Tim:

Here is what the hanger looks like that is off the second "outrigger" from the main fraime rail on my car. It's just a two-ply section of thick rubber:

Hopefully you can see the location easy enough. The box hanging down just up from this location by the first "outrigger" is the pedal box on the driver's side.

Oops. Wrong thread.

Allen,

This is very helpful

By chance do you have other photos that show attachment to the muffler / tailpipe ? Thanks!

Why thank you ... it's an impressive arrangement of bits and pieces

Just to clarify, I was talking about the 289FIA.

Cheers,
Glen

ERA builds some very nice stuff

Get some undercoating on that spare tire tub, quick! Other than that it looks awesome!

Well *13* will be proud …

Not quick mind you, but a few weeks ago I finally painted the spare tire tray.

As noted in another thread, I used Klean Strip Prep All, Transtar 4613 Black Primer and SEM 39143 Trim Black Paint.

Most of the time was spent in preparation as is usually the case when painting. Masked the area, cleaned the surface, and draped the entire car with sheets, so no chance of overspray.

Two light coats of primer and three light coats of paint. The end result turned out as good as I hoped for.

Geez, that's beautifully done. This is one of those "slip a mirror underneath" cars, when you happen to show it.

Tim:

Sure, no problem. I have the FIA side exhaust, but at least you can get an idea of what the design of the bracket coming off of the pipe looks like. I assume you would be able to do much the same with your set-up. I'll throw a tape measure on it so you can get the scale and post an update here:

^ Bump - updated with pic.

If you need anything else, Tim, just let me know.

Allen,

Thanks for the photo. The FIA side pipes are different setup, but correct me if I am wrong, a similar configuration with attachment to the header collector and one rubber isolated mount near the outlet, correct?

Was able to work on the exhaust last night. So far we have shortened the header collector 1" to bring the head pipe up closer to the car, probably have a bit more to take off. We have the muffler set between the frame outriggers and spaced about 3/4" from the floor, so the location of the muffler inlet, ultimately sets the length of the collector. Will have a rubber isolated hanger that attaches to the tail pipe near the output side of the muffler. I have a variety of hangers and will try to use an existing hole in the frame. Want to have the entire setup slip fit and bolted together for serviceability and modification down the road. Will post some pictures as things progress.

The ERA FIA setup attaches at the front to the collector and in front of the rear tire in one spot to the frame.

Right, what Jim said...only supported by the frame in one location as pictured. The other end is supported by the header/collector (slip fit). I am planning on changing the header connection from a slip joint to a ball and socket joint like the pieces JEGS offers: JEGS Ball & Socket Exhaust Pipe Connectors - JEGS

I must admit I assumed this wonderful idea from Wolf K. I plan on playing around with making a set of "competition" pipes over the winter and this ball/socket joint would make removal/installation and bind-free alignment a breeze. After taking my current pipes off a couple of times, I've found that I'm not a big fan of the slip-joint connection with the little welded on tabs and 1/4-20 through bolts that keep the slip joint secure.

Allen and/or Tim - do you get much leakage with the slip joint and no clamping? How much engagement is there?
Cheers,
Glen

*13* · #16 (**permalink**) 10-18-2011, 05:18 PM

About 3" overlap at the joint? I can't remember for sure, but that's what I seem to remember. I haven't noticed much leakage. Of course, there's not much back pressure with glass packs as a restrictor

Glen,

From what I can measure, there is about 1-3/4" engagement. Don't have everything assembled and running, so can speak to exhaust leakage. Some cars seem to have a bit, others are OK ... maybe a variation in tolerances?

Dangerous Doug · #18 (**permalink**) 10-18-2011, 08:47 PM

I get leakage, and it is getting annoying. I really cooped in the copper gasket sealer, too. I opted for some stainless steel wrap straps and have cranked them down tight after hooping on the copper gasket on the slip fit.

I am going to copper gasket goop it one last time and clamp it with a standard U-bolt (stainless steel) to see if I can get it to seal.

If that fails,welding three-bolt heater flanges on with the standard exhaust donut, just like Mr. potatohead.

Speaking of... Anyone see Larry Davi around I his ERA?

I used a "Turbo Flange" on my exhaust set up. It works very well and only has one nut to tighten down and it seals it up. This would work very well with different exhaust set up's too. Here is example of what I got for my car :3" V-Band Vband Clamp Flange Flanges Turbo Exhaust Stainless T70 T72 GT35 | eBay

I still used a little ultra exhaust sealer between but I really don't think it was necessary. I might have some pics but still don't know how to post them here! Regards, Matt

Thanks guys for the posts and info … keep 'em coming. Did some more mock up this evening, still working on the pipe from the collector to the muffler. Located the muffler in it's spot between the frame outriggers and used a 3/4" piece of foam on top of the muffler as a spacer.

Then cut the tail pipe where is fits onto the muffler and hung the pipe from the fender with blue tape. Let me know what you think … maybe move the tail pipe a bit closer to the front of the car and trim of about an inch or so from the end?

Looking at using a hole in the inner fender gusset, to attach a small triangulated support a bracket that will be isolated with rubber, bolt to the frame though an existing hole, then extend out over the tailpipe where it will be welded. Hopefully will be able to fabricate that within the next few days.

Here are some photos …

On the ground (well almost)

Muffler and pipes will be flat black when finished
