Sidepipe fabrication?
Has anyone ever had an exhaust shop bend and fabricate pipes/mufflers for under their sidepipe covers? My 71 has the 69 factory lookalike plastic covers on it but the pipes are in pretty rough shape. It's a big block and I was thinking about headers to let it breathe but wanted to keep the sidepipes. Any recommendations?

I made my own, 3.5" pipes under the fiberglass covers.
Used two auger inserts from www.speedwaymotors.com, might be a little loud, 3 was too quiet, 2.5 per side might be a good compromise.
don't cap the center pipe.
The flow very well too!
A search should get some results.

Both my cars have fabricated side pipes... one cost me 400 with Glasspacks and the other about 350 with chambered sweet thunder 2 1/2 mufflers.
chambered exhaust are too loud for sidepipes... Id look into glasspacks but you cannot get them too big or they will push on your side covers and vibrate them, or stick out under the cover.
The other option is to get a 3 1/2 or 4" pipe as the main muffler and install sts baffles.

I have a buddy who is an excellant welder, he can weld wood to concrete and pass xray tests....so....
I am wondering about buying some bar stock aluminum and we design/fab up two outer skins and then use 2-3 thrush non see through mufflers in the middle...have to make an S turn underneath, but my most concern is the noise at ANY rpm/loading, and also burning wife/me legs....
anyone with any experiences doing their own aluminum fabbed shields/cage and any success on the burn issue...??

Sorry I didn't resize these but I didn't have the time... These are for a 1970 BBC car I built last year, 496", T56, evil little car. They started out life as four Dynomax Race Bullets: they were cut, sectioned, and welded back together. A 4" mandrel exhaust stack from a trucking company rounded them out. Once the welds are finished and the set coated they look like one piece, very nice sidepipes. This was on a STOUT motor and as such they're fairly loud.
