Exhaust advise
Looking for advise and or options on the matter. I have a 69 carb. sbc with an exhaust that has been on my car forever and has had several different motors through the years. I run a 4speed with 373 gears so I'm able to pull off a bigger size Hydraulic cam. and I love "old school" styling. However, I'm getting older and wanting to change up my exhaust which is a simple header system with offset turbo mufflers about midway out to rear bumper. WITH ALL of that being said.
I've been reading and study different styles and exhaust. I'm thinking I want a different look and thinking about tail pipes 45cut behind rear wheels not out to rear bumper. But I can't find any clear cut answers for...
Installing an H pipe or X pipe SOUND or Real Advantages for a Street Car ???
Advantages or SOUND for a Transverse Muffler compared to twin mufflers under the seat area ???
Muscle Car "old school" is how I roll but I am getting older {maybe wiser}. I don't want the car to be hateful inside or to nasty to drive on interstate out of town to shows.

exhaust note is subjective, each has their own opinion on what sounds best. "Generally" speaking chambered mufflers have a louder note than straight through ones with some form of matt fill between the center straight pipe and walls of muffler.
A H or X pipe will "mellow" the sound some and offer better exhaust flow
exhaust tips, again personal preference. Mine are the angled turn downs after rear tire vs the pee shooters out the end
the larger the pipe size the more TQ you give up down low rpms. Unless you are making 400 rwhp, go 2 1/4" for a street car SBC
and listening to online video sound clips is a crap shoot given each motor is different as is the pipe involved making the exhaust so take them FWIW
Me, I have a 327 with stock manifolds to true dual 2 1/4" pipe with H pipe through Flowmaster 40's to the pipes exiting behind rear tires. Basically old school classic muscle car sound. My 67 is no Cadillac and IMHO should not sound like one

Guys that have had or know...Whats the biggest difference between the FlowMaster 40's and the 44's ? Its hard to tell from any YouTube video. I know ever body has a different taste and motors etc. etc. Anyone that has had both maybe same car same motor etc. have better advise. Outside the car inside the car etc.

according to Flowmaster…
44
The Super 44 delivers a powerful rich tone and is the most aggressive, deepest sounding, highest performing 2-chamber street muffler we’ve ever built!
40
The muffler that started it all, the original 40 Series Muffler is an aggressive sounding street/strip muffler that delivers a powerful “Flowmaster Sound” you’ve heard so much about it.
