Hey guys I have a 1970 f100 reg cab short bed with a swapped 460 mild build, I have long tube headers with a dual 3 inch straight pipe exhaust mufflers dumping right before the rear axle. I'm looking to put dmh electric exhaust cutouts on the truck. Not sure where the best place to put the cutouts for sound quality. After the header? Dead center between header and muffler ? Or just before the muffler?

 

Is your goal infractions, CO poisoning or hearing loss?

Right after the headers makes the most sense installation wise. You should figure out a support for the pipe and cutout there, as this will add to the weight on the headers which could contribute to leaks, popped welds etc. However, they might end up hanging too low there.

CO & noise in the cab wise, you would put them back just ahead of the mufflers.

Depending on space available and being able to secure them and not reduce ground clearance, that location might be preferred.

Clearance is not an issue. I have plenty of room near the muffler to do so. Would sound tone be deeper closer to muffler?

 

Don't think it would matter.

 

You would want to install it about 18" behind the header collector. Helps with torque. Take the time to research your cutout options. Get the best flowing cutouts available. Some are just controlled exhaust leaks.
