I am in the process of putting the dual exhaust on a 67 Chevelle and have run into a problem on the exhaust hangers. The exhaust system is hooker headers into a pypes x-pipe with dumps, then into magnaflow offset-offset mufflers and tail pipes from stainless works.

The problem is with the x-pipe and mufflers level from front to back and the tail pipes in a good position, the muffler/tailpipe are atleast 4" below the stock exhaust hangers. Hopefully the pictures attached will show the problem.Is there anyone here who is using the pypes set-up on a chevelle? What should I do here? If I raise the mufflers it has them tilted way up hill and raises the tail pipe th where it hits the frame as it crosses under it. I thought about removing the rubber straps from the current hangers and putting some longer ones on them to lower the clamps 2-3" and then pulling the mufflers up. Any help here???????

Thanks
Larry

I'm going to start together with my powdercoated frame tomorrow. I was going to go with the Pypes complete package in a couple weeks. I thought mounting would be figured out and explained. You mean they just furnish some bent up pipes to figure mounting on your own?

The pypes x-pipe I bought contained- 2 header pipes (short pipe from the collector to the x-pipe), a x-pipe (half of it is visible at the bottom of the 1st picture) and then the 2 connector pipes (visible between the x-pipe and muffler). Putting their x-pipe set-up together is not hard, its hanging the system to the exhaust hangers, that's giving me fits. This is the 2nd pypes x-pipe with dumps that I have installed (66 GTO the 1st one) and I really like the set-up, especially with electric cut-outs on the dumps. Don't worry it is a nice set-up and other than the hanger issue easy to install.

Any help here? Iwold like to finish this over the holidays if possible.

Dont know if this helps but i hung my pypes system so it was as hidden as possible, the mufflers do go up slightly and i used whatever i needed to hang them in the spot that looked best. As its not factory correct use what you need to get them where you want them. JMHO Ralph

The biggest problem I see is that you have a piece of wood stuck between the pipes!

Ok, are you running the tail pipes on the outside of the frame rail? I have the pypes system (in fact, except for the color of the differential, our cars look the same) and the explanations are 'weak'. I went to their webpage and looked at the various pictures of finished and partially finished (frames) that they had and it helped me much.

I tried to run them inside the frame and had serious problems. (duh) But then, when I put them outside, everythign fit fine.

Ralph67- I am agreeing with your comment on do what you have to to get them to hang where I want them.

Stalkingbear- the pipes from the x-pipe tend to taper inward, so the block of wood is speading them out so the are equal distance apart at both the front and the rear, this puts the mufflers closer to the center of the hangers and increases the distance from the driveline. When we get everything hung correctly, the block will be replaced by a metal strap welded to both pipes to keep this distance. I am running the tail pipes outside the frame just like you have. We started at the headers and worked our way back, tack welding all the x-pipe together up to the mufflers.Did you hang the tail pipe and mufflers first and the work forward (it looks that way in your picture)? Maybe that is the way to make this work. I think if the muffler clamp was 2" longer I could solve this with very little rise in the mufflers. One other question who's brake hose are you using? look at the slack in yours as opppsed to mine. Mine came from Matt's Classic.

Thanks
Larry

I sort of like the wood option...... (kidding...)

I started at the rear and worked forward (ahem! like the directions said. Ahem.)

The brake line is from Fine Lines I believe. Yours looks pretty tight to me.

Oh, in the showroom under 1965, you will see the pipes laid out prior to installation. THe mufflers are hung but the pipes are not installed yet... I had to stop for a week because my falther in law passed away. Sigh.

But, after Christmas, I'll be back on it!

Stalkingbear- directions....directions, darn amazing what happens when you read them. I don't remember there being a set in the box, put I just printed them out and will try this following the DIRECTIONS. Thank you for taking time to answer my question and get me to read what I should have read first. My condolences on your loss.

Thanks
Larry

Thanks buddy... post some pictures when you get it done, please. It looks good!

My plans include a 'gearvendor' unit so I will need to install it first to see how the rest of the exhaust will fit together... I would hate to have it all done and find out I have to cut it apart to fit the overdrive.

We finally got the exhaust hung on the chevelle. Took a hanger set from AutoZone and used the straps on it to replace the ones on the original muffler hangers, which allowed us to lower the hangers 2-3" and went from there. Also got another hanger kit from AutoZone and replaced the rear tail pipe hanger to get a better fit. Right now about a fourth of the muffler is visible below the frame and once the body is on I don't think you will see any exhaust. Here are some pictures. Yes the excess straps will be trimmed to look good.

Thanks for all the advise.

Larry

Glad u got it done Larry! Ralph

Looks good, Larry!

I spent a bunch of time looking at exhaust fit when I put in a Summit 3" setup on my '68 El Camino. One thing that strikes me about the Pypes system is the straight pipes going into the mufflers. Most systems have a bit of an offset step just in front of the mufflers. This offset helps out a lot in that you can rotate it up to raise the mufflers. The general layout is to run from the headers in close to the driveshaft because the floor rises there. Then at the rear it spreads back out to the mufflers. There are also raised areas on each side for the mufflers to fit up into.

With respect to the block of wood... I had a warpage issue with my pipes after I welded up my home brew H crossover pipe. You can spread the pipes out a bit beyond where you need them and then apply heat with a torch to an area of the pipe. The pipe will bend out where you need it and then you will not need the extra metal piece in there.
