sidepipes questions
I'm starting to consider sidepipes for my '79, whether I decide to put the 454 in 'er or find a small block instead. I've got a few questions;
1. How hard is it to install sidepipe exhaust (I assume small block is easier)? Does it having mounting points anywhere other than the obvious header to exhaust port locations?
2. Does sidepipe exhuast eliminate most of the C3's notorious interior heat?
3. Is there a BB sidepipe set up that isn't TOO loud? ...I don't want to draw too much attention to the fact I'm not using cats.
Thanks in advance!

#1. Mounts with header bolts to exhaust ports, usually 16 bolts per side. Depending on what type of sidepipes your talking, hooker mounts also to the frame via two "L" brackets and mounting hardware. These holes in the frame are already there.
#2. Not sure about heat as I have not driven my car yet. I assume it reduces undercar heat by a good amount except that your headers are still running near your feet and out, not under the length of the car.
I will be installing a spray heat insulation in the doors to reduce heat entering the car thru the door sills. I also have the hooker setup ceramic coated from jethot to cut down on heat. $1200 shipped includes headers and 4" pipes w/ coating.
#3. Running STS turbo baffles fully capped, this gives a nice sound. Do a search on here, you'll find sound clips and videos. If they are too loud you could stuff brillow pads or insert a sound reducer from summit.
Do a search for sidepipes and you should find a bunch of other muffler options that may suit your needs better.
Good luck

Can't help you w/the BB noise questions but when I put sidepipes on my 75 SB, it's not too loud until you step on it. Then it is.
And while I believe the interior heat factor was slightly reduced, it's still hot on a hot day. Goes w/the territory I suppose.
Good Luck!

I have sidepipes on my 74 454 and to answer your question about undercarriage heat....it does elimate it. I don't have anything fancy, they are just stock 69 pipes running out of Heddmans. Noise is no issue until you step on it.

The only problem installing the hooker super competion side-exhaust headers (I need an abbrevation for that one 
) on my '79 (SB) were the bodymounts. They were in such bad shape, the shop had to use shims to raise the body and get more ground clearance.
