Thanks, Ed. The rear block on yours looks like a 6Ē lift? Would you be able to measure? Thank you.

Also, I see the rear lift on yours came with a stop extending out from the block to receive the axle bumper. Guess thatís missing from mine as well!

Finally getting around to lowering the truck. Front down to factory specs and rear lower by 2". Dual exhaust going in shortly. Any favorites when it comes to mufflers?

I'm sure everyone has their favorite, so you may get a variety of opinions. This may not be relevant, but years ago I had a '66 Nova with the 350 HP L79 engine. It had Flowmaster 40s on it when I got it. The droning noise and resonance at certain RPMs was so bad I had them replaced with Magnaflows. No more headaches! I can't say the Magnaflows were much quieter, but they were certainly less annoying.

You might find this comparison interesting: http://exhaustsystemsguide.com/magnaflow-vs-flowmaster/

You can read a lot of other opinions too, on this site: https://www.bangshift.com/forum/foru...-vs-flowmaster

Many of them comment on the annoying drone of the Flowmasters that I experienced at highway speeds.

Thx again, Ed. Iím going to go straight out the back with a smaller pipe (2 1/4 or 2 1/2). Also, not sure Iíll be doing any highway driving so think Iím going to try the 40ís and work my way down if I find them too loud.

Give the 40's a chance, I run the 50's on my truck not bad at all on noise and drone, I'm considering 40's for a bit more aggressive sound, running 2 1/2 inch pipes.

We put DynoMax cat-back on our '88 Mustang GT 5-speed in about 1993. Stock exhausts didn't last then like they do now. Bad drone at highway speeds.

Keep in mind your V-6 is a totally different animal when it comes to exhaust. I'd start with what you think would be a quieter muffler and run it 10,000 miles and see how loud it gets. A V-6 is kinda the worst of 4 cylinder and V-8 combined into one. Definitely not a smooth quiet in-line six. Think I'd run 2-1/2" pipe to the rear bumper. Your 305 V-6 needs the exhaust of a 396 V-8. It's a Big block minus two cylinders and wants to rev up under load.
