Yet Another Sidepipe question

[Dennis H.]

I have a set of GM sidepipes on my 65 that are in good condition overall except for the pipe running from the manifold to the side exhaust chamber which is rusty (everything else is fine).

Has anyone ever had new pipes bent and rewelded on to keep the GM factory chambered pipe and chrome tip?

Yes I had done this, had a local guy bend the pipe to matct the original front section manifold to muffler. I cut off the old and welded on the new pieces.

Could not tell from original mine was all 2 1/2". A 2" to 2 1/2" will be a bit more welding but should not be much difficulty as long as everything is lined up prior to tack welding in place.

Thanks Gene, I have 2 1/2" manifolds so I won’t have to mess with the 2" to 2 1/2". Just seems money wasted to spend $450 on repo pipes.

I do have a bend in the right chamber that happened when putting the car on a trailer but think I have a good plan to bring it back straight, just need to find a piece of pipe (cut in half) with a inside diameter the same as the chamber and work it out on a press.

i understand sweet thunder sells just the head pipes in correct carbon steel. i just sold a set of 2 1/2 SB pipes and took note of the indents and draw marks as well as the fact they are one piece. i do not think sweet thunders are like this, bill
