Another Question for you folks with Headers
So you've got aftermarket headers. What do you use for the rest of the system? There seem to be only a couple of choices...
1. Order standard Corvette exhaust. Cut off the part that would normall curve up and bolt to the cast iron manifold. Weld the rest of the exhaust up to a reducer that bolts up to your headers.
2. Have someone else make a complete custom system from the headers back.
Is there another alternative? I brazed my last plain steel system together and it lasted 20 years and still had no holes when I removed it. Is stainless steel worth the cost? Is it hard to weld? Do you put up with sections that are "compressed" / flattened where they make bends?
So many questions... :rolleyes:
Thanks...

Hedman makes these "extensions"
I have a pair of these things that did not quite fit... :( Some forum members have had success with these things but had to cut and weld them. you could also have an exhaust shop bend you just these pieces to connect your headers to the rear pipes.
Reading your post, it is not clear if you understand that a "standard corvette exhaust" consists of a front pipe clamped to a rear section (connection is just in front of the crossmember). So what you need to do is modify or replace the front section, and connect it to the unmodified rear section.

An economical solution to the problem of hooking-up hedders to an existing exhaust system. No longer will the hedder installer have to fabricate or "jury-rig" a hook-up. An "S" bend to allow for clearance of drive-shafts, cross-members, brackets, braces, etc. Comes in three sizes. Also available with a universal flange which will allow hook-up to virtually any hedder manufactured

Those Hedman pieces look good, but boy, the "reducer" part is pretty abrupt! Still, not a bad idea...
I have access to welding equipment. I guess I though everybody welded their pipes in nowadays looking at all the undercarriage photos. It just seems like the clamps don't hold up for long except to hold the exhaust tip on...

When I had my custom exhaust made, they welded the system together and welded in flanges where I would need to take it apart to remove things like the drive shaft and gas tank. :party:
