Re: Suggestions on Upgrading Exhaust 350

When I got my truck (72 LWB C10 350/350 combo) about 15 years ago I was still in high school. I looked through the jegs catalog and bought a set of hedman longtube standard duty hedders, 3" "super 40" flowmasters with offset inlet/center outlet, and a set of jegs brand header turndowns. Not knowing squat about anything. When I got the parts i was excited to get them installed. I ended up doing the install myself. Learning that i needed a different alternator bracket, and that i needed to relocate my alternator to the driverside, also that "header turndowns" mean exactly that. Lol. So i had to bandsaw the collector adapters off the turndowns because they were expanded to the same size as the muffler outlets. I used bailing wire to secure the weight of the muffler and turndowns against the frame. This was while I was in college autoshop and 18 years old. Let's just say that it was loud. And the mufflers were directly under the cab. You couldn't hear yourself think. And I set off every car alarm within a block of where ever i was driving. Eventually i realized this was unrealistic for a daily driver. So i moved them back to under the bed and paid the local muffler guy to pipe them out in front of the rear tires for $200. He used 16 gauge aluminized mandrel bent piping 3" diameter. True dual exhaust. I still have it this way 15 years later.
