Header/Sidepipes vs headers true duals
I am finally at the exhaust portion of my restomod on my 77 4spd. The motor is a freshened up L48 that is totally stock.
I have been wanting Hooker, Dougs or OBX side headers and side pipes since I got the car but many people have told me that a stock L48 would sound better with long tube headers, 2-1/2" true dual exhaust into Flowmaster 40's. I want the car to sound loud and mean.
I have also been told by several people that side pipes are a nice novelty but I will grow sick of the noise and the burns on my legs or hands. I was also looking at those resonated exhaust systems but I really like the simplicity of the side headers into side pipes.
Are there any serious drawbacks to the side headers/side pipes option that I am not considering?

I dislike side pipes for all the reasons you've mentioned, plus A) IMO they ruin the lines of the C3 body, and B) Nothing beats the efficiency of factory dual exhaust mufflers from the early '70s for flow and noise reduction. A good set of headers (long or short), a crossover pipe and the early mufflers will do a better job than almost anything you can buy. Bear in mind that I haven't worked with these cars in almost 35 years. The original mufflers may not be available now, and I don't know if the Corvair mufflers that were claimed to be almost as good back then are available either. However, I'm sure there are suitable alternatives without resorting to glasspack-style exhaust (ugh).

If it's not a DD and you don't do long trips, then side pipes. You can live with the noise that's why you have a vette Put heat shields on so you don't burn your legs. The body lines of the C3 cry out for side pipes and make the car look a helluva lot better. More pros than cons for side pipes imo. I love my Hookers!

Love my side pipes with Dean's heat shields. Love the sound too. How loud it is, is up to you depending on the inserts used.

So...headers and side pipes it is. I want black. My options are Hooker, Dougs and Maximizer. The Hookers and Dougs are about $150 more than the Maximizers because I "think" that the Maximizer set comes with the Headers, the side pipes and the insert baffles but they don't come with the hardware to install the side pipes.
I assume I will need to get baffles for the Dougs or the Hookers or do I? I want the car loud but since its a stock L48 motor should I be concerned about lack of back pressure. I remember in the old days running headers and cherry bomb header mufflers in an old mopar and it would bog because of lack of back pressure.

Also... did you need the alternator bracket?

FWIW, black Hooker sidemounts here (BBC). Tho their factory paint doesn't seem to hold up very well at all, I've had excellent results over the years painting mine with high-temp/BBQ paint, heating them up so they "steam" a little during application (strip/clean them 1st). But, if I could afford I'd have Jet Hot coat them. IIRC, you can buy them already done with your pick of finishes directly from JH.
Also, I'm trying real hard not to post anything offensive regarding my opinion as to the drone of open pipes on a less than hi-perf engine; suffice it to say I rather strongly recommend you install some type of insert, whichever you may find has a preferable exhaust note. Lots of good choices out there.

I run sidepipes with STS baffles on a highly modified engine and could not be any happier with the result. Yes, it's loud. But it is "appropriate". It isn't painful and it isn't a "drone". It's not irritating. It's just not quiet.
I run covers, which are imperative. You must get them, period.
I pulled mine out of the box, and immediately sandblasted them and put high-heat paint on them. They still look as good as the day I installed them with 1.5 years and well over 2k miles at this point.

Sidepipes are more for looks/show, particularly with a stock engine. It felt like I lost some low end torque with mine. There are other annoyances, but I really like the way they look. Another advantage is it's easier to work underneath the car, you don't have an exhaust system to take down. I personally like the way a properly designed dual exhaust sounds over sidepipes. That is just my personal preference though. You can burn yourself on them, but that can be overcome with shields, which look awesome too. I don't like when my window is down, I get the smell of exhaust coming in when sitting at the light. I really hate that the most. It's really better coming out the back.

The Hooker's don't come with baffles but are sold separately which means you have choices. I went with the Hooker MaxFlow inserts. They are loud but I get a lot of compliments on how they sound. I can't recall if you need an alternator bracket as I use an aftermarket billet bracket. If you have A/C I think you will need a new mounting bracket.

I agree with most of what you said except this (which is a matter of personal preference) but I think the sidepipes actually compliment the lines of a C3. There are not many cars that look right with sidepipes, C3's do however. But I agree with you on the performance statements, along with some other annoyances. I know my opinions on this subject may not be aligned with the general forum opinions, but my opinions are based on my preferences and direct experiences. Honestly, I am considering going back to true duals on my 81. Although I will miss admiring the looks of my sidepipes as I walk by...

What baffle would be the best one to get for a stock L48 4spd? I know that Hooker makes 3 types. Reverse Flow, Glasspack and Maximum Flo. Which one would be the best choice for a stock motor?

For a stock motor, imho, it would depend on how loud you want it seeing an L-48 isn't big on performance by today's standards.
