...been considering going to pods and drilling out the back of the mufflers....
Imo, such drilling is ill-advised.
Might instead check ebay for an idea as to what the unspoiled stock exhaust system is worth, as some of these are bringing pretty good money, and perhaps enough to cover a 4>1 system, superior to a drilled stock muffler.
Good Fortune!

That is an excellent point. He might get enough for the system to cover a header exhaust AND the Dinojet kit.

Original/stock jetting on these carbs for the 1980 model with airbocx and 4->2 exhaust was secondary main 125 and primary main 62.
When I bought the bike it had secondary main 135 and primary main 62. It ran just fine
A few years ago I upped the secondary main to 140 and the primary to 70. It runs even better. The Keihin jets are available from Z1Enterprises for about $2 each. They dont list the smaller primaries on their website but if you want them contact them.
Different size pilots are no longer available but it is cheap to experiment with different primary and secondary sizes. I have never needed to even consider shimming or adjusting needles or doing terrible things to slides.
According to the Haynes manual all 750 E,H & L models had the same Keihin CV34s. The N1 model also had Keihin CV34s but with very different jetting and needle. The P1 (shaft) and R1 (gpz) models had Mikuni BS34s with different jetting and needles to each other
Had the bike come with a stock airbox I probably would have left it alone but as it is it came with the pods and 4->1 and I have never had a problem.
Long may it run.
Hope this helps.

If in dead he has an H3 than he has dual butterfly dual jet Keihin carbs. He will have a heck of a time to even get jets for those. Pretty much for those carbs he has no choice BUT to go with a Dinojet kit. He needs this kit and follow these instructions.

Not true! I got a jet kit (very similar to dynojet's) for my 750 e3 with keihin carbs from 6 Sigma Racing. Found them on ebay and the kit is specifically for YOUR setup (mine is v&h 4-1, k&n pods, sea level, etc). Check them out if you are looking to do some performance mods.

The question is How & Where you plan on riding it. Different pipes will give you different HP at different RPM ranges. A cannister pipe like the one I have on my bike is more of a mid range pipe in comparison to a Megaphone pipe which is more of a upper RPM range pipe. Also to warn you, a megaphone is quite a bit louder and "dronier" than a cannister pipe. A cannister pipe has a crisper and "poppier" sound.
