Hey folks, hoping you can help me out with some exhaust questions for a 1973 Chevy Blazer. I just purchased a new SBC 350 and plan on putting new headers and exhaust on it (https://www.jegs.com/i/Chevrolet-Performance/809/12681429/10002/-1).
Current exhausted is pretty rusted, and if I’m putting in a new motor I feel like changing out headers too. Current exhaust is 2”. I’m not as concerned about tons of horsepower, as the motor is basic anyway, but do want a nice hearty sound to it. Not trying to wake up neighbors, but want people to look at it and say “man, that sounds like a nice ‘70s truck”. Of course want it to be responsive as well.
So my questions….

So my questions….
- What size pipe should I go up to? If I’m at 2” now, does 2.25 or 2.5” make that big of a difference? Most systems out there on Summit are 2.25”. My buddy actually as 3” racing headers, but would have to build it all out and read that it’s really too big for that small HP of a motor
- If the result is 2.5” as the way to go, looks like I’ll have to build that out. Don’t have that type of bending equipment, so would piece/clamp together. Is it worth it? Or should I go with one of these already complete systems (note they’re 2.25”)…https://www.summitracing.com/parts/hok-16523hkr/year/1973/make/chevrolet/model/blazer
- I’m thinking glass packs vs a turbo muffler. Thoughts on how well this would sound with the rest mentioned above?
