Maybe a dumb question but is your hanger square to the headers? Or is it that one header just isn't long enough?

I'll be selling a slightly used (<750 mile) Triad 914/6 muffler if interested. Looks great, sounds nice, just too loud under load for my tastes.

I haven't decided on which muffler to hang yet. I have two....2 in 1 out...and 2 in 2 out sport type. I have pics posted earlier in this thread.

The bracket can be bent back in to be flush with the header flange. The big problem is the horizontal positon being to high.

I'm not familiar with this type of hanger. Where can I find a pic...Maybe Armando's site?? This would solve the hanger issue but wouldnt address the muffler not being level...


Yes, I think Armando got those from Eric. I have an unused Engman hanger if interested. I think the GT bracket provides better support though.

Brian when you measure from the floor to each header flange is there a difference left vs. right ? If yes is the difference aprox. the amount in the pic ? How does the other side line up ? How tight do you have the header hardware ? I would loosen the header hardware and slightly tweek the header so it lines up. Leave the mounting bracket loose also. Then slowly tighten each one to see how it goes. You may find that it will all go together. Remember you are using various aftermarket parts ( engine mount, headers etc. ) and it doesn't take much stack up tolerance to give you what you have. Mine was off a little bit and it worked for me and I have no leaks. Hope this helps.

(IMG:style_emoticons/default/agree.gif) I had the same thing when I backdated my 4 with SSI exchangers. I loosened them at the heads, and they were willing to line up with the bracket. I put the muffler on to hold everything in place and tightened them back up at the heads. Problem solved. (IMG:style_emoticons/default/wacko.gif)

Great advice Rick. I will work more on these suckers and see what I can come up with. They are mounted tight...without gaskets. I know the gaskets will make up some difference but didnt think it be enough. I will keep my thoughts positive and keep you posted.

I thought about modifying the existing hanger as well. It will just bother me that the muffler won't be level and will look a bit "off". Very curious to know how it could have gotten bent....





This is really common.

1. Cut the old hanger so you have about an inch of free space between the end and the flange.

2. Get some 1/8" mild steel stock and cut/round/drill so you have a tab that will bolt to the header.

3. Mount the muffler, put the car on the ground, and level it by jacking.

4. Clamp the tabs to the hanger and tack weld.

5. Disassemble and fully weld the new joints.

James Ellisor's was done like this. Ask him for pictures.



-OR-

Bring it up and I'll do it for you in return for lunch.

I would pull the header, bolt it to a strong support like a table or work bench like a jig and bend it until it fits. If you mount it well to your support the integrity of the flanges will stay intact and allow you to put the required pressure on the thing to bend it. We're only talking about a small bend over a long run. That's how we make boat railings fit.
I agree, having the muffler askew is unacceptable considering the quality of the rest of the car.

Been delayed once again with the project. I will be rubbing on this muffler set up in the weeks ahead and appreciate the comments/suggestions. I'm sure a solution will be found with all your help. Here are some pics of the two different mufflers I have to use on the car. Just not sure which one will be fitted first....I know the sound of the sport will be nice...just not sure if it will be too loud.

Very Nice Brian. Looks like you will be ready for the Ramble in the fall.

WOW! I've been down for 2.5 months and am ready to get back on the road! Impressed with your patience and attention to detail...very nicely done. Enjoy the finished product and great story.

PS - Someone mentioned the "Ramble" in the fall, what are the dates???

If it's a daily driver, you may not like the sport muffler "at speed". Around town they're perfect.

Also...

So, you experts think that a muffler hanger like that is better than modding the stock 2.0/4 exhaust hanger?

It's better 'cause Eric sells them!

Seriously, I like the stock 2.0 muffler hangers. It does look like Eric's gives more support, but I've yet to install one.

Choose your muffler carefully. I've been in a couple 6 conversions that had an unbearable drone at cruising speed.

I'm a big fan of the stock 6 exhaust system, but hey that's just me.
