sell you the exhaust....

 

cut and reweld your exhaust. only takes a few mins, and will never be a bother again. you do own a welder right (every one should)

 

jjcobn, i thought of trying that but i didnt know how hard the metal brackets were. i will try this when i get home tonight, and 3vil no i do not own a welder...my dad has everything but one of those!

 

Buy smaller rubber doughnuts for the side that is lower. Just match some up at the parrs store.

 

I've tried that and they just fail more quickly.

Mine hangs low on the left and I just decided to live with it.
Not like it's the most egregious cosmetic flaw I roll with...

 

The small rubber doughnuts at the parts store will snap!! Don't do it.

 

Depends on the diameter of the rubber.

If so, then try bigger doughnuts on the other side!

 

This thread (and posts) smacked me in the face. A nice "DOY!" to me. Use hose clamps to adjust! I cannot comprehend why I didn't think of this.
Also clokker used the word "egregious". I LOVE that word.

This all made my day

 

This is a notorious problem with RB systems unfortunately.. Mine sat lower on the left but turned out my motor mounts were busted and the whole motor was tweaked. Now with new motor mounts it sits perfectly straight with no bending or welding or anything.

 

Hose clamps don't flex or absorb vibration very well, that is why rubber is used in some part of exhaust hangers.

 

I like the sounds of this. would make sense and my engine does have a bit of a rattle back and forth.

i'll try a hose clamp on the one side temporarily until i can get some new motor mounts.

OH! with the motor mounts, do i need to take out the motor or is there some way i can sit it up just enough to pop them in and out? this is my DD so i dont have tons of down time..

 

Ziptie it.

 

I have new engine mounts, problem is still there regardless.

 

go to the parts store and ignore the doughnut style hangers, get 4 of the rubber strip type hangers and take the steel hangers off the rubber piece, all you need is the rubber pieces.

hold the rubber strips up to your hangers to get an approximation of how long they need to be and cut off the excess. the strips should have some pre-drilled holes but they likely aren't the right length, take a 1/2" drill and drill several holes on them for adjusting purposes near the end that now doesn't have any adjustment holes in it. now place them on the chassis of the car hanger and pick a hole to insert the muffler hanger into. you can adjust the height of the cans versus the car by switching which holes you use in your new rubber hangers.

zip ties and hose clamps are janky and will result in your exhaust finally breaking them and your catback sliding across the freeway in front of a soccer mom's SUV, which you don't want because she has better insurance than you do. this fix costs approximately $15 and only requires a drill and a few larger bits and some arm strength or jack under your exhaust while you pry the new hangers on. you will still have to replace them periodically because no hangers seem to last on rotary exhaust, but this is the best and easiest method for evening out the height of your exhaust tips.

also keep in mind your mid hangers are what really position your exhaust, the ones near your fuel tank. these hangers have a tendency to sag but rarely fail because they have a steel sleeve reinforcing them, when they are worn they let the rear sag more and put more stress on the rear o-ring style hangers which fail more often due to the sagging. the mid hangers are only available through mazda. replacing the mid catback hangers provides a more permanent fix to relieve the rear hangers from doing all of the work.
